Big Agnes Greystone 0° Sleeping Bag – Rooibos, Long, Left Zip | 600 DownTek

Overview

The Big Agnes Greystone sleeping bag is built for cool-to-cold nights without weighing you down. In the Rooibos color, this 0° traditional down mummy bag blends performance with practical comfort for backpacking, car camping, or mixed-weather trips. It emphasizes warmth where you need it most, while staying light enough to carry on longer missions.

Lightweight warmth you can rely on

Designed for efficiency, the Greystone Long fits up to 6'6" and weighs about 3 lb 9 oz, packing down to a compact 9" x 13". The contoured hood and a low-profile cordlock let you fine‑tune warmth with one hand. An insulated tube around the hood opening helps seal out drafts when cinched, and the built-in oversized anti-draft collar plus a no-draft zipper add protective layers without limiting movement. For campers who travel with a tent mate, the design also supports pairing with a compatible bag for shared warmth in chilly conditions.

Materials and sustainability

Every stitch contributes to a softer touch against the skin. The shell and liner are made from soft, cozy GRS-certified recycled polyester, finished with a PFC-free water-repellent coating. Inside, the 600-fill DownTek insulation delivers loft and warmth while maintaining a low moisture sensitivity. The bluesign-certified, PFC-free water-repellent chemistry helps keep insulating value intact in damp settings, and the Down is 100% Certified RDS, reflecting responsible-down sourcing.
