Excelling in UK conditions, the Cloud Peak 400 is our warmest synthetic sleeping bag – ideal for damp winter camping and cold weather backpacks.
The Cloud Peak 400 uses 400gsm Thermolite® Ecomade fill made with 35% recycled post-consumer waste. It is compressible synthetic insulation with a high warmth-to-weight ratio. Thermolite® keeps its insulating loft when wet, making it ideal for camping in cold, wet climates. It also gives you the security of knowing your sleeping bag will still keep you warm at the end of a long backpacking trip, or after a whole winter of use.
Thermolite® is highly compressible and recovers better from being bundled into stuff sacks. This provides long-lasting loft, season after season, extending your bag’s lifespan. It has much better washing durability too, so you don’t need to worry about bunging your bag in the washing machine when it gets a bit funky.
We’ve designed the Cloud Peak range to stand up to the demands of repeated heavy use. As well as the robust Thermolite® fill, we’ve chosen a hardwearing nylon ripstop for the outer fabric. This is treated with a PFC-free water repellent for extra damp resistance and protection from catastrophic tea spills.
A slightly tapered mummy shape uses less energy to warm up and the full length zip baffle reduces heat loss. The hood and neck baffles can also be cinched right down to keep you snug and draught-free.
AK Sleep Limit: -8°C/17.6°F

How It Is Made
Thermolite® EcoMade is a polyester-based insulation using 35% recycled content, including from plastic bottles.
The Cloud Peak uses a PFC-free durable water repellent treatment on its outer fabric to help shed moisture. PFCs are potentially harmful chemicals that have been found to build up in the environment.
Where It Is Made
Our products are made in the best factories in the world. We know the factories personally and they have all signed up to our Code of Ethics in our supply chain. This includes the Ethical Trading Initiative base code, fair pay, safe working environments, no child labour, no modern slavery, no bribery or corruption, no materials from conflict zones and humane farming methods.
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.
