Women's HO Full Extreme wet suit; not sure the MM's but not good for ocean surfing (too thin). Purchased from a waterskiing/wake boarding shop. I used it for triathlon training and swimming across Elk and Thetis Lake. Says size 9-10 but fits small. I was 5'7" and 135 lbs, so about medium sizing, probably size 7-8. This is a great suit if you are just trying out triathlons, keeps you buoyant! Or maybe for SUP stand up paddleboarding! Cross posted.
