Essential gear for uphill travel

These skins are great. They come with the trimming tool, and with a little help from a YouTube video, you can apply the tip loop and trim them to the perfect fit. They climb well on groomed or powder conditions. Couldn't be happier with my purchase.

Works Great!

  • Familiarity: I've used it once or twice and have initial impressions

So far these skins work great. I have a few short days on them so far, but both the grip and the glide have been exceptional. And I feel like they are lighter than the same ones I got a bunch of years ago. Maybe BD did some materials upgrading.
Only thing I would recommend is getting a G3 cutting tool if you plan on cutting them yourself. The offset of that tool makes the cutting job so much easier!

I have some 191 cm Wagner's being built right now, with these dimensions, 138mm-98mm-123mm. From the responses here it would appear I would need the 125mm width skins. I bought the 140's for my Voile Chargers, which are 140-114-128. I trimmed a bunch, that's true, but the skins cover the entire base of the skis out to the edge all the way along the ski. Is that not what I want? I'm confused.

Wall to wall coverage is ideal, but not totally necessary. Like you said, you just end up trimming off a ton of material. You would save a little weight and time going with the 125mm - that would cover the tail fully. You probably wouldn't notice a whole lot of climbing power improvement with the small amount of additional coverage you'd get with the 140 vs the 125, but you're definitely not wrong! Better to have wall to wall coverage than not enough coverage.

What size would you recommend on buying for 113-85-104, 179 length skis?

Responded on

I'd go with the 110 for wall to wall coverage! You could definitely get away with the 95mm if you want to save some weight, $ and time trimming but you would also be showing a little more base.

Ordering these as a gift for my daughter in MT. Her skis are 166cm, 137 / 107 / 122 mm. What size should I order?

Responded on

I'd go with the 125mm for best coverage! My skis are about the same shape and the 125mm worked out great. Super easy to trim!

Working Perfectly.

  • Familiarity: I've put it through the wringer

Not much else to say. The cutting tool that comes with them isn't great, but other than that, I love them!

What size would you recommend for my H2O Gear Ski Karen'cito Length 181 cm 165-133-149?Thanks

Responded on

These come in a standard length (188cm) that you will just trim to fit. I'd go with the 140mm waist to get the best coverage! Again, you'll trim to fit a bit on the sidecut as well.

I've got a pair of Atomic Tacora that are 120.80.106. Should I order the 80 mm or go wider and trim? Will the skin cover the ski length?

Best Answer Responded on

Always buy the width closest (or just slightly narrower) than the width of the TAIL of the ski. This will provide full coverage.

The short bit of ski that is wider than the tail (near the tip) will be trimmed back anyway to taper to the Tip Loop, so if you buy skins that wide, you'll be cutting it off anyway.

In your case a 100mm wide skin would be perfect, but it's not available in this style. 95mm will work really well, but if $8 is trivial then go for the 110mm knowing that most of the difference will wind up on the cutting room floor, but a few cm of ski will be better covered.

Comes with everything but the adventure!

  • Familiarity: I've used it several times

Well I wish I had seen Laura's picture before I purchased the skins.... I ended up buying skin savers and a trim tool as well... but alas.

These skins are THE standard. The tip loop is great and adjusts to fit on many different ski sizes/shapes. The STS tail attachment is bomber, easy to use, and also adjustable. The skins have a "rip strip"; a non-adhesive stripe runs the length of the ski to make removing the skins painless.... I wish band-aids had rip strips.

As for the skins themselves, they have tons of grip, great glide, and are rock solid.

Trimming the skins and installing the hardware is super simple; there are plenty of tutorials out there as well as the included BD instruction guide.

Once you're done with the quick setup... it's time to climb!

Yup! I would go with the 110mm width! They come in a standard length that you will trim to fit your ski.

Go-To Skins for PNW Touring

  • Gender: Male
  • Familiarity: I've put it through the wringer

I use the BD STS skins on a pair of 190cm Salomon Czars (111mm waist) with Marker Dukes. They have worked great in a variety of conditions around the North Cascades. Super easy to size and cut when the skins first arrived. Only problem I've encountered is the tail clip falling off so it's good idea to carry a few extras. I'll likely buy these or the backcountry brand skins in the future.

(Left is After, Right is Before)
Over 1/2 million vertical feet on this pair, 2nd glue refresh, pretty easy maintenance. I love Ascension skins, the best Season Pass money can buy.

Ironing with paper grocery bags pulls all the gunk right off. Touch up areas of low glue with Gold Label.

WOAH Peter! Soo cool, thanks for sharing!
That's pretty darn impressive.

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

Responded on

BD Glob Stopper will fix that for you....or you can use regular all temp ski wax too.

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!

Responded on

Another option for you would be getting the Split-STS skins from Black Diamond also! I have them on my 2010 K2 Pontoons and they are GREAT! They are designed for wide skis (120mm+ underfoot) so they will be lighter and provide you with enough grip. I have two recommendations for you in case you decide to get them. First, leave them stretching for a couple of days so that it is easier for you to cut them... don't cut them straight-out-of-the-box. And second, get the G3 trimming tool because the BD one included with the skins is useless!

Responded on

Always buy the width that is closest to the tail dimension of your skis. Once trimmed that will be the best fit.
If you buy based on the tip, you're going to be trimming off a ton of expensive material.


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,

Best Answer Responded on

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.

Trying to decide best skins for my Armada JJs (185s). New to AT so not sure on what's best for my setup (BD or G3) and what model? Thanks

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.
