Bamboo bedding for warm sleepers
Short answer: If you sleep warm, the sheet matters more than the duvet. You lie on the sheet all night, and that is where the moisture has to go first.
The sheet first
The moisture from your back goes into the sheet. If the sheet cannot pass it on, it turns clammy however good the duvet is. See bamboo bedding.
Percale rather than sateen
Percale feels cooler, because the surface has less contact area with the skin. For warm sleepers it is almost always the right choice.
The weight of the duvet
A light duvet with a natural filling or a thin synthetic filling is better than a heavy one. Weight is insulation, and insulation is what you want to avoid.
The nightwear must not seal
If the nightwear is dense synthetic, the moisture never reaches the sheet. See bamboo nightwear for men.
Wash without fabric softener
Fabric softener cancels the moisture transport in every layer at once. See washing and care.
