The UnDLite base layer is made to wear under a cycling jersey. Extremely thin and form fitting, the UnDLite allows cyclists to dial in their clothing for specific temperature ranges without adding much weight or bulk to their kit. UnDLite has an amazing amount of stretch built into the fabric ensuring a precise fit. Perfectly suited for temperatures from 50-100 degrees fahrenheit (15-38 degrees celsuis) the UnDLite™ transports moisture away from your skin and dries fast so you are comfortable on your ride. Constructed with recycled fibers that are sustainable, so UnDLite is easier on the environment too. Repreve» recycled fibers are certified first quality, so they look good, feel good and are very comfortable on-the-skin.

Good quality. Two-piece construction with a rubberized upper portion of socks to hold in place. I've done a couple of rides so far, and I'm not sure about durability, but so far, so good.
