This is a lightly used, men's size Small NeoSport Sprint Sleeveless Triathlon Wetsuit. I am 5'11", 145 lbs. and this wetsuit fits me snugly, but well. It would fit anyone 5'7"-5'11" and 135-150 lbs. It has been used less than 10 times and rinsed after every use. There are no tears and it is in excellent condition. Selling because I have a full wetsuit I prefer to use. If interested, email or text 203-962-4261.
