Great for minimizing the load
I bought one of these stuff sacks a couple of years ago for a sleeping bag I had just purchased. Whether I'm backpacking, car camping or just road trip traveling, I like to pack and travel efficiently. This sack is just what I needed for a sleeping bag. Although the guide that comes with these sacks suggests the largest, size 30 for sleeping bag storage, I bought the 20 and it packs my bag down nice and tight and firm. I don't think you need anything bigger for a sleeping bag. This sack is small, but don't let it fool you, it WILL pack your bag. So far it seems very durable, with very strong seams and closure cord. I just bought a second. I'm very satisfied.
Quality, inexpensive stuff sack!
I ordered this to store and transport all the parts of a 60-foot slack line (mainline webbing, slings, carabiners, and rappel rings). It fits all the gear with room to spare (I got the 10 liter bag) and I am very happy with the quality of the material. I like to keep my gear organized and with all the parts of the slack line in this one compact bag, I can easily just throw it in the bottom of a backpack when I go hiking or camping just in case the urge to slack hits.
I plan on putting together a couple of slack line kits for people for Christmas and will definitely be ordering more of these bags.
Best for the price!
Just got a few more 10L and 15L REI stuff sacks. They have been proven in the backwoods for many years. These things are great for backpacking. I use them to organize the inside of my pack for perfect weight distribution and quick access. They also make great laundry bags as they don't leak or retain scents easily.
Does the job
This is perfect for storing mid-weight cool weather sleeping bags. I opted for the larger size as I need them for storage, not backpacking so I don't want compression. They are a heavier-weight fabric than I expected (a good thing) and look like they will hold up over time.
