Never used. I unrolled it and realized it was too long for me (I'm 5'8" and don't need a 6' sleeping pad). But it is very comfy. Normally $118 ($84 on Amazon) About this item HYBRID SLEEPING PAD - The new Flyer self-inflating camping pad uses a radical hybrid design that brings the thickness of air pads and the plushness of foam together. New technology allows us to use 3D sculpting to completely redefine self inflating sleeping pads. No longer do you have to decide between weight or comfort. The Flyer does it all. MAXIMUM SUPPORT - Our completely new manufacturing approach allows us to remove 60% of the foam while still increasing thickness by 290% when inflated. The unique sculpted topology distributes weight effectively so you don’t need more weight. That means more comfort with less material, allowing you to recover quicker after a hard day on the mountain. ULTRALIGHT - With a min. weight of 1 lb 7oz you’ll hardly notice the Flyer self inflating sleeping pad in your pack. Made with 20D soft-touch polyester, the Flyer packs down to a 10 x 6.5 in dia, making it less intrusive than other models. When you’re ready to setup camp, the zero-profile, micro-adjustable valve allows for fast inflation to a full 2 in. R-VALUE - The ideal camping pad shouldn’t just be lightweight and comfortable. It should also keep you warm. Horizontal coring helps the Flyer sleeping mat retain a higher R-Value with less foam so you don’t have to sacrifice weight or size for warmth.
