The Rab Ultrasphere 4.5 Sleep Mat (370g) is an award-winning air mat that's extremely warm and insulating despite its low weight and size. Two layers of heat-reflective TILT combined with offset air chambers radiant heat back towards your body and 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 milder conditions.
