DOREEN E Purchased for trip to Mount Kilimanjaro. It was suggested in several articles to stow a sleeping bag. It was perfect for my new Mountain Hardwear Lamina 0 sleeping bag. I was concerned about keeping the sleeping bag dry and with compression. This product was great! It costs a little more then the other compression bags but I would say it was well worth the piece of mind and ease of compression. Ended up buying a second one for my Mountain Hardwear Down Jacket.
