Two types of insulation prevent radiant and convective heat loss – the mats have a tested R-Value of 3.1, and the lack of internal air movement means minimal loss of warmth compared to other designs. Noisy when I shift around in my sleep? No. The reflective material (Exkin Platinum®) and the outer laminate material are both very quiet. Your tentmate will thank you in the morning.

This guarantees greater comfort no matter what position you may sleep in, and perfectly matches Sea to Summit’s Women’s Sleeping Bags. The uprated 30D / 40D face fabric is quiet and durable, and the lamination technology continues Sea to Summit’s class-leading reliability. IS THIS INSULATED AIR SLEEPING MAT…? Really comfortable despite being 2” thick? Yes. Thickness is not the key factor in an air sleeping mat; the number of points of suspension is. Your weight and contours rest on 174 individual air-filled springs (size Regular). Warm enough for three-season camping? Yes. Two types of insulation prevent radiant and convective heat loss – these air sleeping mats have a tested R-Value of 3.5, and the lack of internal air movement means minimal loss of warmth compared to other designs. Easy to inflate? Yes! The supplied stuff sack features an integrated Airstream Pump – just a couple of breaths will inflate the air sleeping mat. No dizziness for you, and practically no condensation moisture inside the air sleeping mat. Genius!
