Helmet Inner Helmet Inner Cap [Set of 4 & Craftsman Supervised] Sweat Absorbing

【Set of 4 - Heatstroke Prevention Goods - Don't Let This Summer's Heat Get You Down】These helmet liners are supervised by craftsmen and developed to suit Japan's climate, making them an essential item for summer. Japan's summers are hot and humid, and for those who wear helmets for long periods, especially in construction, logistics, and factory work, sweat and stuffiness can be a major source of stress. These helmet liners suppress stickiness caused by sweat, effectively prevent temperature rise in the head, and are ideal heatstroke prevention goods.
【Breathable Mesh - Excellent Ventilation】The helmet liner caps feature a double mesh structure that is resistant to stuffiness and offers excellent breathability. The three-dimensional mesh design of the sweat-absorbing liner creates space for air to circulate freely, efficiently releasing heat and moisture from the head. This keeps the head at a comfortable temperature for extended periods, eliminates stuffiness inside the helmet, maintains coolness even during work under the blazing sun, and reduces the risk of heatstroke.
【Highly Absorbent - Sweat Wicking - Quick Drying】The inner caps have high water absorbency and a fast drying rate. The main body uses polyester, which has good quick-drying properties, as the surface material, and a highly absorbent cotton material is used for the lower layer. This combines the sweat-absorbing properties of cotton with the quick-drying properties of polyester, allowing sweat to be quickly absorbed → diffused → evaporated. This eliminates worries about sweat getting into your eyes and keeps your head from staying damp for long periods, ensuring comfort at all times.
【Easy to Attach - Secure Fit】Attaching and detaching takes just two steps, with no complicated procedures. Step 1: Hook the liner onto the plate inside the helmet. Step 2: Push the liner in firmly, spread it out, and adjust the shape. The liner does not affect the helmet's size adjustment and can be worn without discomfort, minimizing stress during work.
