One Planet Sonder -5C (705 grams)

The Sonder is a streamlined, practical bag with versatile features, a spacious cut and a lighter build, designed for comfort and warmth year-round. Its available in three temperature ratings (-3, -5, -8C ISO 23537-1 limit-of-comfort rating), and small, regular and large sizes. 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!). The shell is made from durable, water-repellent and highly breathable 10 D Vapour Vent V2 fabric, with a full-length YKK #5 zip and anti-snag locking slider. A separate foot zip allows it to be opened fully to manage warmth.
