Ultra 120 is the highest performance synthetic sleeping bag available using PrimaLoft® Gold to give a 1°C sleep limit and a tiny pack size.
Inspired by ultra racing, it's ideal for fast and light adventures when weight, reliability and small pack size are crucial.
Highly compressible and weighing just 580g, Ultra 120 fits easily into bikepacking bags and mountain marathon packs. We've used PrimaLoft® Gold, the highest quality of synthetic insulation available, for its excellent warmth-to-weight ratio. PrimaLoft® is water repellent too, staying reliably warm on longer trips when you can't guarantee to keep your sleeping bag dry.
Wrap yourself in gold.

Washing: 30°C gentle cycle
Drying: line dry or tumble dry on low heat until down is fully dry
Use pure soap or a technical product wash to keep your bag's hydrophobic treatment in top condition. When tumble drying use down drying balls or old tennis balls to keep the down clump-free. For more tips on how to wash your sleeping bag.
Storage: store your sleeping bag uncompressed in a cool, dry place. This will extend its life and allow it to regain its loft quicker after unpacking.
