Knee Covers

Atlas Knee Pads are built to protect you from abrasion and minor impacts when you have to bail, all while maintaining a sleek fit that barely feels like you're wearing armor. The custom-formed, anti-shock foam padding provides protection, while also remaining lightweight and flexible, so the pads become equal parts comfortable and protective. These slip-on protectors also incorporate an extra-tall cuff to keep the pads comfortably in place.

Nano Flex is a Castelli's proprietary six-stage fabric treatment that uses nanotechnology to create an extremely water-resistant surface.

With outstanding stretch, luxuriously soft and warm Thermoflex is ideal for cold weather apparel. Fleecy inside traps a layer of warm air next to your skin. High stretch allows for an aerodynamic fit.

We can officially only rate these warmers at UPF 50+, but in our laboratory tests they actually blocked 99.8 percent of damaging UV rays. We used a polyester base that is not only more effective than nylon at blocking UV rays but is also much better at keeping you dry, which means these arm sleeves are better in both cooler and warmer conditions. We’ve kept the construction very clean to eliminate seams that can rub, and we used our double-sided silicone elastic to make sure they stay in place. They fold up extremely small, so they’re great to stick in your pockets for your next big mountain day.

The Thermoflex warmers concentrate on getting everything just right.
