Rated 3 out of 5 by from I want to love em' but can't quite do so... I have put around 20-25 days on my pair this season and love the light weight and great packability but am concerned about the durability. On day ONE of use the skins developed 2 small tears. In the days following they have developed a few more small tears and a puncture. In my more than 10 years of ski touring these skins have shown more wear & tear than all of my previous pairs of skins combined (and I have used many light weight, nylon/mohair offerings). The glue has worked fine. Not as sticky as the Ascension's but I often do 4-6 transitions and have yet to have a problem. If I knew they'd be so intolerant to daily use in the Wasatch I would not have bought them and simply stuck with the tried and true Gluidelite Mix STS.

Rated 2 out of 5 by from Durability Issues Used 10 times in the PNW on varied conditions from wet and sticky coastal snow to fine cold smoke. Pro: light packable great glide good climbing glue sticks well (in cold temps will freeze together, really, really badly) Cons: tore the tip connector off after ten uses, less than a quarter of the season and in pre prime time touring season (Spring) longer to dry out than nylon Verdict? Try them in year two once they have fixed the bugs and stick to the previous model of mohair mix.

Rated 2 out of 5 by from They're ok I've been using these on average four days a week for the season so I've got a pretty good grasp on the pros and cons. Pros: Light. These things make going uphill a dream (if they stick) Pack down really flat. It's awesome, I can put them in my jacket not look pregnant. They dry fast too because they're thin. Glide is smoother than Michael Jackson in his prime. Really increases your efficiency on long days. They climb great provided you set a reasonable skin track, which you should be doing anyway. Cons: Glue is terrible in all conditions except -11ish degrees. In cold conditions it's just held on by tension and in warm temps I'm carrying snow in between the skin and ski. Got a little rip in one skin on my first day. To be fair BD immediately offered to replace the set however it seemed like a waste to throw a pair away so I didn't accept. More rips as the season progressed and we've had a pretty good year so I don't think it's because I'm skinning on rocks. Bottom line: Probably not going to get more than one season out of these. Grip and glide is amazing but you really have to baby them and refresh the glue multiple times a season.

Rated 5 out of 5 by from good tool to earn your turns... Been using the UltraLite Mix STS for more then 30 days past winter and I am super happy with that skin. Had no problems at all. Used them on my Carbon Convert 180 and on my Helio 185, just changed the position of the back clip... Like the lightweight and pack volume very much. Never used the cheat sheet and it was not difficult to pull the skins apart. Only for storage in summer I put the sheet... First I thought the skin will wear out fast, but it doesn't show more use marks then any other lightweight skin I used before... even thought the tip piece will not last, but no damage on it yet... the skin never came off, even putting it on several times a day... will use that type of skin in the future... good tool for my guiding activities...

Rated 1 out of 5 by from Tip connector is too narrow I have used these for one season with my Helio 116 skis (which by the way are awesome). Unfortunately they roll up from the sides and collect snow underneath. I've tried recutting them thinner and thinner in the tip but nothing works. The tip connector is just too narrow for wide skis/skins. Just make it wider, it will only cost a couple of grams. I had to go and buy a different pair of skins instead

Rated 2 out of 5 by from Tip String WAY TOO LONG Be warned the tip clip string drops the bulky attachment way down from the tip towards the flat ski surface (Volkl VT88 and DPS 99), it acts like an anchor defeating the point of the great skin material. Already cut and attached so no recourse for me. I'll have to order new adjustable tip attachment when they have them back in stock. Love the weight of the skin. Great performance going up, glide compromised by tip attachment location.

Rated 2 out of 5 by from Good skins, but bad tip conenctor is flawed Good skins overall, unless there is lots of snow. I like that they are lightweight. Used them 6-7 times now. They tend to get wet and snow can stick on the plush if warm weather but not a major issue. What i'm struggling with, however, is the tip connector. It is too narrow and too low on the skis so snow necessarily creep between the ski and skin depending on the snow and length of usage. Had to break trail yesterday and so much snow got in that I could not put the skin back on for a second hike up. I had to use two ski straps... which takes away the benefit of the skins I was looking for. I'm thinking of buying the Ascension tip connector to replace this one, but will have to cut about 4 inches of the upper part of the skins to make it fit... so not sure I have enough. I was hesitating between the STS or the Ascension... should have gone with the other ones..... :(

Rated 3 out of 5 by from Compact, good traction, no glide. I have used these skins a total of one day so I am unable to speak to durability. The tip loops are a pain to install but that is a one time thing so its not a deal breaker. The skins pack down pretty compact. They seem to have traction comparable to the previous generation of Glidelite's but these ultralights have significantly less glide than the old solid orange nylon BD ascension skins.
