Choosing The Right Fit
Zerofit baselayers are designed as technical performance layers for riding, training and outdoor use. The fabrics are high-stretch and designed to sit close to the body, helping them work properly under motorcycle gear.
If you prefer a more relaxed fit, or you are between sizes, we would generally recommend choosing the larger size.
This guide brings together the main Zerofit sizing information for IceSkin baselayers, Heatrub Ultimate baselayers and Heatrub Ultimate leggings.

IceSkin Baselayers
The Zerofit IceSkin range is designed for warm-weather riding, using a lightweight, high-stretch technical fabric that moves comfortably with the body while helping manage heat and moisture under motorcycle gear.
The fit is more performance-focused and slightly closer fitting than a standard t-shirt or casual baselayer. The IceSkin range is unisex.

Need Help Choosing Your Zerofit Size?
If you’re unsure about sizing, feel free to get in touch or visit us in-store. We’re happy to help recommend the right fit based on your normal riding gear, layering preferences and how you prefer your baselayers to feel under a jacket, trousers or suit.
The Zerofit IceSkin Short Sleeve Baselayer is built for hot-weather riding, when staying cool and dry makes all the difference. Designed for temperatures up to 40°C, it combines Zerofit’s Cool Stamp Tech® and Rhombus Mesh Design to help manage heat, sweat and comfort on the bike.
Cool Stamp Tech® sits across the front of the baselayer and is designed to create a cooling sensation when it absorbs moisture from the skin. On the back, the Rhombus Mesh Design targets the area where heat and perspiration tend to build up most, helping moisture move away more efficiently when the ride heats up.
The lightweight stretch fabric moves easily with you without feeling restrictive under riding gear, whether you are commuting, touring or riding off-road in hotter conditions. The silky-smooth finish also helps reduce that sticky feeling riders often get under jackets or leathers during summer riding.
Developed in partnership with Glenn Irwin and worn by riders across Bennetts BSB, WorldSBK and the Isle of Man TT paddock, the IceSkin is Zerofit’s most advanced cooling baselayer for serious riding in the heat.
Prefer more arm coverage for touring, changing temperatures or additional sun protection? Also available in the long sleeve version.
