Just right - Cocoon TravelSheet - Microfiber

The opening is wide enough to get in and out of easily rather than being just a tube. Spacious. I just this one instead of the mummy shape for it to be more versatile—I can unzip my bag an kick legs out a bit while still inside liner to block drafts, I also like it full size to fill dead space in my mummy bag (useful for cold nights). Purchased this with the intent of prolonging ht life of my expensive down sleeping bag.
