Fit & Design: Self-inflating camping pad uses a radical hybrid design that brings the thickness of air pads and the plushness of foam together 3D sculpting technology means that you don't have to decide between weight and comfort New manufacturing allows us to remove 60% of the foam, while still increasing thickness by 290% when inflated Unique sculpted topology distributes weight effectively, so you don't need more weight With a minimum weight of 1lb 7oz, you'll hardly notice the pad in your pack Packs down to 10in x 6.5in, making it less intrusive and bulky than other models Zero-profile, micro-adjustable valve allows for fast inflation to a full 2in Horizontal coring helps the mat retain a higher R-Value with less foam
