Believe it: Sleeves for warm-weather comfort.
It may seem counterintuitive to put sleeves on for a hot summer ride, but that's what you'll find yourself doing with the Louis Garneau Arm Coolers. Garneau's IceTek fabric incorporates a xylitol surface treatment. Xylitol is the organic compound found in chewing gum that makes your mouth feel cool and refreshed. IceTek fabric causes a similar refreshing feeling against the skin, as it absorbs heat from the body and converts sweat to a refrigerant.
That cooling function aside, putting on the Arm Coolers is certainly more convenient than slapping sunscreen on every time you're trying to sneak in a training ride. The Arm Coolers have a UPF/SPF rating of 50, so they provide more than adequate protection from the sun's dangerous rays. A silicone gripper at the bicep keeps the coolers from sliding down, and a reflective logo adds an extra touch of visibility. The Louis Garneau Arm Coolers are White and come in sizes X-Small through X-Large.
