My stats, although estimated, are somewhere in the order of 3.5 years with an approximate number of 224 times donning one pair. That is based on pulling up the waders on Sat and Sun half the weekends of the year (26x2 = 52) plus 12 additional days where I sneak in some fishing thru the year (dedicated trips, weekdays, Spey casting mornings, etc). Then multiply that by 3.5 (3.5x64=224). My wife would argue that's low, so I'd wager it's pretty accurate.
Yes I've had leaks, and patched them once, and I have a slow leak on my left knee right now. Worth the price? Well they are pricey but I would wager that only the OS Systems non-breathables could give me a better value but could not provide nearly the comfort because the OS do not breathe.
I've asked for a new pair for Xmas and noticed a suspiciously fat garment style box in the closet
Count me in the Simms guideweight fanclub!
