Surprisingly useful - 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 skins are better in both cooler and warmer conditions. Weve 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 theyre great to stick in your pockets for your next big mountain day. Key Features: Solare fabric keeps the chill off without causing overheating UPF 50+ protection Polyester based for excellent moisture management Double-side silicone elastic at top for excellent grip
The Castelli Nano Flex 3G Leg Warmers are a stalwart of your winter cycling kit rain repellent, windproof, warming and luxuriously comfortable, this latest evolution of the Nano Flex technology is Castellis best yet. The Nano Flex 3G fabric used across these leg warmers utilises a combination of newly updated durable water repellent (DWR) treatment and mechanical heat treatment to give previously unheard-of levels of rain protection. Light rain beads off the fabric, keeping you dry when those inevitable rainy spells descend. On the inside of the Nano Flex 3G fabric, a super soft finish and the optimal loft have been achieved through Castellis meticulous research and development. The fabric feels phenomenally comfortable against the skin and the loft traps just the right amount of air above the skin to keep your heat regulated over a wide range of autumn and winter conditions. This latest update to the Nano Flex fabric not only reflects Castellis ongoing commitment to offering you the very best garment quality but crucially means more time enjoying yourself on the bike. The flat-lock stitching and single-seam construction keep the profile of the warmers low and the stretch is optimised for maximal freedom of movement. A dual-sided silicone gripper at the upper end secures the warmers in place. The compact size of the warmers makes them easy to stuff into rear pockets when conditions lighten up. Key Features Newly updated Nano Flex 3G fabric for exceptional warmth, softness and protection from the rain Minimal seam construction for aesthetic versatility and freedom of movement Easily packable into a pocket Highly breathable Optimal temperature range is 8C 18C
