Reusable Helmet Cooling Insert with Pressure Design

This round headwear accessory is designed as a helmet cooling pad and helmet liner insert for use inside a hat or helmet. With a 25 cm diameter and a lightweight 100 g build, it offers a compact fit that is easy to place where cooling support is needed. Built with a soft TPU surface and phase-change cooling material, the cooling liner is meant to provide a cooler, smoother wearing experience. Its segmented, flower-like layout gives it a distinctive structure that helps it fit neatly inside headwear without feeling bulky. As a reusable hat cooling pad, it can be cooled again and used repeatedly, making it well suited to daily routines, commutes, or long periods of wear. The pressure design adds comfort by reducing the heavy feeling that headgear can sometimes create, while still staying lightweight and easy to handle.
