I recently bought a Seek Outside Fortress 6,300 which is the Revolution vs Integrated line (Unaweep). There are so many reasons I think it is an excellent pack. First, it is made of X-Pac and doesn’t have a main-bag zipper so it is waterproof. I don’t miss having access to the main bag because there is the Talon back pouch and I chose to add a top lid and side pouches. Everything I need is easily accessible without having to get into the main bag.
When I go on day trips or an overnight, I almost always bring my SO Fortress 6,300 because it rolls down into nothing. I also have a ZPacks Blast and a McHale SARC along with a few others. If I had to do it all over again, I’d buy the Seek Outside and use no other pack. Moreover, I haven’t used any other pack since getting the SO.
I would also get the Revolution line as it allows you to remove the bag and use the frame or other bag as a hauler of wood or other items. Otherwise, you’d be hauling wood inside your main bag which may compromise it. Also, you could get the Fortress 6,300 and then separately buy the Peregrine 3,500ci bag and swap them back and forth. The Revolution bags are removed and exchanged easily. You can do the same with the Integrated line but is more involved.
I’ve had some very nice backpacks but nothing as comfortable and as able as the Fortress/Unaweep.
