Super grip. I was shocked at the pitch they can hold onto. I have however had them clump up a lot in wet snow.

I have Atomic Bent Chetler 192 ( 144.5-123-136.5). Will the 125mm work or should I go for the 140mm?

Responded on

Depends on if you are going for a straight or shaped cut - shaped will give you more coverage (increased traction on the climb). 125mm would work and be slightly lighter weight, but I'd probably go with the 140mm for better coverage/grip overall!


I have just bought a Black Diamond...


I have just bought a Black Diamond Current 2014 Skis ( [175 cm] 118-86-106 ) and am looking for skins for those.
Could any of you let me know which size I should go for?
Also what's the differences between Black Diamond Ascension Nylon STS Skins vs. Black Diamond Ascension Nylon Custom STS Skins?
Also does the package includes a pair + cutter?

Thx in advance,

Hey Balazs,

You have two options you can get a skin that provides full coverage that you trim to fit the shape of your ski-125mm size skin.

Or you can have a straight skin that matches the waist of your ski leaving some exposed base on tip and tail-95mm size skin.

the advantage of the straight skin is it is lighter and easier to fold up, but has less grip.

the difference between the custom and this pair is that the custom is precut to fit the length of your ski, where with this skin you have to cut the skin to fit the length and then attach the tail clip.

How long are these skins??

Hey hgrp698955,

Thanks for your question.

Length of the skin itself is 188cm; including the STS tail, total length adjusts from 195cm - 200cm. You cut the skin to the correct length of your ski.

That's a difficult question to answer because there are a lot of other factors (including conditions and terrain)that need to be considered. Maybe give one of our experts a call and pick their brain.

Gets the Job Done

  • Familiarity: I've put it through the wringer

Great preforming skins! They provide great grip everywhere around the Lake Tahoe Basin. They haven't had a problem with even the wet and heavy spring snow here in Tahoe. I have not had a problem with these skins yet. They are super easy to trim and maintain. Another solid Black Diamond product.

I received a pair of these in 125mm, but my skis (Surface Live Free) are 110mm in the waist. Do you foresee any problems with cutting these down to 110mm? Thanks.

Best Answer Responded on

There is nothing wrong with cutting skins down to fit the ski, in fact that is exactly what you're supposed to do. Skins should be bought to fit the widest point on the skis and then cut to just allow the edge of the ski to be uncovered, in order to get maximum surface area and max friction on the snow.

Great Skins!

I gave these as a gift, but the user was the following to say:

These skins are great! Easy to put on, excellent grip, and seem like they will hold up well.

Climbing to awesomeness!

  • Familiarity: I've used it several times

So I have last years model of this skin and they are awesome! Took them out for the first time this year and they performed perfectly. I felt really confident up the skin track and slipped on the steeper stuff but that was because I wasn't engaging the skin properly through my ski (aka: oh yeah there is camber in my ski and I need to step down in order to make full contact of the skin to snow. HAHA).
I really enjoy how easy it is to apply the skin and taking them off is a breeze when you have your toe and tail clips set. The glue is amazingly sticky especially when dried after use. The cutting of the skins and installation of the toe loop and tail clip wasn't hard at all but I would definitely watch the youtube video Black Diamond has online first just to get an visual. The thicker material is heavier than most skins I have seen but at the same time I think it helps the skins last a lot longer and for a lot more laps.
I didn't have a problem gliding and felt that these skins did their job and I?m very happy with them. As you can see from my picture the skin doesn?t cover the whole bottom of my tip and it doesn?t for my tail either but I felt that it didn?t affect the traction at all. Also I cut my skins to be edge out (which means my edges are not covered by the skin) and I find that it helped keep me on unevenly cut tracks or even setting a track. Over all I really like these skins and I would recommend them for any first touring set up.

Hi, I need skins for my 188cm Soul 7s...

Hi, I need skins for my 188cm Soul 7s (137-108-127) and my wife's 170cm Kikus (139-107-123). I am particularly keen to get the right size for the Kikus?

I am surprised at the sizing recommended below but only because the recommended size for S7s on the BC climbing skins was to go for the 140mm. Please can you explain the difference?

also- do I need to buy the tail connector and any other kit to go with this?


Best Answer Responded on

First, you do not need to buy a tail connection separately.

Second, the 125mm width recommended below is perfectly valid, as is the recommendation you saw for a 140mm width skin elsewhere. Sizing climbing skins is in many ways a subjective pursuit. There are several sizes that absolutely will not work for a given ski. But there will probably be two if not three widths that will work depending on how much cover you prefer on the bottom of your skis.

On the Kikus for example, you could get the 140mm width and you would have tip to tail coverage. Seamless!

However, some people prefer a narrower width either because they don't want to trim the skin down as much in the waist, or because they actually like a little base/edge uncovered in the tip and tail.

If you have a ski with almost zero rocker, you are probably better served to get full coverage, but if you have rocker in tip and/or tail, that full coverage immediately becomes less important.

What is the recommended width for Soul 7s -- 136 / 106 / 126 mm -- 140 mm skins cut to fit or 125 mm skins?

Best Answer Responded on

125 mm will work perfect for the Soul 7's. Your main concern with sizing skins is getting the waists and tails of the skis covered, which the 125's will do.

Great for going up hill

  • Familiarity: I've used it several times

If you're somewhere with steep skin tracks and less flat-land travel, then the BD Ascension is the way to go. I'd previously skied a lot in the Cascades and BC, and preferred skins with more glide for approaches and glacier travel. But living now in the Wasatch I'm loving the Ascensions.

The tip & tail connectors seem pretty bomber. Certainly as good as G3 or other systems I've used.

tried and true!

  • Familiarity: I've put it through the wringer

Second pair of these. The first lasted three seasons, never had to re-glue. Take a pair of skin wax if you expect heavy wet snow. Just cut the new pair and looking forward to my next climb (BD has a nice how-to video on how to cut your own skins, btw). The kit came with everything needed to cut and assemble. If you are not confident in doing this... go to your local ski shop. Don't waste a good pair of +$100 skins on a bad cut job.

Looking for the right size STS for my Atomic Blogs.

Any advice is recommended. I'm debating full coverage with the 140's vs 125's

Responded on

I would agree that you can go either way here. The Atomic blog has 20% nose and tail powder rocker, so those uncovered areas with the 125mm will be minimal and won't be contacting much at the tips. The 125 would be my choice. But, if you like your peace of mind and don't want to risk any possible slippage, the 140mm will fit great with some substantial trimming.
