Product description
The hooded monster pyjamas that make any evening one to remember.
Thick, wonderfully soft flannel, a monster hood with horns and little ears, and a relaxed cut made for lounging, sprawling and hibernating. You put it on to make people laugh, and you keep it on because you've never been this comfortable.
WHY YOU'LL LOVE IT
- Pure softness: plush fleece flannel that keeps you warm yet stays breathable, never stuffy.
- A proper monster hood: horns, ears and big embroidered eyes. A guaranteed reaction, whether on Christmas Eve or at breakfast.
- Nine colours: Green, Blue, Red, Black, White, Yellow, Purple, Beige or Pink, to match (or not) with your other half.
- Machine washable: 30 °C on a delicate cycle, then air dry, and it comes out as good as new.
THE GIFT THAT LANDS
This is the present people remember: birthdays, Christmas, Secret Santa, or simply to shake up the routine. Wild on the outside, cosy on the inside.

Ideas and occasions
- A gift people remember: Christmas, birthdays, Secret Santa or just because: it gets a laugh when it's unwrapped, then gets worn all winter long.
- Cosy nights in: Box-set evenings, lazy Sundays, working from home with the camera off: it's genuine loungewear, not a one-night costume.
- Matching pairs and groups: Two different colours for a couple, or a whole pack of monsters for a hen do, stag do or pyjama party.
Frequently asked questions
Which size should I choose?
Go by your height in centimetres: S under 150 cm, M for 150–160 cm, L for 160–165 cm, XL for 165–170 cm, XXL for 170–180 cm and above. If you're between sizes, choose the larger one, as the cut is deliberately roomy.
Is it suitable for both women and men?
Yes, the fit is unisex and roomy through the shoulders, waist and hips. Only your height matters when choosing a size.
What is it made of?
100% polyester fleece flannel, thick and very soft to the touch. It keeps you warm while staying breathable.
How do I wash it?
Machine wash at 30 °C on a delicate cycle, ideally inside out, then air dry. Avoid the tumble dryer, which would spoil the softness of the flannel, and don't iron the embroidery.
Is it a costume or proper pyjamas?
Both: the horned, big-eyed hood is a hit at parties, but the thick flannel and relaxed cut make it first and foremost loungewear you'll keep wearing long after the party.
How much is delivery and how long does it take?
