Despite being 100% cotton, it dries surprisingly quickly—
a dependable fabric that’s thick, absorbent, and quick-drying

While maintaining the gentle feel of 100% cotton, we’ve added moisture-wicking and quick-drying features to make autumn and winter laundry more comfortable. Thicker than a typical T-shirt and less see-through, the fabric gives peace of mind even when worn alone.

It also dries easily indoors and holds its shape well after washing, making it perfect for worry-free daily use.

“Just right” — Perfect for everyday life
A shirt that satisfies both the one who washes and the one who wears it. That “this is it!” feeling that both parents and kids can relate to.

“I want to wear this today!” — a piece kids choose for themselves
Comfortable and easy to move in, this shirt is the one children reach for again and again.

Dries quickly even after washing — reliable even in fall and winter
Despite being 100% cotton, it’s quick-drying and moisture-wicking, reducing laundry stress regardless of the weather.

Thick enough to wear on its own with confidence
Thicker than a standard T-shirt, it’s less transparent and holds its shape well.

Gentle on the skin, tough in wear
Made from 100% cotton that’s kind to kids’ skin — yet strong and long-lasting.
