Volcom 1mm vest is perfect for summer. Keeps the chill off without the chaffing of a long sleeve top. Size is XL. I wore it just a few times, and always rinsed and hung to dry. Retail is $50-$70, I am asking $30.
Also for sale:
XCEL SLX 2mm short sleeve fullsuit size large short. Also word just a few times, paid $130 asking $95.
