This is the adjustable u-shaped pillow with a cooling fabric on one side and a warm, plush material on the other that helps travelers maintain comfort in fluctuating temperatures, available exclusively from Hammacher Schlemmer. On the pillow’s cooling side, a unique microweave fabric remains cool and dissipates body heat that ordinary pillows trap to keep your head and neck from overheating. The pillow’s opposite side is covered in soft polyester fleece that wraps you in cozy warmth, ideal for coping with a chilly airplane cabin. Unlike bulky, rigid neck pillows, this one can be folded into different configurations, and is filled with 4" of hypoallergenic memory foam that molds to the contours of your head and neck. Snaps in front keep the pillow securely in place and support the chin. The cover removes for machine washing. Imported. 28" L x 4" W x 4" D. (13 oz.)
