Does the Manta Sleep Mask Pro get too hot? What materials were used in the mask?

The Manta Sleep Mask Pro uses advanced materials and ventilation for unmatched breathability. It features specialized ventilation holes and perforated materials that gently guide heat away from your face — so you stay cool and comfortable as you sleep.

The outer part of the strap is made of incredibly lightweight and breathable polyester mesh. The eye cups and interior of the mask are made of Tactel® – an advanced fabric that’s 2x as soft, 3x as durable and 8x faster drying than most fabrics.
