REVIEW: Asnes Skin-Lock vs. Fischer Easy-Skin

Asnes Skin-Lock vs. Fischer Easy-Skin

So- two brilliantly designed and well-made integrated kicker skins that are only compatible with the respective skis- Asnes Skin-Lock and Fischer Easy-Skin.  I currently have the following setups:
  • 210cm Asnes Combat Nato: 35mm nylon Skin-Lock; 60mm mohair Skin-Lock
  • 210cm Fischer E-99 Tour; 205cm Fischer E-109 Tour: 35mm Easy Skin; 50mm Easy-Skin

Easy-Skin

There are sometimes some inherent disadvantages to being an “inventor”.  No matter how brilliant the idea- everyone else gets to test your idea and then capitalise on simplifying, improving and lower the manufacturing cost of their own version.

Fischer seems to have done this with the Easy-Skin.  It is a less complicated technology than the Skin-Lock- and, I would bet it is less expensive to manufacture.  The Easy-Skin is appropriately named- it truly is “easy”, simple technology.  The Easy-Skin has a plastic tab fastened to the tip of the skin that slides completely through the ski, and clips into a locking cleat on top of the ski deck.  It reminds me of a locking cleat on a sailboat- simple, functional and effective.  The transition between the skin and the base is seamless and angled, causing very little friction.  This must be the most friction-less removable kicker skin on the market.  

The Easy-Skin is a mohair-nylon composite and is available in fewer widths than the Skin-Lock (smart- less costly to produce…).

The Easy-Skin is not without its potential problems though…First of all this is a SYSTEM, as it is integrated into the ski and therefore effects its construction.  Unlike the Asnes line- the Easy-Skin was added after the fact- and I SERIOUSLY hope that Fischer has considered the effect of cutting a very large hole RIGHT THROUGH THE SKI- in a section that receives a lot of pressure and tension- the very tip of the kick zone…That hole through the ski actually makes me feel queasy- especially through skis with “xtralite” wood-air cores…I have no idea how durable the Easy-Skin skis are- they have not been proven yet.  I also see the skin wearing considerably at the intersection of the skin and the base- where it slides through the slot.  This section of the skin is bound to wear- specifically where the skin bends to go through the slot.

Attaching and removing the Easy-Skin is truly very easy- it takes seconds- I love it.  The Easy-Skins come with a reusable wide plastic sheet for storing the skins- and you can easily slide one skin on, while the other is still attached to the opposite side of the plastic storage sheet.

Current conclusion?  Love the performance of the Easy-Skin.  A bit anxious about the whole system- concerned about the durability of the ski and the skin…Not sure if I’m ready to risk my life on an expedition with an Easy-Skin ski.

Skin-Lock

Well, the folks at Asnes are clearly full of brilliant, inventive, innovative ideas- while remaining steeped in tradition.  Their Nordic ski technology is beautiful mix of tradition and innovation.

The Skin-Lock system is a well thought-out and well-made technology.  The skins are out-sourced and made by a skin specialist in Switzerland.  The skin is attached to a metal clip/cleat that clips into the base of the ski.  The ski has two tiny little slits cut into it to attach the Skin-Lock.  And- unlike the Easy-Skin system- not only are the slots tiny, they are longitudinally oriented (i.e. parallel with the length of the ski).  The whole design of the Skin-Lock system seems much more to be engineered into the fundamental construction of the ski.  My projection is that the Skin-Lock system will prove to be more durable than the Easy-Skin.

The Skin-Locks are available in an almost multitude of widths- each available in both mohair and nylon.  Perfect for the ridiculously performance-obsessed (YES- I have a disorder).  But the cost of manufacturing and inventory must be nuts.

The Skin-Lock is very easy to attach- even quicker than the Easy-Skin.  It is not as easy to remove and store however.  They need to be folded back on themselves to protect the adhesive base- and then pulled apart to mount them.  Not a big deal- same as any other conventional skin- but, not as “easy” and quick as the Easy-Skin.

My mind keeps telling me that the metal attachment cleat should cause friction and reduce glide, but- in actual practice I fail to notice it in any “measurable” way.  This is likely partly due to the effective, wax pocket of my 210cm Combat Natos.  That metal cleat might be more noticeable with a softer-flexing and/or single-cambered ski.

