The Rock + Run Eiger 500 is a versatile 3 season, mummy-shaped duck down sleeping bag for temperate climates.

The Eiger is a well-rounded sleeping bag designed with versatility, comfort and value in mind for all of your camping excursions during spring, summer, and autumn. Featuring a box-wall construction stuffed with 620+US fill power for plenty of warmth, a soft-to-the-touch 20D Nylon inner, and a DWR, wind-resistant Ripstop 30D Nylon outer casing for added protection and warmth.

Polish down is considered to be the best in the world and our sleeping bag is generously filled with 500g of ethically sourced Polish duck down from an RDS certified factory. Backed 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, allowing you to neatly pack it down and take it with you, whether you're camping in the fells, sleeping out in the van or heading further afield.
