I legit love these leggings.

At first, I was skeptical as to how these leggings would fit, as I wasn't sure how the built-in underwear would feel. I also didn't know how the quality would be, as I had never shopped from here before

LET ME TELL YOU: I can hardly feel the underwear, and these leggings are butter smooth, AND THE QUALITY!! IS AMAZING!! They are now my new favorites to travel in and run errands in. There are no underwear lines, and all of my friends can't believe that they come in with built-in underwear! I have recommended these to everyone I know.

I am medium height, and the 21" is the perfect fit for me. I would recommend these if you are on the medium / shorter side!

I love Meira Active and I will continue to purchase from this store!!

Excellent leggings!

Happy I splurged, worth it!

Keep it smooth

We got rid of your underwear's side seams and vertical back seams

Why you'll love this

You're a human who moves

Shaped not to interfere with how your body moves, our built-in underwear acts as a lining to offer another layer where comfort is key. We always make sure there is no bunching or riding up. Next to weightless fabric is fit to stay smooth over your shape.

We do your work

Good news - we picked out half of your outfit! Your leggings and underwear are already paired. You will not have to search the laundry pile or drawer again! Usually go commando? You'll be truly impressed with how you'll still have that unrestricted feeling yet reap the benefits of another layer as weightless as it may feel!
