Hooty,

I have a Catalyst and have only used it on up to 4 night hikes with the expectation of doing longer trips in the future. My budget is limited so I needed a do it all pack. One of my favorite things about the pack is that it's not over-built and I don't feel as if I'm carrying too much pack for the trip. To take up extra space, I double bag my sleeping bag in two trash sacks and allow it to loft up in the inside of the pack. Cinch the compression straps and there likely won't be any rattling or jostling. For overnights, I even take the single stay out of the frame sheet.

I hope you enjoy the pack as much as I do.
