One Planet Sonder

The Sonder sleeping bag is a streamlined, practical bag with versatile features, a spacious cut and a lighter build, designed for comfort and warmth year-round. It features Storm foot technology: the foot-box is made from waterproof, windproof, breathable fabric for warmer feet, maximum loft and better performance. The Sonder is available in three sizes – small, regular and large – and three temperatures (lower limit of comfort for males/females -5/+1°C , -8/-2°C, -10/-4°C, all independently tested in accordance with ISO 23537-1). The Sonder is filled with top-quality 800-850 loft hydrophobic down encased in a highly breathable, DWR-treated 10-denier Vapour Vent (V2) shell. (Both down and fabric use non-PFC DWR.) The tapered rectangular shape gives space to move, while the Vertical V baffle system and draft tube keep warmth where you need it, even as you wriggle around. There’s a full-length YKK #5 zip and anti-snag locking slider, while a separate foot zip allows the bag to be fully opened to manage warmth.
