Fourth Element SubX scuba diving undersuit XXXL Very Warm

This is a two part XXXL Fourth Element SubX undersuit - salopettes and jacket - at the time the warmest undersuit that they made. I've marked it as "used" - but I think I "used" it once to try on under my drysuit and didn't actually dive with it. Mint condition other than the buckle on the waist cinch which has some corrosion on it (see photo). Not sure how - the suit's been kept dry in a cupboard since I tried it on. I'm not sure of the exact measurements, but when I was diving I was 44" waist and 6'7" and it fitted comfortably.

It's fairly bulky - designed for long decompression dives and ice diving under a membrane drysuit. I think you'd struggle to fit it under a neoprene drysuit.
