I am about to purchase a new pair of waders. I have always had 3mm Neoprene waders but I am considering 5mm. What do you guys suggest? I do all of my hunting in Texas and do some public hunting that requires a healthy walk in. My 3mm waders turn into an oven pretty quickly on the walk in and I didn't know if 5 mm would be unbearable.

Breathable! 5mm in Texas surely can't be good

I think you just answered your question...

Unless you always hunt standing water, most can get away with breathables all year in TX

I really dont think 5mm is that much warmer than 3mm, just more durable. Neither breathe, so both will probably be equally hot for your hike.

3mm

no way I'd have 5mm and I hate the cold but hate a sweaty --- even more

Between the two, definitely 3 mm. I use breathable all season here in the panhandle. Neoprene are way too hot for any kind of walking!

I like the 5mm...they will keep me from looking like Ralphies brother.

I've got 5mm and am never incredibly hot. They are heavy though, and I wish I had the breathables for the long hike ins.

I have 5mm, but my next pair will be breathable.

I like 5mm waders, they seem to be tuffer material, I never really get hot but don't have a lot of natural insulation (body fat) either.
A buddy that is a little larger can not stand neoprene at all because they get to hot for him.

Breathable- and never look back.
You can always layer up with them, and they will last.

I have canvas, 3mm and 5mm. Different situations call for different gear!

3mm

5mm is too much for North Texas. I bought some at Mack's a few years ago and rarely wear them. If I had to do it all over again, breathable 3mm for sure.

I carry my waders and put them on after i cool down from the walk. I have both thicknesses but only break out the heavies if its super cold. Walking in either kind is too hot for me.
