This is a great companion on the trail and it feels weightless in your hands. The fleece is nice but the best part is the sac is cut to be flat rather than round and if you carefully fold what ever you stuff in it you will have a large area to use as a pillow rather than a small spot when using a regular stuff sack. The wide flat shape accommodates any tossing and turning while you sleep.
All granite gear products are made with exceptionally high quality so purchase this sack with confidence.
Stuff this with a jacket and went right to sleep. It was a touch smaller than I expected but that is my fault for not ready the dimensions carefully. It does its job and is less noisy than a regular stuff sack, as a pillow.
