The Greystone 20° mummy-style sleeping bag delivers excellent value and performance in a lightweight package, designed with sustainability in mind. This bag is an ideal choice for backpacking, yet it's versatile enough for casual use. Greystone sleeping bags feature 600 fill DownTek insulation, recycled shell and lining fabrics, and a water-resistant coating to effectively repel moisture. This sleeping bag is your ticket to comfortable and warm nights, whether you're out on the trail or simply seeking cozy rest.
The All-Gender Greystone bags deliver technical, lightweight performance, excelling both on and off the trail with high thermal value, compressibility, and comfort wherever you go.
A water repellent coating, without intentionally added PFAS, helps keep you dry without the use of harmful chemicals, promoting environmental responsibility.
The traditional mummy shape reduces bag volume, contributing to its light weight and allowing your body to heat the bag to a comfortable temperature more quickly for increased warmth retention.
A contoured hood follows the shape of your head for a more comfortable fit, while an oversized no-draft collar and no-draft zipper effectively seal out the cold. An insulated tube along the upper hood opening further seals out drafts when cinched.
A low-profile cordlock allows you to uncinch the hood with just one hand, offering convenient temperature regulation.
Features a 65"/165cm YKK #5 anti-snag locking zipper for a smooth, quick zip. The two-way zipper and Zipper Garage are positioned on the sleeper's left side of the bag, allowing for versatile ventilation.
Left-zip (All-Gender) and right-zip (Women's) bags can be mated together, allowing you to share warmth with a tent mate.
Interior loops are provided to securely attach a liner for added warmth (liner sold separately).
Exterior loops are included for easy hang drying or storage when not in use.
