AAAH! Brain freeze! There’s a fair bit to remember when you’re swimming in cold water – breathing through your gasp reflex for one – and it’s all a lot easier if your brain is working properly.

The Outdoor Swimming Cap uses high-grade 3mm neoprene to keep your head warm when the water temperatures reach "will I go blue after this one?" levels. With three different sizes and a velcro chin strap, the Outdoor Swimming Cap is designed to provide a secure fit, reducing flushing and retaining as much body heat as possible in chilly waters.

The outside of the neoprene swimming cap is coated with GlideSkin, a shiny, more streamlined type of neoprene – a bit like the top of a dolphin’s head. Its main porpoise is to reduce drag in the water, allowing you to slice through lakes, rivers and waves with ease. GlideSkin also repels water and dirt and retains heat more efficiently than standard neoprene.
