You're going to get a yellow one.... Aren't you?
i'm not cool enough for yellow, hipster.
Thanks for the info here, gentlemen.
I'm reasonably set on the sagebrush of similar. A roll top is a bit of a pain, IMO - a bit slower than the zipper, though a nicer opening..... may end up with that if I can't find a sagebrush. it's certainly cheaper!
as for the zippers waterproofness, I trust it. it's the same as the one on my drysuit and neither have failed me yet!
btw, those Tzips work a hell of a lot better with a big of silicone lubricant. Dow Corning 111, tzip lube, ky jelly. whatever you have laying around. the latter not interchangeable with the former....
