It's IN the stuff sack?
I love pulling this little thing out and letting people guess what it is. It compresses down so small that there is no way anyone recognizes it as a backpack. I use this for throwing beer, sunscreen and a towel in when going to the beach or a Frisbee, water and dog leash when I take my pup to Tanner park for an hour or two. If you plan on filling it all the way up you need to get a bit strategical with it. You can't just start throwing things in or it won't rest on your back comfortably. All in all a super solid pack for what I ask of it---oh, and did I mention it sheds water?
