The Leatt ThermaFlow 2.0 MTB Jacket gives warmth and adaptability for a wide range of riding conditions. Constructed with bio-based WarmYarn technology, this advanced technical fleece provides exceptional thermal efficiency, natural odour resistance, and rapid moisture management, ensuring comfort whether worn as a standalone layer in mild weather or as a midlayer during cold winter rides.

Its stretchy, low-profile design allows unrestricted movement, conforming naturally to the rider’s posture, while the under-helmet hood and elasticated cuffs create a snug, wind-blocking seal for added protection against the elements. Zippered side pockets offer secure, accessible storage for small essentials, and a PFAS-free water-repellent coating enhances durability while maintaining eco-friendly performance.

Designed for riders who value technical warmth, mobility, and sustainability, the ThermaFlow 2.0 Jacket is the ideal companion for consistent comfort across variable trail conditions.
