Leatt MTB Thermaflow 5.0 vest 2026

The ThermaFlow 5.0 vest keeps your torso warm and protected without overheating, ideal for high-intensity rides in cold, dry conditions.

Its custom-developed dual-weave fabric combines a windproof, water-resistant outer shell with a ventilated fleece interior made from lightweight, thermally efficient GRAPHENE yarn. Designed without a laminate, it prioritizes airflow while protecting against wind and light moisture thanks to a PFAS-free, dirt- and water-resistant coating and taped seam construction. It works great on its own or as a midlayer under a shell when the weather changes. With 4-way stretch for greater freedom of movement, three zippered pockets for essentials, and bluesign®-approved fabrics for environmental responsibility, the ThermaFlow 5.0 Vest delivers targeted warmth where you need it most.
