Classic. Cozy. And yes — there's a trapdoor. The Buffalo Plaid Adult Onesie is the one that starts conversations, ends arguments about what to wear on Christmas morning, and makes the family photo absolutely unforgettable. That iconic red-and-black Canadian check, head to toe, in a full-body onesie with our signature Moose Caboose trapdoor detail. It's cheeky in the best possible way. Wear it camping, wear it on Christmas Eve, wear it any slow winter morning where the vibe calls for something both cosy and completely ridiculous — in the very best sense. Crafted from 100% GOTS certified organic cotton jersey that's soft, breathable and built for real family life, this onesie fits like a dream from the very first wear. Snug ribbed cuffs keep everything cosy and secure, the full-body fit gives you all the warmth of a proper onesie, and the gentle stretch means you can move freely through every festive moment — from Christmas morning cocoa to the fireside laugh you didn't see coming. Part of the Buffalo Plaid family matching collection. Because some traditions are worth starting — and the Moose Caboose is always worth the photo. 🪵 Made from 100% GOTS certified organic cotton. Designed in Vancouver, BC — with love from our family to yours. Sizes: XS · S · M · L · XL · 2XL
