Even though my weight (133 lbs) and height (5' 9.5")qualify me, according to the size chart, for the next smaller size, the WML is REALLY snug. My arms are pretty slender, but the arms of the WML are very skinny! The narrow shoulders smush my small chest and restrict my movements, but once I start swimming, it's comfortable. Taking it off is difficult, as it's hard to peel off the bottom half of the legs. I think the 2 layers of rubber rub against each other. The ankles are very narrow. I wear a rashguard underneath it to facilitate removing the top half. This thermal design keeps me warm for 2 hours plus these days, in Maui's winter ocean. My older Blue70 thermal suit wore out in numerous places around the waist and hips and permitted water to enter that way. I was NOT pleased with its short life span (I wear it about 6 months of the year; after 12 months of use, it had numerous perforations and frayed areas. Sitting down on lava rocks as I prepare to enter the water was no doubt one of the causes. But as I mentioned before, I like this company's vibes!
