Love the stretch on these shorts. No pinching or awkward seams and I can bend, run, or sit without any problem.

I’ve been wearing these under my work pants and I’m happy with how they don’t show under thin fabric. So comfy!
Allison P.
I wore these during my daily walks and definitely sweat more around my waist. Still felt comfortable and they never rolled down.
Michelle B.
I was looking for something not bulky under dresses and found these! They keep my belly looking flat and I don’t sweat too much.
Monica T.
I wear them under my dresses whenever I go out. No lines, just a nice shape and I don’t get too hot in them either!
Emily D.
Smooths me out under jeans. Love the fit.

Best thing for making clothes fit smoother! I wear them under jeans and dresses. I always feel more confident when I have them on.
Riley Q.
These sauna shorts kept me dry during school runs and errands. They hug my waist nicely but don’t feel tight.
Tyra G.
The shorts hold everything in nicely but don’t dig into my skin. They’re soft, almost like wearing leggings, but with more shape.

I was surprised by how lightweight these feel. Perfect under skirts for work, and they stay fresh even after washing over and over.
