I have about 25 of the same wetsuit. They are Mar-Vel International branded. All spring suit with long sleeve. All size men's small. All new condition. No markings as far as the thickness of the neoprene, but my educated guess is 3mm on the torso & legs, and 2mm for the arms. Selling for $45 each, would LOVE to get rid of all of them at once. Definitely willing to do better on price for bulk buy. Hoping someone has a ski or wakeboard school, or diving school that could use them. If you know someone interested send them my way!
