Flapjack Adult Onesies

Our funny adult onesies are one of our “beary” best-sellers! Designed with 100% combed cotton, these matching pajamas—we call them Flapjacks—are super soft and warm. We offer these adult options in a variety of fun Christmas styles and other patterns that’ll keep you oh so comfortable and cozy!

When we decided to take on an Adult onesie design, we used the traditional long john fit as our inspiration. Our onesie pajamas fit snug against your skin yet are roomy enough to be a great choice if you are looking for maternity lounge wear! Like long johns, the Flapjacks feature a ribbed cotton make with a “cheeky” buttoned flap on the back. Yes, this flap really opens up! These super stylish Flapjacks are offered in unisex sizing, so please be sure to check our handy size guide before placing your order!

Our funny onesies for adults features an assortment of fun and stylish options! There are several holiday patterns to choose from, including the best-selling No Peeking Flapjack. This onesie features a cream and green color scheme, with adorable trees all throughout the cotton fabric. Look closely and you’ll spot our peeking reindeer from between some of those trees. Our Bear Essentials Flapjack takes on the Fair Isle pattern—a technique of alternating colors and patterns—with vibrant bears and trees. Its woodsman appeal is perfect for Dad and outdoors lovers! The Sweet Cheeks adult onesies feature delightful gingerbread men, peppermints, and gumdrops for tasty looking PJs! Get some fa-la-la-la-la into your holiday portraits, parties, and Christmas morning with these Flapjacks!

Our very popular bear and moose patterns each feature good humor prints and great colors. The “beary” popular red and black Bear Cheek plaid Flapjack features the behinds of two bears on the flap with “Bear Cheeks” written in a fun typeface across the flap. Everyone knows we also have a soft spot for moose, so naturally they’re a part of our onesie pajamas collection! The grey and red Moose Caboose Flapjacks gives a little style to the tush with a plaid trapdoor! Are the kids and Dad a little on the grumpy side in the morning? The Classic Moose Flapjacks in blue read “Don’t Moose with Me!” on the flap to commemorate those before breakfast grumps! Our men’s and women's onesie pajamas are wonderful around the Christmas holidays and year round. If you have questions about our irresistible adult onesies, please feel free to contact us!
