I received the Pro version as an ambassador and was really happy when both tall and short fit into my 65L Osprey Ariel pack and would also allow space for my tent on the side. I fit both my clothes and jetboil inside the large one and at night I put my down jacket into the short pack for a pillow. I love that it's waterproof and will keep my clothing dry.
As a Hillsound ambassador, I received the PackStack PRO (both a tall and a shorter) for testing and feedback. They stack just right in my Arc'teryx Bora AR 63 backpack, and the short also fits perfectly in the top of my camera travel backpack. They also fold down quite small when not in use. These are definitely going to become my go-to birthday gift for my active friends.
