I just bought a pair of Ft Thompson's a couple of weeks ago and have only worn them five times, but dang I like them. No leaks and very warm. I asked the lady helping me who makes theirs and she told me Itasca. 5mm, 1400g, great pockets...shell loops, wader belt, velcro and snap buckles on the shoulder straps, Natgear. They have a strip of sealant on the inside of all the seams. Ft Thompson has a website now if you want to check them out. They're just like Mack's.....the logo is the only difference.
