Description
The LEATT Jacket Thermaflow 2.0 is Leatt's solution for riding in cold weather while maintaining optimal thermal regulation. Its construction relies on a subtle balance: a windproof and insulated front panel to protect vital organs from the cold, combined with highly breathable panels on high-perspiration zones.
Unlike traditional winter jackets that are often too heavy, the Thermaflow is designed for intense effort. It uses a lightweight quilted structure that retains heat where needed, while allowing moisture to escape quickly. For 2026, this version has been refined to offer a more ergonomic fit, allowing total freedom of movement on the bike.
What temperature range is it designed for? It is ideal for temperatures between 0°C and 10°C. With a suitable technical base layer, it allows comfortable riding even in light frost.
Is it fully waterproof? No, it is a thermal and windproof jacket. It resists a light shower thanks to its DWR treatment, but for riding in continuous heavy rain, a jacket from the HydraDri range remains necessary.
