PROBLEMS
So difficult finding
the perfect pair of underwear.
It's my baby's first underwear but I'm not sure which one to get.
All the underwear I found doesn't fit my baby.
They're wearing their size but keeps saying it's too tight.
They don't like how it feels when they have it on.
It's difficult to find the right size with other brands.
Bought it thinking it'd keep them warm, but they're compaining it's hot and uncomfortable.
WHY WE MADE

Heart of Every Parent

I tried to buy my baby's first underwear, but realized it's a bit different from buying clothes. I felt lost. My baby transitioned from diaper to underwear pretty early for their age so it was difficult finding the right size.

I thought cotton would be best, so I bought 100% cotton, but after raising two kids, I felt like cotton wasn't the answer. Since it's their innerwear, they have to wear all year round - the material had to be thin, breathable, and snug-free. I learned that material is key.

I've added my experience of raising two kids into the quality of this product. Our Premium Modal Fabric makes it perfect for your child's first pair of undies. We've made it so that it can be worn as early as 25 months. No need to struggle any longer to find the perfect pair of underwear.

Soft and Colorful

Ordered during potty training, so soft and nice! The colors are pretty too! My child seems to enjoy wearing them, perhaps because of the soft texture! [Translated from the official Korean website review]
