Gossamer Gear is a leader in the ultralight hiking community. They specialize in ultralight backpacks, but they also sell other accessories which can save you a lot of weight. The NightLight Sleeping Pad, in the 29″ size, only costs $24 and weighs 2.4 oz.
The NightLight has an egg shell-like surface and is 3/4 inches deep with an approximate R-value of 2 (they’ve never actually tested it). It’s good for 3-season use if you’re not a cold sleeper and it is more comfortable for people who sleep on their backs than side sleepers. I normally use this pad when hiking through heavily wooded areas like the Catskills or White Mountains where I can heap together a lot of leaves under my tent to augment the pad’s insulating properties and overall comfort. If you have to sleep on a platform or hard ground, think about bringing a thicker sleeping pad instead. You can thank me later.
The NightLight is meant for hikers who have ultralight frameless hiking packs like the Gossamer Gear Mariposa or Gorilla which have an external foam pad holder between the pack’s shoulder straps. When inserted into the pad holder, the NightLight Sleeping Pad acts as an internal frame, stiffening the pack. It’s a brilliant piece of multi-use engineering really, and one of the signature differences between Gossamer Gear packs and every other ultralight backpack made today.
