R-Value: 5.5
Your sleep mat’s R-value is an indication of how well it will resist heat loss. A higher R-value means it will insulate you more effectively from the ground underneath, and will be better suited to cold environments.

Great product, very warm and comfortable. A bit on the bulky and heavy side but this is more than balanced out by the extra warmth and comfort.
Haven't tried it in the wild just yet but seems comfy and great value for money based on R value. Delivery was super quick. Look forward to seeing if the vertical panels help with my side sleeping.
Well worth the few 100 grams extra for the best sleeps I have had in the outdoors
Had a smaller one before this which was only 2.5inc thick and decided to try this out. It's sure comfortable and surprisingly quite compare to last one. Will deff buy this one again if it ever came too it
The Best. The most comfortable. Easy to inflate. Helps keep you warm in cold conditions.
