Ultra 80 is the highest performance synthetic sleeping bag available using PrimaLoft® Gold to give a 5°C sleep limit and a tiny pack size. Inspired by ultra racing, it's ideal for fast and light adventures when weight, reliability and a small pack are crucial. Highly compressible and weighing just 490g, Ultra 80 fits easily into bikepacking bags and mountain marathon packs. We've used PrimaLoft® Gold, the highest quality 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.

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.
