I used to suffer from night sweats but now since I wear the NATTCOOL sleep tech set. I no longer have that problem.

The pajamas really do work to help you stay cool while you're sleeping at night. The moisture absorbing tech helps you stay dry if you do get a little sweaty and they dry really fast. Super comfortable to wear. Definitely worth the price!
