The stay dry organic cotton insert is just too promising. I have been using it since January 2020, and found this insert to be working wonders even during winters. I had been using it along wih hemp ,where I only removed the hemp to be dry in the morning, which therefore proves that the insert alone was good enough for a whole night. At present, being summers,I use only the insert alone without additional boosters and I'm very happy with the performance . Another classy product from the house of bumpadum. Thank you
