We needed this as a practice suit for my daughters first swim team experience. She loves it! It is perfect- very comfy, fits exactly as sized, and is super cute. Her competition suit took multiple orders to size and is really low in the back, but this one is a fave! She loves it enough to be her summer suit, so that is a win too.

5 Stargazer08
I bought this a couple of weeks ago for my daughter. She absolutely loves it. She says it is the most comfortable swimsuit she has had in a long time. Also, the price was right!

5 sarahfaith2001
My daughter loves this suit. Fits her so well. Would recommend to others!

5 CoastalFan
I bought this for my daughter for her swim competitions and it fits great and stays in place. It has not faded at all and the Nike logo has not peeled at all in the chlorine water.

This will be used for putting docks in the water in the Spring. Definitely seems like it will keep me warm. Fits ok for a guy that ’s a little under six foot, two hundred pounds. But it seems a bit cheaply made. The padding on the knees are not very thick and there is a little tab of velcro at the top of the zipper to prevent the zipper from working it ’s way down. It ’s not really needed because there is the velcro mock collar tab above the zipper on the neck that already covers the zipper. I ’ m going to remove it

4 Senior Rex
Very happy with this purchase! Bought it to wear kayaking on hot days while the water is still chilly but calm. Love the fit and the stirrups at the feet and finger loops at the cuffs make it easy to wear as an undergarment while keeping it in place. Great suit!

Great quality singlet. Material is nice and thick and will lasts. Looks great too. My only issue is that the bottom where the legs come out is a elastic scrungie type where its ruffled at the ends and not nice and smooth like it is in the advertised photos, but honestly not a big deal. Would definitly buy again.

5 ladygideon
I ordered this maroon colored singlet in a hurry for my first olympic weightlifting meet. I felt other brands looked a little nerdy online. This one by far looked better and liked the color it was true to image seen online. Loved wearing this! super comfortable. I liked that it did n't rise in the legs during lifting. Seems to have some reinforced elastic to prevent this. Since this was a men's singlet I wore a compression like shirt underneath for additional coverage in the chest area with no issues. This is advertised as a men's singlet but worked for me. I even had several compliments from guys. lol! I will say that I have a long torso so there was a little pull in shoulder to waist area but did n't bother me. It's possible a medium would fair better. Hard to say when you ca n't try on in a store. Great product. would recommend.
