Now 50% Warmer. The all-new NeoAir Trekker air mattress now features our reflective ThermaCapture Radiant Heat Technology, doubling the warmth of the mattress and pushing its comfort range well into spring and fall backpacking trips. You"ll also appreciate a weight-savings of 2 oz., thanks to some lighter fabrics - not exactly what you"d expect from something that just got 50% warmer. Stuff sack and repair kit included.
