These core shorts actually fit a curvy triathlete. They are thin enough to wear on all swims but give just enough buoyancy to help with my body position.
I went by the sizing chart but this is too small; I will purchase a larger size.
I wear these for part of my training in the pool. They lift my hips just enough to notice a difference. I definitely like them, but wish they came up about another .5 to 1 inch on my waist. I have a high waist, so I feel like they are falling down. They are still just effective. I'm 137 lbs 5'7" and I have these in a large.
Comfortable, fitting and light, have tried other brands, these are the best!
Love them. True to fit! Easy to get on and helps lift the hips without wearing a full wetsuit. Highly recommend.
