Zerofit Iceskin Long Sleeve Motorcycle Base Layer Top - Black The Zerofit Iceskin long sleeve motorcycle base layer top has been developed in partnership with Glenn Irwin, the most successful superbike rider in the history of the prestigious North West 200 road race. The unisex IceSkin motorcycle base layer top fuses two key technologies, Cool Stamp Tech® and Rhombus Mesh Design, which keep riders cool and sweat free.

The thin, lightweight fabric features optimal stretch capacities, allowing riders to move freely without stress and the long-sleeve version also allows riders to slip on their suits or jackets with ease.
