Pros & Cons

User Reviews

Expert Reviews
- The glue itself is great, sticking when it needs to and letting go when you want it to.
- Some of the lightest widely-available skins on the market.
- Lighter-weight tip loop system than previous models.
- Packs small enough to fit in most jacket pockets.
Reasons NOT to buy:
User Reviews
- Be careful when cutting your skins as it’s easy to make them too short.
- The narrowing of the skin at the tip lets snow get underneath, causing the skins to come off of the ski.

- Not as grippy as other options and thinner.
- Reports of the front cord fading after only minimal use.
Expert Reviews
- Issues with durability, grip, glide and glue performance after only minimal use.
- Not much lighter than the competition to justify the multiple problems.
- Enough traction for intermediates and experts, but might be too slippery for beginners.
- The skins peel off skis easier and more frequently than others.
Summary:
The Black Diamond UltraLite Mix STS Climbing Skin is supposed to make your days on the mountain easier – unfortunately, this product does not always deliver. There are many reports of the skins peeling off the skis after only minimal use, the skins not being as sticky as other options, and many issues with durability, glide, and glue performance. Even though the skins are lightweight and transport easily, you should make sure you are comfortable with the reported downsides before purchasing.
