Material for UL fishing waders

Forgot one other thing… what is going to be the right process to seal seams? Of course this will depend on material chosen, but is basic seam sealing an option or will a seam tape be necessary?

This discussion might be relevant to you.

Yup that’s def the same thing I’m looking to do. Looks like we had a lot of the same questions. Other than suggestions of products to buy though, I don’t see much info about materials and process.

so I’d still love to have a rough minimum head pressure for waterproofness if anyone knows it or how to determine.

Seeing how your going to be standing in water with them, I can’t imagine you’d want any level of breathe-ability. Something like a thick cuben fiber would be lightweight and completely waterproof.

I have a pair of those Wiggy’s waiters for stream crossings. They are a lightweight nylon type material. When you step in the water, the fabric suctions itself around your legs, unlike the thick rubber ones, there isn’t a single bubble of air between the material and you.

Yea, I don’t quite understand the science of how waders “breath” underwater, but in my experience, they sure seem to. I’ve been fly fishing for 6-7 years in a pair of mid-level Simms goretex chest high waders and I’ve never felt clammy or more than a tiny bit sweaty in them. As I said in the initial post, if there is a WP, non-breathable material that is substantially lighter and cheaper than the WPB options, I’ll def consider it. But figuring out the actual options (defined by quantitative waterproofness, durability and breath ability numbers) is my main goal and anecdotal info isn’t really what I’m looking for.
