Although lightweight and aimed at summer riding these arm warmers from X Bionic still retain some compression benefits thanks to the use of fine yarns. The fine yarns also keep the rays off although we couldn't find a particular UV rating in the specs.
One piece construction eliminates the potential for chaffing and irritation from seams and expansion ribs at the elbows work brilliantly, giving you plenty of articulation and no noticeable cold spots.
The inside has a slightly Roubaix finish which feels plush and luscious as well as taking the bite out of a chill in the air. The various different channels and ribbing are designed to help regulate body temperature, they certainly felt pretty spot on during a ride on a spring day and of course if you do start to overheat you can take them off and stash them in your jersey for the ultimate in temperature regulation.
