Therm-a-Rest Z Lite Sol Sleeping Pad

An air mattress that goes flat at 3 a.m. on night two is a festival classic, and this foam pad simply cannot do that. There are no valves, seams or chambers to fail, so a stray tent peg or a sharp bit of ground is no threat. The Regular weighs 14 oz and has an R-value of 2.0, which keeps the cold, damp ground from stealing your heat on a summer weekend. It unfolds in seconds and doubles as a dry seat in front of the tent or a mat for muddy boots. The trade-offs are real: at 0.75 inches thick it is firm, and its folded block is bulky, so strap it to the outside of your pack for the walk in. Side sleepers may want it under a thin air pad.
