Joel Lozanowrote a review of Pearl Izumi Elite Thermal Arm Warmers on January 22, 2015
Familiarity: I've put it through the wringer
These are the most comfortable arm warmers I've ever used. They have stitches in exactly the right places, and the thermal lining is far more comfortable than my leg warmers (LG) or knee warmers (Sugoi). I plan on buying only Pearl Izumi warmers from this point forward. I burn slightly hot, but used these on 42 mile one way commutes to work in mid to high 30s. I used a long sleeve non-thermal jersey and a merino wool t-shirt. I would recommend these to anyone, especially for the price.
