What Our Gearhead(R) Experts Are Saying:"I threw the Espresso 2 Arm Warmer on for a chilly sunrise ride and forgot I was wearing it within a mile. The raw-cut wrist never dug in, and the silicone gripper up top kept everything in place through a couple hours of climbing and descending."Early rides have a way of starting cold and ending warm, and the Espresso 2 Arm Warmer is built for exactly that window. Castelli made this arm warmer for riders who'd rather adjust a layer than turn back for extra clothes, because it slides on in seconds and holds up through a full temperature swing without ever feeling bulky. The single-piece construction keeps seams out of the way, so there's nothing to rub or bind through hours in the saddle. A silicone gripper at the top holds the warmer in place through climbs and sprints alike, and the raw-cut wrist finish means no chafing once the sun comes out and it's time to roll the sleeves down.
