The Breathable MTB Thermal Vest ThermaFlow 5.0 is designed for those who ride hard even when temperatures drop, without sacrificing comfort and freedom of movement. Perfect for winter rides or colder mid-seasons, it keeps the torso warm and protected without overheating, so you can focus solely on the trail line. The specially developed double-weave fabric combines a fully windproof and water-resistant outer layer with a ventilated fleece inner made of GRAPHENE yarn: lightweight, durable, with superior thermal properties. No stiff laminates: the ThermaFlow 5.0 favors airflow and breathability while providing protection from wind and light moisture thanks to DWR C0 water-repellent treatment without PFAS and taped seams. The regular fit, adjustable hem, and 4-way stretch follow every movement on the saddle, while the three YKK zippered pockets keep smartphone, keys, and small items safe. Bluesign® approved fabrics and plastic-free packaging complete a technical garment that combines performance, comfort, and environmental care: ideal to use alone on cold and dry days or as a mid-layer under a shell when weather worsens.
