Thermolink fill
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.

The synthetic range is made in China due to manufacturing constraints in the Melbourne factory.
