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.

Reducing our carbon footprint
We are carbon neutral under PAS2060 and offset our Scope 1, Scope 2 and Scope 3 operations and transport emissions. We recognise that offsetting is not part of the solution but a point to pass through on a journey to Net Zero. Carbon Neutral is just a step in that journey.
We have joined the Science Based Targets Initiative which sets independent targets for us to achieve to do our bit to limit global warming to 1.5°C. Our targets are to halve our Scope 1 and Scope 2 emissions by 2025 based on 2018 base year and reduce our total carbon intesnity by 15% every year to achieve genuine net zero by 2050.
