Ultralight, weighing just 340 g, and ultra-compact, it slips discreetly into your backpack or bikepacking panniers. It offers excellent overnight comfort thanks to its 8 cm thickness and compartments that optimize weight distribution. What's more, it has an R-value of 1.3.
It's made from 20D recycled polyester and coated with a fluorocarbon-free DWR water-repellent treatment. Its contoured shape adapts to your sarcophagus sleeping bag and saves a few grams.
