The Cloud Peak 140 is a summer weight 1 season sleeping bag using Thermolite insulation. Hard-wearing and excelling in damp conditions, it’s an ideal sleeping bag for summer bivvies, festival camping and warm weather bikepacking.
- Thermolite insulation is highly compressible and recovers well for repeated use
- Synthetic fill works better when damp, ideal for multi-day trips
- Durable outer fabric can take more of a beating for regular camping
Keeping your sleeping bag in top condition isn’t easy, especially in wet conditions, on multi-day trips or for whole seasons of use. The Cloud Peak 140 uses 140gsm Thermolite Ecomade insulation, a compressible fill with a high warmth to weight ratio. Like other synthetic fill, it retains its structure when damp, keeping you warm and not clumping like down can. This makes synthetic bags ideally suited to damp or condensation-heavy bivvying and camping.

We’ve combined this long-lasting insulation with a hard-wearing nylon ripstop outer, to make Cloud Peak 140 a sleeping bag that’s designed to stand up to repeated heavy use. The outer fabric is treated with a PFC-free water repellent for extra damp protection.
Designed with a slightly tapered mummy shape, which uses less energy to warm up, the Cloud Peak 140 also uses a stitch-through construction to keep its weight down. A drawstring closure hood and neck baffle, and full-length zip baffle are there to keep out unwanted summer breezes. The Cloud Peak comes with an adjustable stuff sack to pack your sleeping bag down as small as possible.