The Combat Nato has a milled area where the Skin-Lock cleat is attached to the base- in order to reduce friction.  Not sure if the other Asnes skis have this…

Current conclusion?  Equally thrilled with the performance of the Skin-Lock system.  The engineering of the entire ski, skin, and skin attachment at least appear to be potentially more durable than the Easy-Skin.  And- the Skin-Lock system has already proven itself to be expedition worthy.

REVIEW: Åsnes Combat NATO- the Fjell Ski

2015 Åsnes Combat NATO
A true XCD ski from the point of view of balance.  This ski truly does offer both cross-country and moderate down-hill performance.  It also climbs reasonably well for a double-cambered ski.
Fast, smooth, light and responsive.
Truly awesome flex pattern: enough stiffness and camber for efficient xcountry travel; wonderful round flex for downhill turns; low camber facilitates efficient climbing.
Beautiful broad, raised, elongated tip carves its way through snow- a trail-breaking machine.
The integrated Skin-Lock kicker skins both increase traction and extend skiing onto most any snow condition.
The very best distance-oriented, backcountry Nordic touring ski I have ever tried- PERIOD.
Is it the best at any one thing- well of course not.  BUT- it is the most versatile BC Nordic touring ski I have ever tested.  It is the best because it is good enough at everything that it just makes me smile- ALL THE TIME!!
Åsnes knows what they are doing man.

Summary

  • Excellent backcountry Nordic touring ski.  This ski defines the concept of the “Fjellski”.  A finely tuned flex pattern to offer true XC performance and moderate downhill performance.
  • Wide enough to offer reasonable flotation in deep snow- especially if you get 'em long enough.
  • Wide enough to offer significant sidecut- for those with wide-open alpine bowls (or fields/ open forest) to arc through.
  • Stiff enough to perform reasonably well on dense/hard snow.
  • Finely tuned for soft snow.
  • Truly magnificent trail-breaking kick-ass tip.  This ski may not float as much as a super fat Nordic ski- but man does it plow its way through deep snow.  THE choice if you are breaking track through deep snow with an army (or a family) following behind!  Almost leaves a groomed track behind it.
  • The integrated kicker skin- “Skin-Lock”- is wicked.  Extra traction man.  Difficult snow?  Who cares.
  • High-quality, waxable sintered base.
  • A true Nordic touring ski for the backcountry- and with a flex pattern to handle some serious terrain.
  • The modest dimensions make this ski manageable with light-duty BC boots/bindings on all but the most extreme terrain.


The model I have was bought on clearance this past spring- it is a 2015-2016 model.  As far as I know the 2016-2017 model has not been updated.
The Combat Nato is a highly versatile, high-performance backcountry Nordic touring ski.  Cambered and stiff enough to offer true XC kick and glide performance; soft enough and flexible enough to climb and turn.
The Fjellski.

Specs

I am 5’10” and weigh 185lbs.  I am skiing on the 210cm.
Here are the specs:
  • Lengths to 210cm.
  • Sidecut profile: 84-62-72mm.
  • Camber profile: low relatively soft initial camber; low profile, stiff second camber.
  • Flex pattern: the best way to describe this is balanced and stable .  Stiff enough to offer a low-profile wax pocket, and some moderate Nordic kick; yet still offering a smooth, round reverse-flex- obviously the mid-section is stiffer than the tip/tail.  
  • Broad, elongated, raised tip- moderately flexible below the raised tip.  Flat- no rocker- at all.
  • Flat tail.
  • Full length, wrap-around, metal edge.
  • High-quality, sintered base.
  • Integrated “Skin-Lock” kicker skin.


This is a double-cambered ski- despite how low and soft the initial camber is.  The second camber is low-profile and stiff.  This flex pattern underfoot meets the criteria of what some define as “camber-and-a-half”.  The flex pattern, from tip to tail, is finely tuned for skiing on soft, fresh snow.  This ski feels remarkably stable throughout its entire length.


Background

What is the Combat Nato ski?
This ski was developed for the Norwegian military- and I assume it is being produced for other NATO member countries- hence the “Nato” moniker  (SPECIAL ALERT: keep your eyes open for Army surplus sales of this ski- this is a MAJOR step up in performance over the old “Nato Planks”).  The civilian version of this ski is the Ingstad.  There are a number of upgrades to this ski that are not on the Ingstad:
  1. A titanium-enforced binding plate.
  2. Riveted hole in the tip for sledge (i.e. “helpersledge”) construction.
  3. Hole for fixation of a customized “Skin-Lock” kicker skin in the tail.
  4. Milled area at the attachment point of the Skin-Lock to produce less glide friction.


