With INEOS Grenadiers we set out to make a better seamless arm warmer. Others on the market are made with a nylon/Lycra blend that tends to hold moisture, but we knew we could get better moisture management with a polyester yarn. Working with polyester makes it more difficult to get the right stretch, return and manufacturing consistency, though. It took a year longer than we thought, but we're all glad we stuck with it. These warmers are a pro rider favorite because they're crazy light and they're extremely warm for their weight, yet even in milder conditions you don't overheat. They're so stretchy you hardly feel them on, yet when you take them off they occupy a fraction of the space that normal warmers would take in your pocket. - Mid-weight seamless arm warmer - Surprisingly warm without causing overheating - Unique polyester/nylon/Lycra 78%/15%/7% blend - Fully seamless construction - Folds up extra small

The Perfetto design ethos is driven by function, exceptional fabrics and components, and ensuring comfort in any weather while keeping the aesthetics simple and clean. The fabric here is the key, providing enough stretch for a perfect fit and easy on/off, combined with best-in-class breathability to let moisture escape, while being fully windproof and splash resistant. The oversized YKK zipper on the back is easy to open and close. We've cut the bootie high for extra warmth and finished it with a silicone elastic to keep moisture from entering from the top. This is the shoecover for those long cool-weather rides in changing conditions. - Engineered with GORE-TEX INFINIUM™ WINDSTOPPER Stretch Light fabric - Reduced seam construction - YKK Vislon zipper - Reflective webbing puller at back - Abrasion-resistant fabric under foot for durability - Silicone gripper elastic at top
