      Spring suit

      True to size guide in both hips and chest. The leg length was slightly longer than expected for a medium / short but more warmth.

      Quality material and construction. What I expected from this company.

      works well for lake swimming

      Bought this for my husband who has started open-water swimming in the summer (in Minnesota). He is 6'2". We used the size chart and got him a 2XL, and it fits him well, although there's just a little extra fabric in the neck and chest area for him, so I think an XL would have fit him as well. Still, he likes it and it's functioning for his purposes!

      Better than expected

      I wore it in my pool the other day because the water was cool and a cool breeze was blowing even though it was sunny. It fit snug and once the layer of water warmed, the suit was perfect. I have 4 other full suits and this fits the best of all of them and is the most comfortable. This is not just a good Spring suit, but also fall for late season pool use.
