Some places stay with you. This one you can wear.

The Cabin In The Woods Adult Onesie is for the person who feels most like themselves somewhere deep in the trees — where the pace is slow, the coffee is hot and there's nowhere else to be. The beloved watercolour forest print wraps the whole onesie in that dreamy, nostalgic cabin feeling, and the surprise Buffalo Plaid back flap is the kind of detail that makes people gasp and then immediately laugh — in the very best way.

Because yes, there's a trapdoor. And yes, it has Buffalo Plaid on it. You're welcome.

Crafted from a 95% GOTS certified organic cotton and 5% elastane jersey knit that's soft, breathable and moves with you through every easy, unhurried moment, this onesie is made for the long, cosy hours of a proper day off. Snug ribbed cuffs keep everything warm and in place, the functional back flap closes with snaps for when you need it and opens when you don't, and the gentle stretch means you can curl up, stretch out and do absolutely nothing with great comfort all day long.

Part of the Cabin In The Woods family matching collection — because the whole family in matching onesies by the fire is a memory worth making. 🌲

Made from 95% GOTS certified organic cotton, 5% elastane. Designed in Vancouver, BC — with love from our family to yours.
