Men's Pyjamas

At SillySanta you'll find over 90 styles of mens pyjamas, also known as men's PJs, from soft flannel sets and licensed character prints to bold novelty onesies. It's the men's slice of our matching-family range, so a guy can line up with the rest of the household for the Christmas-morning photo. Pick the matching set everyone's wearing, or go your own way with a onesie no one else dares to.

The mens pyjamas range, built for the whole-family Christmas photo

The men's range sits inside our wider pyjamas collection, which is where the matching-family idea comes together: women's, kids' and men's styles in the same prints so the household can coordinate without trying too hard. On this page you get the men's-fit versions, cut a little roomier and longer in the leg so a taller frame isn't left with cropped ankles. With 92 products spanning flannel two-pieces, Christmas pattern and knit prints, licensed character sets and fleece onesies, there's a style here whether the brief is "classic and comfy" or "loudest one in the room."

Most of the two-piece sets are a soft 95% cotton, 5% elastane blend, so there's a touch of give without losing that proper cotton feel. A few are 100% cotton, and some are made from 100% recycled polyester if you'd rather lean greener. None of it is the stiff, scratchy stuff you grow out of by Boxing Day.

Flannel sets: the relaxed classic

The flannel two-pieces are the safe bet in the men's pyjamas line-up. The Men's Red Flannel Christmas Pyjamas and Men's Blue Flannel Christmas Pyjamas are brushed soft, warm enough for a cold morning by the tree, and still breathable cotton so you're not overheating an hour later. It's the relaxed long-sleeve-and-trousers look most men reach for first: roomy through the body, easy to throw on, and the kind of thing that survives years of lazy Sundays, not just December.

Christmas pattern and knit prints

If you want festive without going full novelty, the pattern and knit sets are the middle ground. There's the Men's Red Christmas Pattern Christmas Pyjamas and its blue twin, the Men's Red and Green Christmas Knit Christmas Pyjamas with that cosy fair-isle look, plus the cheerful Men's Red and Green Hohoho Christmas Pyjamas and the Men's Gingerbread Christmas Pyjamas. They read as proper grown-up pyjamas with just enough Christmas in them to fit the theme.

Character and licensed prints

This is where a guy can match the rest of the family on the print, not just the colour. The men's range carries genuinely licensed designs you won't find cobbled together elsewhere: Moomin sets like the Men's Snufkin and Men's Moomintroll pyjamas, the atmospheric Men's Christmas Scenery Christmas Pyjamas, a Warner Bros. Men's Blue Harry Potter set, and The Grinch for anyone who does Christmas with a raised eyebrow. The Moomin and Warner Bros. styles are exclusive to SillySanta, so if dad and the kids both want Snufkin or Grinch, you can actually pull that off here. We've kept these to the men's-fit versions; the full character line-ups live across the other family collections.

Novelty onesies for men

For the men who treat Christmas as a sport, the onesies are the throw-it-on-and-go option. They're a soft, cosy fleece, and the product note isn't wrong that you can "get dressed for a Christmas party in just 10 seconds." Step into it, zip up, done. The line-up runs from festive picks like the Men's Reindeer Onesie, Men's Candy Cane Onesie and Men's The Grinch Onesie to all-year characters: Monster, Unicorn, and the genuinely huggable Men's Brown and Grey Teddy Bear Onesie. They're the loud, fun end of the men's pyjamas range, equally at home at a party or collapsed on the sofa.

Fit, sizing and length

Most of the men's pyjamas come in a Regular fit, with some styles also offered in Slim, so you can pick how relaxed you want them. The standard advice is the simplest: choose the size you'd normally wear, and if you're between two sizes, size up rather than risk it being snug. For length, the models in the photos stand roughly 177 to 189 cm tall wearing sizes S to L, so you can eyeball how the trousers and sleeves are likely to fall on a taller frame before you order. The onesies are forgiving by design, so the same "size up if in doubt" rule keeps them comfy to lounge in.

Finish it with a matching sleep mask

If you're committing to the look, the matching accessories tie it together. We stock sleep masks in the same red and blue Christmas patterns as the pyjama sets, so the coordination carries right through to lights-out. They're a small, easy add-on, and they make a tidy little extra in a gift bundle.

Why these mens pyjamas work as a gift

Pyjamas are one of the few presents a man will actually use on repeat, and these make the buying decision easy. Sizing is forgiving, so you don't need his exact measurements: pick what he'd normally wear and size up if you're unsure. You can match him to the rest of the family for the Christmas card, or hand over a onesie that's unmistakably his. With more than 200,000 Christmas pyjamas sold, it's a present that lands reliably, soft, warm, and worn long after the wrapping paper's gone.
