The Revolution Thermal Shirt is perfect for mid-season and winter thanks to its 3D structure made with DRYARN® and MERYL® hypoallergenic and bacteriostatic microfibre. DRYARN® is high performance, more breathable than polyester, more insulating than wool and lighter, and has multiple compression zones that improve muscle performance. Equipped with 3D areas, the shirt also offers exceptional thermoregulation and breathability, for unique comfort.
