Currently using a Filson Small Carry on Bag as the "man bag" in the field. Carry camera, binocs, small first aid kit, fly boxes and miscellaneous junk. Having issues with the zipper to get in and the straps for opening and getting camera out quickly, also very loud with the straps and brass pieces. Question-anyone use something different? Would like to stick with Filson, staying away from backpack due to ease of access. Interested in the Tin Cloth Field bag, similar to what I have but no brass and leather. Issues? Others? Thanks for any comments
