Me too. Totally agree. My Simms Guide Chesties finally got retired as one stocking foot has a very slight leak , they lasted 25 years and probably used 60-70 days a year , at about £500 at the time were a big spend out , but 25years use makes it money well spent. I have them in the kit as a spare just in case. ButI have a set of Simms G3s now which are a bit better fit and if I get that amount of use out of them I’ll be well happy. Just have to hang them up to air after every trip and tech wash every now and again to clean them. Shame the Simms wading boots aren’t as good though. I’m on my 4th pair of cleated ones , trying Patagonia ones to see if they’re any better.
