Hands down the most comfortable underwear ever designed for girls, our Bella Briefs are crafted with ComfySeam™ bonding technology. Instead of being sewn together, our super soft tri-blend fabric is fused together using advanced adhesives—bringing high-end sportswear innovation to kids undies for the first time.
The result is barely there seams that are practically stitch free, except for a couple of minimally stitched areas for reinforcement. The Bella is soft and smooth, with a fit that is absolutely perfect every time. As one of our little reviewers exclaimed, “It’s like wearing a cloud!” We couldn’t have said it better.

Finally, underwear she will wear!
I went looking for no-sew seam underwear for my daughter (similar to some Patagonia underwear I own) because she is very sensitive to, well, all sorts of things. These are the only ones I found. She will wear them without doing all sorts of stretching out maneuvers on them beforehand.

Love these for my little one
These undies are well made! My 3 year old daughter seems to be allergic to thread at the seams on the legs. She was constantly itching and wanting to take her underwear off.I had such a hard time finding any that didn’t have that! Once I got these she felt so much more comfortable! I’ve washed them several times and feel they’re great quality and worth the price. I ordered another 2 pks right away.

Soft and Comfortable
My granddaughter loves them. They stay put and feel so soft.
