Mountain Equipment has given its Extreme Light sleeping bag range a big update for spring, producing bags that push the boundaries of the warmth-to-weight ratio.
The Xenith Sleeping Bag collection, which already featured an astonishingly low weight and pack size, has been redesigned using the brand's secret weapon: Plasma 10D fabric. Now they're even lighter than they were before, while still keeping you warm in temperatures as low as -8°C/18°F.