This ski is designed to be a highly versatile BC Nordic ski- for covering distance in deep snow and hilly to mountainous terrain.


This ski is classified as a “Fjellski”- meaning a Nordic touring ski designed for hilly/mountainous terrain- in other words, a ski designed to offer xcountry performance on fresh snow, with moderate climbing and turning performance.  Although, fundamentally this meets the definition of xcountry-downhill (XCD), this ski has much more XC DNA in it than modern hybrid XCD skis.  From a modern North American perspective, this ski would be classified as a backcountry xcountry (BC-XC) ski.


A ski like this precisely fits the balance between cross-country and down-hill skiing.  And perhaps most importantly in this day and age- this ski does not sacrifice XC performance in order for them to be “easy-turning”.


I have recently rigorously tested two other current skis that are similar to the Combat Nato in terms of performance: the Madshus Eon, and the Fischer E-109.  The Eon is very balanced like the Combat Nato- though it has a much softer flex pattern.  The E-109 is more finely tuned towards XC skiing.


Performance

Cross-Country Skiing

I can easily control the camber of this 210cm ski- this is no high-performance XC ski- at least not from a groomed track perspective.  But there is significant tension and resistance within that low-profile camber.  Even on dense/hard snow, this ski offers pretty decent XC kick and glide performance.  On soft, fresh snow these skis become “high-performance”.  The flex pattern of the entire ski, but specifically underfoot, is perfectly designed to offer excellent kick and glide performance on fresh snow.  But, it is not just that low-profile second camber- I feel supported by the entire length of this ski when I am XC skiing on fresh snow.  That resistance and stability allows this ski to get away with a low-profile camber.  This ski has a flat tail that helps this ski track like a XC ski should.

Flotation

Well- this is not a “powder” ski- heck it is only 62mm at the waist.  But- that being said- at 210cm, the flex pattern is soft enough, yet supportive enough, that I get reasonable flotation in truly deep snow.  And once the snow settles and stabilizes, this ski truly cruises through deep, soft fresh snow.  This ski has a lot of sidecut- with only 62mm at the waist.  I understand the physics of all of that sidecut facilitating “easy-turning”.  But- I believe it comes with a significant cost- loss of effective flotation.  I believe this ski would be better with a wider waist- say 68-70mm.

Trail Breaking

This ski has no rocker in the tip.  What it does have is a kick-ass broad, raised, elongated tip that absolutely excels at breaking trail.  It is the best trail-breaking Nordic touring ski that I have ever tested (with the old Åsnes Combat USGI a close second).  And- I am not entirely convinced that a rockered tip would be a great help to a ski with these modest dimensions- at least when XC skiing .  The tip of this ski is flexible but very stable- this allows it to carve its way through the snow, with that fat, raised tip plowing the snow to the side.  Compared to a similar ski with Nordic Rocker (e.g. Fischer E-109)- the rockered tip floats higher in the snow- but the ski is not wide enough to follow suit- plus the wimpy low-profile tip of a ski like the E-109 doesn’t plow its way through anything.  Recently, we had a big dump of very cold snow- followed by sustained high winds.  The wind consolidated and condensed the upper foot of snow- but not enough for me to ski on top of it- the skis were still breaking through and making a track.  That condensed snow was difficult to break trail through but the stable, kick-ass tip of the Combat Nato carved a perfect clean track through that snow.  The rockered tip of the E-109 floated on top of that condensed snow- leaving me trying to break trail with the kick zone of the ski- YUCK.  Although I truly appreciate rockered tips when making downhill turns- I am becoming convinced that perhaps it is a bad idea for a relatively narrow ski designed to offer long-distance XC performance.  I don’t think that the Combat Nato would break trail as efficiently if its tip was rockered.

