NRS HydroSkin 0.5 Helmet Liner: Lightweight neoprene helmet liner

HydroSkin 0.5: Thermal Comfort Under a Canoeing Helmet

NRS HydroSkin 0.5 Helmet Liner It is a lightweight neoprene beanie designed to be worn under a kayaking, rafting, or rescue helmet. It provides an extra layer of insulation in cold weather without significantly increasing the bulk under the helmet or restricting movement.

It is suitable for situations where wind, cold water, and moisture quickly reduce thermal comfort around the head. The open design around the ears helps maintain situational awareness and the ability to hear instructions while paddling, rafting, or participating in rescue operations.

0.5 mm HydroSkin® and PowerSpan™ neoprene

The hat is made of 0.5 mm HydroSkin® neoprene with a flexible outer fabric made of PowerSpan™ nylon and spandex. The four-way stretch helps the cap conform to the shape of the head, fit comfortably, and avoid causing pressure under a helmet.

• 0.5 mm HydroSkin® neoprene: Lightweight thermal insulation without excess bulk.
• PowerSpan™: Four-way stretch nylon-spandex fabric for a comfortable fit.
• Tight-fitting profile: Suitable for use under a kayaking or rafting helmet.
• Lightweight construction: It doesn't feel heavy even when you're out on the water all day.

ThermalPlush™ and a reflective titanium layer

The inner layer is made of a soft, water-repellent material ThermalPlush™, which feels pleasant against the skin and helps improve thermal comfort. The reflective titanium-laminate layer reflects some of the body's heat back toward the head, contributing to better insulation in cold conditions.

• ThermalPlush™: A soft, water-repellent inner layer for comfort and to reduce the feeling of cold.
• Titanium laminate: It helps retain body heat and enhances the insulating effect.
• Lightweight thermal protection: Suitable for cold mornings, as well as spring and fall conditions.

DWR treatment to protect against the cold caused by evaporation

The outer surface is coated with DWR treatment, which repels water and helps minimize the cooling effect caused by moisture evaporation. You'll especially appreciate this in windy conditions, when exposed to splashing water, and when repeatedly getting wet while paddling or rafting.

• DWR water-repellent finish: It helps reduce the absorbency of the surface material.
• Less cooling due to evaporation: Greater comfort in windy and wet conditions.
• Practical use: Suitable for activities involving frequent contact with water.

Flat seams and loose tabs for orientation

Flat-lock seams help reduce pressure points and friction under the helmet. The cap does not cover the ears, so it does not block out ambient sounds—an important safety feature when communicating with the crew, an instructor, or a rescue team.

• Flat-lock seams: A flat seam for comfort without unnecessary friction.
• Loose Ears: Improved audibility of instructions and orientation in the surroundings.
• Helmet compatibility: A slim design that fits under most kayaking helmets.

Expert Advice

Choose a cap based on your head circumference, and always try it on with the helmet you use. The HydroSkin 0.5 Helmet Liner should fit snugly but must not create pressure points under the helmet. Exposed ears are an advantage for communication and safety, but in very cold water, consider adding a neoprene hood to cover your ears. After use, rinse the cap with fresh water and dry it in the shade.
