Just by placing it inside hats or helmets, it cuts out solar radiation heat! It protects your head from heat. *Currently, a cool towel (280x460) is a gift!
There are three types of heat transfer: "convective heat," "conductive heat," and "radiant heat," with "radiant heat" being the most dominant in terms of human body temperature perception. Cutting down on radiant heat is very effective for heat prevention measures. ■ Features of the moisture-permeable waterproof heat-shielding sheet "Heat Boushi" - Heat Boushi is a high-reflection heat-shielding sheet that maintains moisture-permeable waterproof performance. - One sheet of Heat Boushi enables waterproofing, ventilation, and heat shielding. - The ventilation inside hats and helmets is maintained, ensuring comfort. - Easy to install and ready for immediate use. ■ Specifications Size: Thickness 0.4mm x Length 240mm x Width 240mm Shape: Four-leaf shape Material: Aluminum, moisture-permeable prevention sheet ★ For a limited time, receive a cool towel (280mm x 460mm) as a gift ★ By wetting it and placing it on your head, you can add a refreshing sensation!!
