One Planet - Sac -1 Sleeping Bag - Thermolink Synthetic Fill

The Sac -1 is the workhorse of the Sac series: with a -1 comfort limit, it is at home in-house or in the outhouse! This easy-care sleeping bag is designed for general use.
The Sac is not as simple as its name suggests. It features the latest in sleeping bag technology: Thermolink fill; lightweight, breathable Vapour Vent fabric; a comfortable, efficient, tapered rectangular shape and all the technical features you expect from a One Planet bag.​


  • Tapered rectangular shape gives extra room and versatility.
  • Light, compact and durable Thermolink fill.
  • Uses strong, highly breathable 20-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.
  • Available in regular and large sizes.

Thermolink fill

All One Planet synthetic bags use Thermolink, One Planet's 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.
