The Cloud Peak 200 is designed for camping in the warmer half of the year. Excelling in damp conditions, it's ideal for overnight bivvies or soggy backpacking trips where you can’t guarantee good weather.

  • Synthetic fill keeps its insulating loft when damp
  • Durable outer fabric that can take a beating
  • Fill withstands repeated compression and washing

The Cloud Peak 200 uses 200gsm Thermolite® Ecomade fill, compressible synthetic insulation with a high warmth to weight ratio. Thermolite keeps its insulating loft when wet which makes it ideally suited to 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.
