DrHolds two adult-sized sleeping bags easily. Only complaint is the clasp that holds the draw string closed is weak and allows the stuff bag to open on its own.Use it for sleeping bag covers. Could have been just a wee bit bigger, otherwise they are very nice covers that fit snugly.Had some waterproof sacks from Outdoor Products that were sized as width of opening (basically half the circumference) by length. Kind of a strange measurement for a cylindrical sack, but okay. So I ordered this (with two undeclared dimensions) based on that and got a sack with the diameter by length. Now those sizes were what I would normally expect, but experience showed something different--and so this sack is now waaaaay too big. Oh, and by the time I got back from the Boy Scout trip and caught up, the returns period had passed. :(This Bags Is Useless For me i am Expecting more bigger bags than This for my Sleeping bags. I need size Double than This 20 in weight X 40 in Long.so i need to returning this.I’ve been using an oversized fabric bag to store my down comforter for the summer months. It was cumbersome and takes up precious shelf space. This bag fits my comforter like it’s custom made for it. You’ll need to roll (it’s called a ranger roll) the bedding to make it fit.loved stuffing my sleeping bag in this new bag. Bag felt durable and just a dash bigger than my original so it was easier to stuff.There I was, without a bag to stuff my sleeping bag in. I bought this, and now...BAM...I stuff my sleeping bag into it! Problem solved.
