Ultra 80

Ultra 80 is the highest performance synthetic sleeping bag available using PrimaLoft Gold to give a 5C 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.
