HALF TRACK PRODUCTS SACKTOTE C/black (Cordura Black) The nonsleepcushion is convenient, but it's not very practical outside of a car. So, I wanted an item that could be used as both a stuff sack for a sleeping bag and a bag. You can attach it to other bags with the side loops, and it's also very convenient for bike packing. Not only for sleeping bags, but when you pack things like a change of clothes, you can easily access the bottom from the side zipper. This is a used item, so no claims and no returns, please.
