A Fire Stone glows inside every Women’s Flareon Onesie

Hold a Fire Stone close to an Eevee and the room changes temperature. Fur turns the colour of embers, a flame sac starts to burn inside, and the gentlest of creatures becomes a living campfire. This Flareon onesie for adults radiates the same heat in vivid orange fleece, with golden yellow cuffs and a fluffy yellow tail. Tall pointed ears crown the hood, ready to twitch at the first crackle of a log. Inside, the temperature is said to climb past anything a thermometer can read. Outside, it just looks impossibly fluffy.

Men’s Flareon Onesie for evenings spent close to the flames

The adult Flareon onesie makes winter feel optional. These onesie pyjamas trap warmth like a hearth, the buttons fasten without a fuss, and elasticated cuffs keep the heat from escaping during a snowy walk to the postbox. Log cabin weekends, Bonfire Night parties and long gaming sessions all burn brighter in orange. The yellow tail trails behind like a plume of flame, and the ears stand tall enough to cast a shadow on the wall. Hot chocolate is welcome, but hardly necessary. Light the spark before the first frost, and keep the cosiest fire type curled up at home.

The original trio

The Jolteon onesie crackles alongside in electric yellow for a stone evolution duo. The full family tree grows in the Pokémon onesies collection. Other favourites warm up among the adult onesies.

Frequently Asked Questions

They’re made to keep you warm on the sofa through autumn and winter, so yes, they’re cosy. The relaxed fit lets air move around, though, so you won’t get that stuffy feeling you get from tight pyjamas.
Machine wash at 30°C on a gentle cycle. Turn them inside out and pop them in a mesh laundry bag to protect the hood. Skip the tumble dryer and the iron. They air-dry quickly and fluff right back up on their own.
Yes, every onesie we sell is unisex. The roomy cut works for men and women alike, our kids’ styles fit girls and boys just the same, and our baby sizes are cut the same way for everyone. Just check the size chart to find your fit.
