All One Planet synthetic bags use Thermolink, our new fabulous fill. This gives a massive 15 per cent increase in warmth when tested to the European standard, meaning we can make our bags 200-300 grams lighter. Thermolink is a bonded fibre, with the fibre blanket linked throughout its thickness. This makes it strong and eliminates the need for sewn-through stitching, as well as the accompanying heat loss.
• Tapered rectangular shape gives extra room and versatility
• Light, compact and durable Thermolink fill
• Uses strong, highly breathable 30-denier Vapour Vent for inner and outer fabric
• Three-dimensional hood and foot increase comfort and warmth
• The 3D neck muff and twin draft tubes on the zip keep warm air in
• Bi-directional zips allow you to vent your feet or zip the bag to others in the One Planet range
