I bought 2x "Bamboo Night Caps - Leslie", 1x lilac & 1x baby blue, to match my pyjama colours & dressing gown. I have a coloumn heater in my bedroom at night in winter, so I use these caps in winter, now that I have no hair from chemo. They are so comfortable. I know that my head will be warm on these cold winter nights in bed at home (I wear thicker night caps in hospital). The double bamboo layers are warm, but I have to remind myself that these bamboo caps (because they're double-layered), require extra drying time & repeatedly turning inside-out until dried. These bamboo night caps give my peace of mind as I sleep, and my favourite is the lilac colour.
