I'm surprised nobody busted my nuts for shit-canning the Canadian buttons. I really love them, but I figured for cold weather ops, with gloves and mitts, this might be the easiest way to get in and out of them. Also wanted to streamline the top flaps a little bit.
In a past millennium I thought the buttons were cool. When I had the chance & $, I ordered one in OD- with all the works & jerks: pocket D rings, interior pockets...and taped large buttons. With the pockets & the poachers in particular, some of the slivering activities could be done with out webbing.
So I tried it. Tools, consumables & water went well. The big buttons were a bust. Every bit of wire, thin cord or vine found them. One even got jammed in a crack or rock gap and had to carefully cut off.
