For those who count every gram but refuse to sacrifice warmth, the Peak XV Hyperlite is your new backcountry essential. Weighing in at just 445 grams, this high-performance sleeping mat delivers a remarkable R-value of 4.9, offering serious insulation for alpine missions, multi-day hikes, and minimalist adventures in colder climates.
Crafted from the same ultra-durable and lightweight 20D fabric as our MaxComfort mat, the Hyperlite blends featherlight portability with rugged dependability. Its thoughtfully engineered 183 x 53 x 8 cm dimensions strike the perfect balance between packable efficiency and elevated comfort, with 8 cm of supportive cushioning to keep you insulated from rough, cold terrain.
Whether you're bivvying in the high alpine or fastpacking through remote wilderness, the Hyperlite’s compact 23 x 11 x 11 cm packed size slips easily into your pack without adding bulk. The intuitive one-way valve system ensures quick inflation and deflation, while the included pump bag keeps setup fast and hygienic in all conditions.

Decent mat though a tad narrow if you splay out.
Kept partner comfy on Abel Tasman huts – we’re buying a second.
Did an overnighter up the Pinnacles – cushioning felt plush for the weight.
Took this for the Heaphy – saved grams and slept like a log.
Only downside is the carry sack feels flimsy, but mat itself is ace.
