About this collection
Base Layers
Base layers do the invisible work: wicking sweat in summer, holding warmth in winter, and letting leathers slide on and off like they should. Functional underwear from Dainese, Spidi, Knox, RST and IXON — tops, bottoms and one-piece unders for every season.
Match the fabric to the calendar: mesh and quick-dry weaves for hot trackdays, brushed thermal builds for winter touring. A close fit is the point — a base layer that wrinkles under leathers defeats itself. Most ranges run true to size with stretch panels doing the fine adjustment.
