TYR Sport Men’s Category 1 Hurricane Sleeveless Wetsuit

I have used this for lap swimming through the winter; it kept me warm down to the low 60’s for prolonged (40 mins to 1 hr) swimming. However, the sizing is off, I had to get another one to fit properly.Some observations:1. I am 5’5″ male, not obese, fairly active. On their sizing chart, that makes me a MS (medium small), which I bought. This was WAY too tight. I can get it on, but the shoulders didn’t fit, and after about 3 mos the zipper finally broke from the pressure. (two teeth popped out). I have little tears that I could repair, but they were from my fingers when I was trying to pull the suit on.2. The medium fits me better! No tears, and it’s reasonably tight.3. Even at the right size, the suit is a little stiff for doing butterfly/breast stroke4. Doing freestyle with this is crazy, you swim a LOT faster not because of buoyancy but the increased stiffness in body roll and reduced resistance. I have been able to swim a little the past couple of weeks without the suit, and I feel like someone put a cinder block on me!Overall 4/5 because it’s great with the right size.
