My daughter has tried a few different tech suits but keeps coming back to this one. We have not tried the speedo pure intent because she likes this one so much we haven't felt it to be necessary to spend the extra $$. She is 5’7” and about 110 lbs and is built very lean, with narrow hips. We get her a 24 in this suit. She wears a 26 in Jolyn suits for ref. She says she feels good in the water, sleek and compressed but not too restricted to stretch out and get good reach. And the straps provide some give so they don't cut in. The sizing chart is very accurate but she is in between (or crosses over into) two sizes. We did try a 23 but the time and tears it took trying to get it on weren't worth the extra compression. We spend only about 10-15 minutes to get the 24 on her (narrow hips and butt making it easier I'm sure! ), and she can do this by herself if need be. We have noticed it doesn't seem to repel the water like the TYR out of the box (in the sink test), but she had some very big drops in all her events last time she wore this said she didn't feel like it was taking on any water. She also likes the cut and seam placement of this suit better than some of the other suits for her body (she doesn't like when the seams cut across or hit at the top of her hips), and this is the easiest to get on her, out of the other brands/styles we’ve tried, so that is a big factor honestly. We still like other suits and she is always excited to try something new, but this is the one we go…
