Sea to Summit UltraLight Insulated Sleeping Pad

An Air Sprung Cell pad with Exkin Platinum insulation and a 15.5 oz carry that splits the difference between the lightest possible air pad and the warmth of a true winter pad. The R-value of 3.1 lands the UltraLight Insulated in three-season territory for most climates — sufficient for shoulder-season Cascade nights and shoulder-season Rockies at moderate elevation — and the multi-function valve doubles as a one-way inflator and dump valve. The 20D face fabric is more durable than the prior generation, the Air Sprung Cell construction mimics a traditional spring mattress for real sleep quality, and the small pack size rides at the top of an ultralight pack without compress-straps.
