If you're searching for pajama sets that are genuinely soft and breathable (not just marketed that way), it comes down to two fabrics: bamboo viscose and cotton-modal. Both are worth knowing the difference between.
Bamboo viscose is the softer, more temperature-adaptive of the two. It has a naturally wicking fibre structure that pulls moisture away from skin, and it adjusts to keep you warm when it's cool and cool when it's warm. Our Georgia Rylan Bamboo collection is built entirely around this fabric, sized XS through 3XL.
Cotton-modal is a close second — a blend that's more absorbent than plain cotton, with a "cool-to-the-touch" feel and excellent stretch. It's the fabric behind most of our PJ Salvage collection, including the popular Whimsy sets.
How to choose between them: if you're managing hot flashes or night sweats specifically, bamboo tends to be the stronger performer. If you want something breathable with a bit more structure and print variety, cotton-modal is a great everyday option. Either way, skip anything 100% polyester if breathability is your priority — it traps heat rather than releasing it.
The physical need for genuinely breathable, temperature-regulating fabric isn't just a preference — hot flashes and night sweats affect the large majority of people going through menopause, according to Chatelaine's reporting on research from The Menopause Society, which is a big part of why we've built so much of our collection around fabric performance, not just print.
