  A 2-pack of warm, long-sleeve underwears made from soft jersey fabric that feels so comfortable, kids will want to wear them all day.

  Ultra-soft, fluffy 100% cotton jersey

  Babies’ skin is very sensitive and prone to sweating. That’s why baby underwear is typically made from nearly 100% cotton, but even 100% cotton fabrics can feel very different depending on how they’re knitted. This double-layer jersey fabric is breathable and helps prevent moisture from building up, while providing just the right amount of warmth. Soft, fluffy, and cozy, it’s an ideal fabric for keeping little ones warm and comfortable during the cooler fall and winter months.

  Outer seams at the sides help reduce bulk and irritation

• 

  Excellent stretch and breathability

  Warm and cozy, yet surprisingly lightweight. The soft jersey fabric offers excellent stretch, while cotton’s natural breathability and moisture absorption help prevent stuffiness, even when kids are active. Enjoy a plush, soft feel that gently wraps them in comfort.

  Perfect for daycare! Comes with a name label

  At daycare and preschool, it's standard to label all belongings—including clothing—as part of the entrance preparation, according to enrollment guidelines. PUPPAPUPO’s name label makes labeling easy: it’s designed to resist smudging even when written on with a permanent marker. Plus, the label offers two writable sections, so when passing clothes down, simply cut off the used portion—no need for iron-on name labels.

• 

  The tag is placed on the outside so it won’t touch the skin

  No more scratchy care labels or tags against delicate skin. They’re placed on the outside for comfort, with thoughtful details designed especially for kids.
