Moomin Sweaters

At SillySanta you'll find festive Moomin sweater styles for women, men and kids, rated 4.9 out of 5 based on over 5 reviews. Match the whole family in Moomin knits for this year's Christmas photo! From the cosy Mummi Oversized Christmas Sweater to the classic Moomin Christmas Sweater, there's a licensed Moomin design for every taste in our collection.

The Mummi oversized knit and the matching Moomin sweater range

The hero of the collection is the Women's Mummi Oversized Christmas Sweater, a relaxed, slouchy knit that's made to be lived in over the holidays. "Mummi" is just the Nordic name Moomin fans use, so you'll see both used here. Alongside it sit the men's and women's Moomin jumpers in a regular fit, which makes coordinating a couples look easy: one of you in the oversized Mummi knit, the other in a regular Moomin jumper, both clearly part of the same family.

Because it's an officially licensed Moomin range exclusive to SillySanta, the prints stay true to the characters rather than the generic festive knits you see everywhere. If you want the wider world beyond sweaters, the pyjamas, hoodies, socks and slippers all live on the main Moomin hub.

Choosing your fit and size in a Moomin sweater

There are two fits to know. The Mummi is deliberately oversized and relaxed, so it sits loose and layers happily over a shirt or long-sleeve tee. The men's and women's Moomin jumpers are a regular fit, so pick the size you'd normally wear. If you're between sizes on either style, size up. For reference, our models are around 175 to 187 cm and wearing a S to M, which gives you a sense of how the regular fit falls.

Material and care

Materials vary across the styles, so there isn't one single fabric for the whole collection. Some are 100% acrylic, while others are 98% recycled polyester with 2% elastane, with one style made of 98% recycled materials. All of them are knitted with high-quality yarn and come out super soft and comfy. Keep them looking good with a gentle machine wash at a maximum of 30°, washed with similar colours, then dry flat. No tumble drying, no bleach and no dry cleaning.

Styling it for the occasion

This is knitwear built for the season's calendar. The oversized Mummi knit is the easy win for relaxed family dinners and lazy Christmas mornings, worn with jeans or leggings. The regular-fit Moomin jumpers tidy up a little more for a Christmas party or the office, and they're the obvious pick when your workplace runs a Christmas sweater day. Whichever you choose, it's a soft, characterful layer that does the festive job without trying too hard.
