Mountain Hardwear Way2Cool Arms sleeves utilize an active-cooling technology called Cool.Q ZERO, which is built right into the fabric, for the ultimate offering in hot weather comfort and sun protection.
Thanks to Mountain Hardwear’s Cool.Q ZERO fabrication, Way2Cool Arms Sun sleeves produce an immediate and ongoing cooling sensation when they come in contact with your skin. Tiny circles in the fabric are filled with a lightweight, sweat-activated cooling agent that lowers the overall temperature of the fabric itself, thus accelerating the wicking process and helping you stay cooler. These silky, soft fabric sleeves keep the sun’s rays at bay and are simple to put on and take off. They roll up easily when not in use so you can stow them in a pack or hipbelt pocket.
The Mountain Hardwear Way2Cool Arms Sun sleeves are available in three size options.
