The Sonder streamlines versatile features, a spacious cut, and a lighter build. A sensibly different combination for comfort and warmth year-round. Available in three temperature ratings (-3, -5, -8 ISO 23537.1 limit of comfort) 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. There’s a separate foot zip so it can be opened fully to manage warmth.

Features
Tapered rectangular shape offers versatility and roomy comfort
Box-wall baffling gives maximum thermal efficiency
The vertical baffle system (Vertical-V baffle system baffles) blocks the migration of down, keeping it trapped where you need it most
Differentially cut baffles promote full and complete lofting of down
The half-moon foot-box is wide and cosy, while base draft tubes keep you warm and toasty
The contoured hood encloses your head, cinching tight while leaving enough space for your nose and mouth
Full-length side zip runs from hood to ankle: a YKK #5 with locking slider and innovative, anti-snag cover
Independent zip on the foot (from ankle to ankle) can be opened fully for extra ventilation
The two zips meet above the ankle, with a 10 cm crossover to keep draughts out
Selecting a zip side is easy: when lying in a sleeping bag, a left-hand zip (LH) is on your left side
Joined at the zip: full-length zips allow models with compatible left and right zips to be zipped together
Hydrophobic down repels water, helping down stay lofty in all conditions
Your choice of down: ethically-sourced hydrophobic down in either 700-750 loft, or lighter (but just as warm) 800-850 loft
Water-resistant thread is used to make a durable, well-sealed sleeping bag
Hang loops on the foot-box allow you to easily hang, dry and store your sleeping bag
