Your pocket is the stuff sack... I have a Granite Gear and a LL Bean Shell (Breathable Rain Jacket) Both came with a stuff sack. So I never looked to try this. set aside the stuff sack and turn the main pocket inside out. Then stuff the shell all the way into the pocket. Now that the zipper is inside out use the pull to pull it closed. Even if this is a mesh pocket it generally works and now its in a small space and you can leave the stuff sack at home. The LL Bean has a key ribbon that is sewn in, and that becomes the carbine-er attachment to hang it outside the pack.

Hey in both cases this was NOT in the instructions.... So you got to try it!

The more stuff sacks you can leave behind..... Yea!
