Castelli Pro Seamless 2 Arm Warmers

Wide temperature range combined with high-stretch seamless comfort makes this our most versatile warmer.Features: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.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.
