Trust me ECWS works in the wet.
It is not designed for the civilian marine environment, camouflage and boating is not usually a smart mix, but surplus is a good/cheep alternative to get a set of Gore-tex'
I googled it but didn't find anything that had anything to do with water, but that's because it's an overwhelming search. All kinds of unsuitable stuff is mixed in with whatever you are suggesting. If I add "water" to the ECWS search, I get a whole different subject matter entireley. The little surplus looking ECWS I did find was as highly priced as the retail stuff. They must have seen me coming. Maybe I don't know the right nomenclature for what I need...
Totally not the intended purpose, but I have used my polypro under my wetsuits. It works great if not a bit bulky but not as bulky as a drysuit. Soaking wet, snow on the ground, still very warm.
I have a set of polypro from the army. It's very bulky. You wear that under a wetsuit and you get it wet?? My wetsuit is skin tight, I'd have to buy one 2 sizes larger to even try to get polypro inside that suit. And you get it wet??
The boots are 5 mm neoprene - like heavy dive boots. On our trips my feet are always wet. Everywhere we launch requires some wading. I have pretty good circulation in my feet, so with a little water in the boots, they stay warm. The way I look at it, for 25 bucks it isn't much of a risk to try.
Ok, sounds good. I already have a pair hidden somewhere in the house, so I can try them for free, I hadn't rembered you have to get them wet to get in the boat anyway...
