Adam B.wrote a review of Pearl Izumi Pro Barrier Arm Warmers on December 10, 2012
Bought these Pro Barrier Arm Warmers as upgrade to Thermal Lite arm warmers. Used them in 50-60F conditions. They were amazing on a long cold descent. Felt zero wind chill. Fold up nice and small so easy to stash and prevents needs to bring along a full sleeve jacket. The fuller length gets right under a jersey sleeve so no gaps exposed to wind. I will use them with a short sleeve jersey and sleeveless wind vest. Great for temps down to 45F, beyond that I would need more solid body covering. Recommend for cool-cold days but not for freezing days.
