Proudly, unapologetically, head-to-toe Canadian.

The Canadiana Adult Onesie is a love letter to everything that makes this country worth celebrating — the wide open landscapes, the iconic wildlife, the kind of quiet pride that doesn't need to be loud to be felt. Wrapped in a print that captures the spirit of Canada from coast to coast, this onesie is made for the slow, golden moments that feel most like home — a fireside evening, a cabin morning, a holiday gathering where everyone's in matching PJs and nobody's complaining about it.

Crafted from 100% GOTS certified organic cotton that's soft, breathable and made for real family life, this onesie features rustic wooden buttons and a functioning butt flap that brings just the right amount of cheeky Canadian charm. Snug ribbed cuffs keep everything warm and in place, and the gentle stretch means you can move freely through every easy, unhurried moment the day brings.

Because some onesies are just pajamas. This one is a statement. 🍁

Made from 100% GOTS certified organic cotton. Designed in Vancouver, BC — with love from our family to yours.

Made with Heart

Every print starts with a spark — a sketch inspired by the woods, the laughter echoing through the cabin, the smell of pine and pancakes. We don’t chase trends; we design stories you can wear. Each pattern is created in-house by our family, for real families.

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.

Comfort You Can Feel Good About

We use GOTS certified organic cotton and thoughtful fabrics because comfort should feel good in every sense. Soft on skin, gentle on the planet, and safe for the little dreamers who live in these PJs.
