Big Agnes says: 

Our Greystone 30° mummy-style sleeping bag delivers high value and performance in a lightweight bag. Ideal for backpacking but versatile enough for couch surfing, it is insulated with DownTek™ and uses baffle construction for efficient heat distribution. If you’re in the market for a mummy shaped bag constructed with high quality, lightweight materials this bag is your ticket to getting out there in comfort and warmth!

Our Verdict

A warm and cosy down bag that goes a long way to reduce cold spots and drafts from entering the bag.It’s a generous-sized bag with plenty of room to toss and turn without the bag feeling constrictive. The Greystone has a nice well-fitting hood, an oversized interior anti-draft collar and an insulated tube along the hood, which all increase the bag’s warmth, and prevent cold air from entering the bag.

Its good for warm weather camping hear in the UK but I wouldn’t want to push it to far past its 3°C comfort limit.
