Rock + Run Yangra 400

Size: Regular
Zip Side: Left
Colour: Blue

The Rock + Run Yangra 400 is an ultralight 3-season, goose-down sleeping bag for alpine adventures and camping.

Weighing less than 1kg, our Yangra 400 sleeping bag punches above its weight -designed to deliver exceptional warmth to weight at a reasonable price point. Featuring a box-wall construction stuffed with 800+US fill power for outstanding warmth, a soft-to-the-touch 20D Nylon inner, and a DWR, wind-resistant Ripstop 30D Nylon outer casing for added protection from the cold.

Polish down is considered to be the best in the world and our sleeping bag is generously filled with 400g of ethically sourced Polish goose down from an RDS-certified factory, reinforced with a lofty, adjustable neck baffle and an oversized draft tube running along the main zipper to keep out any unwanted drafts. It comes with a lightweight compression sack and packs down super small for minimal bulk.

Ideal for carrying with you on multi-day summer alpine trips, or backpacking and bike-packing adventures in the UK in the spring-autumn months.
