Crazy Viper shirt 2025

The Viper T-shirt is designed for technical trekking, with a lightweight fabric and a clean, essential look. It is designed with differentiated fabrics that optimise protection and breathability in every area of the body, thus giving it a superior level of protection and functionality: the entire torso and sleeves are in Performesh fabric, which is breathable, quick-drying, odour- and UV-resistant, while the underside of the waistband is in an even lighter and more breathable mesh. Its technical nature is underlined by the shoulder straps reinforced with a soft, yet durable carbon thread fabric to protect against backpack wear.
