Pro Seamless 2 Arm Warmer drop hem Internal mesh dump pocketWide temperature range combined with high stretch seamless comfort makes this our most versatile warmer. 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.
