I will never buy a different sleeping bag!

Use this in my role as Scoutmaster. Absolutely love it. Look forward all day to climbing into this bag and shutting it down. Coziest I have ever been.

Greystone 20 Long

Just finished a 3 day gravel ride in the Blue Ridge Mountains in Virginia. Glad I had it! Had two cold nights camping and was plenty warm. I am 6'5" 195lbs, and had plenty of room. Only issue was figuring out zipper when I unzipped too far, but figured it out. Had it strapped to handle bars in light weight dry bag, pack down small and was plenty light.

Enough room to move around and a great price!

I've been enjoying the nights I've used the Greystone so far. It's been a long winter here in Utah so the early spring trips have been colder than normal. I've been happy with the performance of the bag so far. I have used a liner when it's got into the 20's overnight to help me be warmer. This bag is best I think as a comfort rating more closely to freezing and warmer. I like the design and the fabrics and the ease of getting in an out. For the price point, BA definitely has a great option here.