Traction

Kick wax, klister, integrated kicker skin- lots of options here.  Kick wax?  Well what can I say- kick wax is like magic- it grips and it glides.  As I ski mostly through the North woods- full of forest debris- I won’t be using much klister on these skis.  The integrated “Skin-Lock” kicker skins are well designed, well made and perform very well.  I have a 35mm nylon Skin-Lock and a 60mm mohair Skin-Lock that I am currently using with this ski.  I bought the 35mm in nylon because I was thinking that I might end up using it in icy, abrasive conditions.  As it turns out the 35mm skin does not seem to offer enough traction on icy, refrozen snow- but, excellent traction on warm wet snow (I wish I had bought the mohair 35mm).  The 60mm Skin-Lock is serious traction for this ski with a 62mm waist- I am glad I got the mohair 60mm, as it offer better glide.  I am using the Skin-Lock regularly in the following conditions:
  1. Climbing
  2. Icy, refrozen snow
  3. Warm, wet snow
  4. Pulling a heavy load (typically a pulk-load of kids at the moment)
The Skin-Lock takes seconds to install and extends my traction greatly.  The other application I am exploring with the Skin-Lock is XC trail breaking in VERY deep, soft snow.  Over the last 15 years I have used the Karhu Guide/Madshus Annum for very deep soft snow.  However, I am finding that if I get enough traction, the 210cm Combat Nato breaks trail even better than the Guide- and it lays down a better track for that army (or family) following behind.  On the flats- the 35mm Skin-Lock is enough in very deep snow- but, if I have to climb anything significant I find I need the 60mm.  I was out on a 20km hilly tour last week in 40cm of fresh, cold, dry powder snow.  I used both the 35mm and the 60mm Skin-Locks.


Åsnes makes a customized 45mm nylon Skin-Lock for the Combat Nato- with some mechanism to attach the skin’s tail through the small hole in the ski’s tail.  I haven’t tried it- YET.


The flex pattern of this ski offers superb classic kick and glide performance on fresh, soft snow.
The camber is low enough, and easy enough to squash that these skis climb very well- at least very well for a double-cambered ski.

Down-hill Skiing

This is not a downhill ski.  However, these skis are more than manageable on moderate slopes- even with light-duty boots and bindings.  This ski has such a wonderful round smooth flex- they just feel great when equally weighted, and you have the room to let them come around in a wide-arcing turn.  They feel at their best on fresh, soft snow.  I have had them out on a couple of steep open fields where I could just ride the telemark arc- wonderful feeling.  The camber is reasonable to control on these skis and when put on edge on hardpack- this ski has good edge hold.  When put on edge on hardpack you can carve an aggressive- but wide radius- turn with this ski.  Obviously, reducing the sidecut of this ski would increase the physical turning radius.  But- I don’t see the strength of this ski is to make tight-radius downhill turns.  Fortunately, these skis are light- I can make tight-radius striding/step/jump turns with relative ease on moderate slopes.  Obviously, a rockered tip would improve turn initiation with this ski- but I feel it would lose too much of its XC trail-breaking performance as a trade-off.  This is not a downhill ski, but it sure is a lot of fun on the downhill.  Most importantly it offers enough down-hill performance that it won’t stop your desire to efficiently travel distance in hilly and mountainous terrain.


Conclusion

Åsnes Nordic ski technology is such a beautiful blend of new technology, steeped in tradition.  Every detail of this ski has been thought out, tested and finely tuned.  The Combat Nato is a dream ski for anyone wanting to do distance-oriented tours in hilly/mountainous terrain- and especially on soft, fresh snow.  The Combat Nato is a XCD ski that does not compromise cross-country performance in order to maximize climbing and down-hill easy turning.  It is light, flexible, supportive and snappy.  The full-length support of this ski, plus the broad, raised tip, make this ski a trail-breaking machine- both for yourself, and the army following in your perfectly laid track.  And- even at 210cm long- they are wonderful on the downhill.  The modest dimensions make these skis quite manageable with even light-duty boots and bindings.
There is a rumour on the street that this ski is being redesigned.  There is talk of a rockered and tapered tip...I sincerely hope not.  If so- I am very thankful that I picked up my Combat Nato before it loses it kick-ass XC trail-breaking performance.
Would I change anything?  I hate to sound like a broken record…but, I would reduce the sidecut and give this ski 68-70mm at the waist.  I would gladly take a wider turning radius in order to have more float and traction in the backcountry.  BUT- I am not going to complain!
This is the Fjellski- and I love it.
