What size would you recommend for Voile Chargers 171cm, 134-110-123

Skinning excellence

  • Familiarity: I've put it through the wringer

Love 'em, trust 'em, and have been using this brand of skin for a long time. Combine these with a tech binding and you can skin much steeper terrain than we did with skinny skis and frame bindings. They climb great and are durable. Black Diamond purchased Ascension and has improved their product. The STS is my favorite of the bunch. They do have a bit of a learning curve and the STS clip parts can wear out or break before the skin does. I recommend carrying duct tape and skin wax. Should you have an issue just be prepared. They are simply great in all snow conditions.

Skinning excellence

How long are the 65mm wide Black Diamond Ascension Nylon STS Skins?

Responded on

Hey David,

These skins are 200cm long and the STS tail allows for 10cm of length adjustment.

Great skins (limited experience)

Just got back from my 1st ever backcountry skiing day. The snow was spring snow, pretty heavy and wet but the skins gripped well on the uphill, did not attract snow (the guy I was skinning up with had to stop several times to clear his 15-year old skins of ice). Overall pretty happy with my purchase and I can't thank Bill Porreca enough for the fantastic customer service and helping me get the right cutting tool for the job (G3!).

Great skins; I own 2 pairs...have trimmed both several times now to fit different skis. I haven't had any tail clip issues as some others have stated...I'd guess they just need to be tightened down a bit more if they're popping out/off. The toe loops don't do well with wide/fat skis, I've had mucho issues with them coming off the toe frequently and repeatedly...super annoying. Glue seems to be super grippy...they can be a bear to peel apart if they stick together. Besides the issue with the toe loop coming off, another issue I consistently have is snow sticking to the bottom in warmer conditions. These are also fairly bulky and space consuming if that's a concern. more thing...the new storage bags kind of suck. The older Black Diamond storage bags with the drawstring tops were a tad easier to handle than these IMO. Good skins all in all though. Would definitely (and probably will) purchase again.

What size would fit 191 cyclic 115's? Will the 140's be large enough?

Responded on

The 140 would be the way to go.

You can call or email me directly. 801-736-6398, or

would these work on armada tsts 183? (i believe the dimensions are 119-132-102-123). Thanks

Do they sell by the unit instead of by pairs?
I completely botched trimming my first ever skin and now it's cut and misaligned.

Responded on

No they do not sell them in one single unit, only as a pair.

Never any problems

I've had many pairs of these. The STS tailclip seems to be the best that I've seen. Grip is good.
Only niggles are that the glue strength can vary a lot - never had a problem as such but my stickier ones take quite a lot of grunt to get them a part (nothing that a few pine needles cant resolve). If you have very wide / square tips then the tip loop doesn't hook so securely, but never a deal breaker for me, finally they are quite stiff / heavy so if you have big wide skis then they can take up a lot of room in your bag.
For sizing I tend to get them wide enough to go wall to wall on the tail but don't worry if you are a touch too narrow for the tip.

Great for climbing, but the tails?

  • Familiarity: I've used it several times

These are climbing skins. Glide is average, as expected with full nylon skins. My problem was with the tail clips. Constantly fell off. Surprised BD doesn't offer a better tail clip like the ones G3 or Montana uses. Returned for this reason.

Responded on

I've often had that problem with BD skins.
Maybe we need to get them tighter?

So far, so good

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

Works as advertised. Only time will tell on durability.

I didn't have an issue with the BD trimming tool. I wouldn't spend extra money on another one.

First pair of skins; could use help choosing the right size for BD Megawatts - 188cm 147-120-127

I want to put these on Hagan Cirrus 170's. Dimensions are 113 shovel, 75 waste, and 95 tail. What size do you think works best here?

more grab for your buck

  • Familiarity: I've used it several times

I use these skins with my Armada VJJ's and they have been awesome for climbing. They make the uphill a smooth travel and grab on everything, haven't been sliding at all. They are very easy to clip on to your ski and I haven't had any issues with them not sticking properly. Also quick and easy to set up and store.

The tool that Black Diamond gives you isn't the greatest for trimming. I used the G3 Trim tool which worked amazingly. Awesome skin that I would definitely recommend for anyone getting into the backcountry!

Great for the uphill.

  • Familiarity: I've put it through the wringer

These skins are great!

They are incredibly grabby and will handle any kind of snow you throw at it. They aren't the glidiest skins ever but I don't find myself going downhill with my skins on very often.

The install was incredibly easy. It took only a few minutes. I will say that part of the reason it was so easy was because of the G3 trim tool(item# GGG0128) which will trim to expose your edges. The STS clips are fantastic and I have yet to have a skin pull away from the ski.

The skins come with both a bag to store them in and skin savers(which both help make for a faster transition).

I use these on a set of 4FRNT Hojis and got the 125mm skins.

I have the Icelantic Nomad at 181, 140-105-130. I see that the 140's are not available so will the 125's suffice?

Responded on

Hi there,
Yep the 125s would provide enough coverage to work well on the Nomads!

Great Skin!

This skin was a breeze to set up! It does come with a cutting tool but I ended up using the G3 Trim Tool which also cuts the extra 4mm to reveal your edge!

Great Skin!

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.

Best Answer Responded on

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.
