Neoprene is one of the most widely used materials in water sports gear. It is found in wetsuits, gloves, boots, spray skirts, and a range of kayaking accessories. Understanding what neoprene does and how it works helps you make better decisions about what to wear on the water.
What Is Neoprene?
Neoprene is a synthetic rubber material developed in the 1930s as an alternative to natural rubber. It is made from polychloroprene, a polymer that combines elasticity, durability, and resistance to water, oil, and heat.
The material contains tiny nitrogen gas bubbles that provide insulation and buoyancy. These bubbles reduce heat transfer, which is why neoprene keeps you warm even when submerged in cold water.
Neoprene is available in varying thicknesses, typically from 2mm to 7mm. Thicker neoprene provides more insulation and is better suited to colder water conditions. Thinner neoprene is more flexible and better suited to warmer conditions where freedom of movement matters more than thermal protection.
Is Neoprene Waterproof?
Neoprene is water resistant but not fully waterproof in the traditional sense. The material itself resists water absorption, but wetsuits are designed to allow a small amount of water to enter and be trapped between the suit and the skin. This thin layer of water is warmed by body heat and acts as an additional insulating layer.
For this to work correctly, the wetsuit must fit snugly against the body. A loose-fitting wetsuit allows water to flush through rather than trap, which significantly reduces its insulating effectiveness.
The seams of neoprene garments are typically blind-stitched and glued or taped to minimise water entry at the join points. This construction provides a more water-resistant seal than standard stitching alone.
Is Neoprene Safe To Wear?
Neoprene is considered chemically stable and safe for most people. A small number of people experience skin sensitivity or allergic reactions to the chemical compounds used in neoprene manufacturing. Symptoms typically include skin irritation or rash at the contact points.
If you have sensitive skin and experience irritation after wearing neoprene gear, look for limestone-based neoprene alternatives which use a different manufacturing process and are generally better tolerated by people with chemical sensitivities.
What Is Neoprene Used for in Kayaking?
Neoprene is used across a wide range of kayaking gear.
Wetsuits are the most common neoprene product for kayakers. A 3mm wetsuit provides adequate thermal protection for most recreational paddlers in cool to cold water conditions. A 5mm suit is better suited to cold water kayaking in winter conditions.
Spray skirts use neoprene for the deck and tunnel sections that require a watertight seal around the cockpit rim and the paddler’s waist. Neoprene spray skirts provide better waterproofing than nylon alternatives and are the preferred choice for rough water and whitewater conditions.

Gloves made from thin neoprene of 1.5mm to 3mm protect the hands from cold water and wind without significantly reducing grip on the paddle shaft.
Boots and shoes use neoprene to keep feet warm during launching and landing in cold water. Neoprene boots provide thermal protection while remaining flexible enough for walking on uneven shorelines.

Cockpit covers use neoprene to create a flexible seal around the cockpit opening for storage and transport.
How To Wash and Care for Neoprene
Rinse neoprene gear thoroughly with fresh water after every use, particularly after paddling in saltwater. Salt residue accelerates material degradation and causes seams to break down over time if left untreated.
To wash neoprene, use a small amount of mild soap or a dedicated neoprene cleaner diluted in a bucket of warm water. Gently hand wash the garment and rinse thoroughly. Do not machine wash neoprene gear as the agitation can damage the material and seams.
Hang neoprene gear flat or over a wide hanger to dry out of direct sunlight. UV exposure degrades neoprene over time. Never put neoprene in a tumble dryer or leave it folded while damp as this causes creases that can weaken the material at the fold points.
Store neoprene flat or hanging in a cool, dry location away from direct sunlight and heat sources.
Final Thoughts
Neoprene is the most practical material for cold water kayaking gear. It provides reliable thermal protection, resists water absorption, and remains flexible across a wide range of temperatures. With proper care it lasts for many seasons of regular paddling.
