I received my Broadwing bag from Seek Outside to run on the Revolution frame/suspension. I was hoping to run the Broadwing similar to how they show the Brooks pack with the main bag compressed and just the 2 outer pockets for gear while day hunting. I thought the upper split pockets could be completely closed off with zippers or similar, but that is not the case. The pockets have drawstrings on top and bottom that reduce the size of opening, but do not fully close the pocket. I didn't order the Brooks because I already have a Revolution and wasn't sure if the Brooks would work with the Revolution. I have contacted SO about the Brooks and Revolution compatibility and will update this thread when I hear back from them. Or maybe Kevin will see this and update. I still think the Broadwing is probably a useful and well made bag, but not for my use. I just wanted to get the info out to those who were looking into this bag, since the info is not clear on the website.
