Xterra Vortex wetsuit, perfect for open water swimming/triathlon. 5mm from neck to ankles, back is 3mm, sleeves are 1.5mm-- super comfortable and gives a full range of motion. Size is meant for anyone 5'5 - 5'9, 140-150 lbs and can fit both men and women (I'm a 5'10 woman and it was a good fit). For an extra $50, I can throw in booties and an insulated swim cap, also both from Xterra. Worn 4-5 times, is in near-new condition. Original price is $249. Pick-up on campus.
