Our Women’s Greystone mummy-style sleeping bags deliver high value and performance in a lightweight bag. Ideal for backpacking but versatile enough for couch surfing, they are insulated with DownTek™ and use baffle construction for efficient heat distribution. If you’re in the market for a mummy shaped bag constructed with high quality, lightweight materials these bags are your ticket to getting out there in comfort and warmth.

Our Verdict

Womens Greystone 20 Down Sleeping Mummy Bag is designed for women with a generous mid-section, yet narrow at the feet to avoid cold spots within the bag. 625g of Down Tek™ will repel moisture therefore maintain insulation value even if it gets damp. With a fill power of 600 the Greystone 20 has a Comfort limit of -7°C which is a good warmth to weight ratio for bag weighing just over 1kg, making it highly transportable.

The ¾ length 2-way zip is ideal for easy access and allowing a heat dump from either the top or lower sections of the bag.

Single hood baffle, padded collar and ‘no-draft’ zipper, keeps the draught from seeping throughout the bag.

The distinctive dusky-rose colour is unusual and is paired with a practical dark brown lining and yellow zips.
