The ULTRASPHERE 1.5 LONG WIDE mattress from Rab is an essential accessory to take with you on multi-day adventures in the great outdoors where temperatures are low.
Ultralight, weighing just 476g, and ultra-compact, it slips discreetly into your rucksack or bikepacking bags. It offers excellent comfort during the night thanks to its 8 cm thickness and compartments that optimise the distribution of your weight. What's more, it has an R value of 1.3.
It's made from 20D recycled polyester and finished with a fluorocarbon-free DWR water-repellent treatment. Its streamlined shape adapts to your sleeping bag and saves a few grams.
