Granite Gear Round Rock Solid Compression

lightweight, durable, effective. couldn't ask for anything more in a compression stuff sack. 

I have used one for several years for sleeping bags and loose clothing on trips. the top and bottom are fairly robust nylon, the body of the bag is a crinkly lightweight ripstop.

this has been squashed into backpacks a lot, yanked tight, and it is as good as new — not a hint of stitching failure anywhere, no abrasions on the nylon bag.   

The best there is, if you want organize and make room in your backpack. They are indeed rock solid and well stitched with sturdy buckles and straps and rip-stop fabric. They are even getting better; newer ones are waterproof.

As the commercial says "don't leave home without them."

These are the absolute best compression sacks on the market. I use them for my sleeping bags and my clothing. They make packing my pack so much easier.

Own several of the sizes. I can color code my contents.

I use these to organize and compress my sleeping bag and my clothes. They're much easier to use than a stuff sack, and they really reduce volume (by about half for my clothes and even more for my down sleeping bag).

Tighten up your load with these!
