Here's the skinny. Simms are made in Montana. Check. These headwaters are gore-tex. Check. They are anatomically cut, have super tough reinforced lower legs, thinner but tough neoprene booties, and a really cool micro fleece lined hand warmer pocket. Check, check, check, check. Another sweet perk lies in the leak detection department. If you have a pinhole leak, you can blot rubbing alcohol around the suspected area inside your waders, and the waders will appear black around any leak area. This prevents having to fill the waders full of water to look for a leak, which in turn stresses out all the seams from having gallons and gallons of water weight in the waders.
I really like these waders after a few months of use. I feel confident bush whacking through the woods with out worrying about ripping the waders due to the tough "chaps" on front. I love the way the fit too. I'm 6 feet with a 33inch inseam and size 10 1/2 foot, and these fit like a glove. I don't know if I would spend $300 on any pair of waders (that's just a lot of money), but I feel good about the $190 on I spent on these. They should last a long, long time.
*After a year i still dig these waders and the are doing great! 1-4-2013
I know, gear reviews stink compared to pictures of fish. I'm going fishing Tuesday and hope to have a good report with good pics. Salivate.
