The Rab Ultrasphere 1.5 Sleep Mat (340g) is an air mat that's extremely warm and insulating despite its low weight and size. Offset air chambers trap excess heat, keeping you warm without any bulky insulation. That means extra warmth without the extra weight or pack size. Great for backpacking, thru-hiking, and multi-day mountain runs in warmer conditions.
