Cpmpression bag for big fluffy items
This is a large compression stuff sack that is strongly made and easy to handle. I'm using them to compress down large sleeping bags and fluffy jackets. Like most products from OR, it is high quality.

Throw away your old stuffsack
This compression sack is super lightweight, and even stuffs inside itself for easy storage. The material seems robust and the product is well made. It can take some practice to pack it efficiently. Be sure to alternate on the compression straps. My biggest gripe with the product? Ordering the right one. Be sure to check your sleeping bag or ten's volume before ordering. I had a average sized mummy 0C sleeping bag, and it ended up fitting the 15L perfectly. Recommended over the manufacturer specific bags!

Awesome Bags by OR!
Had some sleeping bags lying around without any proper storage. Bought 2 of these compression bags (25L and 35L) and they work perfectly. Nicely built bag, easy to use. I am planning on getting more.
