Ideas for SUP wetsuits has great Fusion neoprene bottoms but the usa customs makes purchase expensive. Anyone know of a usa outlet for wetsuit bottoms? ~2 - 3 mm.

wetsuits sometimes has good deals on wetsuits.

Check surfing suppliers – the surfing suits are often more flexible than the ones commonly sold for paddling.

I go with Oneil Shorts 1.5 mm
I really like my Oneil Hammer Shorts, I wear them a lot in cool conditions.

Not much I know of in the way of long wetsuit bottoms.

NRS sells 1.5 mm hydroskin bottoms. I have a hydroskin Farmer John, it’s better than nothing but not very warm. I suspect I would be as warm in my Oneil shorts as in hydroskin bottoms…
