Thermal Cabin In The Woods Infant Sleepsack
Please note: This item is not pre-shrunk. Because it’s made from natural materials, you can expect about 15% shrinkage if dried on high heat. We recommend sizing up, washing in cold and air-drying to maintain the perfect fit. The fabric softens beautifully over time, making these pajamas even cozier with every wear.

Rooted in Family Tradition
Millie + Moose began in a Canadian family workshop — where bedtime stories met fabric and tradition met design. What started as small-batch pajamas for gift shops has grown into something we never expected: a brand that connects thousands of families across Canada through matching moments.
