Leatt Vest MTB ThermaFlow 5.0

Windproof protection for your core with breathable fleece warmth.

The ThermaFlow 5.0 Vest keeps your core warm and protected without overheating—ideal for high-effort rides in cold, dry conditions. Its custom-developed double weave fabric combines a windproof, water-resistant outer shell with a ventilated fleece interior made with lightweight, thermally efficient Graphene yarn. Designed without a laminate, it prioritizes airflow while sealing out wind and light moisture with a PFAS-free dirt- and water-resistant coating and seam-taped construction. It works great on its own or as a midlayer under a shell when the weather turns. With 4-way stretch for freedom of movement, three zippered pockets for essentials, and bluesign® approved fabrics for the planet, the ThermaFlow 5.0 Vest offers focused warmth where you need it most.
