I bought this because it was cheap. it worked at about 43 degrees water temp but was a little cool. would not recommend any lower. but above that you will be fine. P.S. My drysuit flooded with the 43 degree water and i stayed warm enough to continue the dive.

Recently bought a drysuit and did not expect that undergarments were so expensive! Did a little searching and found this one, which seems just as good as a $200 undergarment. I paid under $60 for this (including shipping) and it arrived in just a few days (shipped from the UK). Nice and thick, which should be great in California waters, which are typically in the 50's at depth. My only gripe is that I wish the zippers were covered to prevent chafing the inside of the drysuit. It has heel straps and thumb holes for donning. Double zip, so you can just unzip the bottom to relieve yourself, or attach a P-valve.

I call it my technical onsie. I welcome winter.The center elastic piece is a bit frumpy, since it's high over my belly. Probably makes sense for it's intended use under a wet suit? I do wish it fit a little better around the waist. I don't use it with a wet suit. I use it to work from home when it's cold. No complaints on the stitching and quality. I'm 5/10 150. lg fit fine.

My husband uses these for scuba diving in cold water under a dry suit...so far in 36 degrees they kept him warm.He's very happy with them.

Great for using under my dry suit. Very warm even on deep dives! 😀

I'm 1.78m, normal body size and took the S size and it's quite wide, almost too much. Besides it feels warm so it's fine for me

Ho dovuto accorciare un po' le estremità in quanto la taglia S é risultata un po' abbondante sotto la muta stagna. Per il resto rispecchia la descrizione

A good medium fit, although a little long in the leg.Appears well made, and the only thing stopping it from the extra star is the lack of a smooth patch on the left upper sleeve to stop the drysuit valve being blocked.

Gul do them selves no favours with their ad-hoc sizing - supposed to fit under a wet suit? - so much material I could fit two people in to their Radiation Drysuit
