Leatt Jacket MTB ThermaFlow 2.0

Technical fleece warmth—on its own or under a shell.

The ThermaFlow 2.0 Jacket is a versatile technical fleece built for warmth on cool rides—or as a breathable midlayer when the temps really drop. Made from bio-based WarmYarn with a soft brushed interior, it delivers thermal comfort, quick-drying performance, and natural odor control in a stretchy, low-profile fit. The under-helmet hood, PFAS-free DWR coating, and snug cuffs help seal out the chill, while zippered side pockets secure essentials. Made with bluesign® approved fabrics, this go-to layer is a smart addition to any cold-weather riding kit.
