Review on CtriLady 2Mm Neoprene Women'S Wetsuit Leggings With Pocket - Perfect For Snorkeling, Swimming, Surfing, Canoeing, And Diving by Jim Moody

The Neoprene fabric is good and thick, I was standing in a 55 degree room and was only a little chilled. Probably will be appropriate for lukewarm-to-cool water exercise or chilly dry exercise. I ordered the XL for a little extra room, my hips are 40", so if you need it for swimming make sure you get your true size so that they work properly when wet. I put a 6"x3" chocolate bar in the roomy pocket to show what you can fit in there. Drawstring at the top and stirrups at the bottom help keep pants in place, and they will definitely trap warm water when swimming since you can feel suction around the hips when you do squats.
