Bamboo Jammers—pajamas for more than just the bedroom.

Bamboo Jammers is the name we give to our core women's PJ set range — it's where we put the styles that define what This Is J is about. Every set is made from our signature bamboo fabric: moisture-wicking to keep you comfortable through the night, temperature-regulating so it works across the seasons, and soft in a way that cotton genuinely can't match. We've been making bamboo sleepwear since 2004 and this is the collection that most of our customers come back to.
The range covers a wide spread of styles — tank sets, short sleeve sets, long sleeve sets, button-down PJ sets, harem sets, henley sets, and oversized tee options — all available in a rotating range of prints and solids. Sizes run from XS to XXL, and our product photography is all shot on real models with their measurements listed, so you can make an informed decision about fit rather than guessing from a flat lay. Most styles are also available as separates if you want to mix and match across prints.
If you're buying your first set of bamboo pajamas, this is where we'd point you. The Bamboo Jammers range is our most-stocked collection, which means it has the widest choice of styles and the most consistent availability across sizes. New prints come through regularly, and popular colourways sell out quickly. Our Comfort Club loyalty programme rewards repeat purchases, and members get first access to new arrivals and sale events — worth signing up for if you plan to come back.
