DESCRIPTION
The Viper is a technical trekking t-shirt from CRAZY built on a simple yet effective principle: using different fabrics in body areas where maximum breathability is needed and where greater sun protection is required. The result is a garment that dynamically adapts to activity, without compromising between lightness and functionality.
Construction and Materials
The torso and sleeves are made of Performesh, a fine mesh technical fabric that promotes continuous ventilation and quickly wicks away moisture during prolonged uphill efforts. The shoulders and areas subject to greater UV exposure or contact with harnesses and backpacks are made of a more compact fabric, designed to offer protection and abrasion resistance where the shirt needs to last longer.
- Multi-fabric differentiated construction per body zone
- Performesh fabric on torso and sleeves for maximum breathability
- Compact fabric reinforcements on shoulders and wear areas
- Slim and clean fit, also suitable under technical layers
- Low weight, ideal for light or ultralight backpacking trips
Who and When
The Viper is designed for those who tackle technical treks on challenging terrain, high-altitude excursions, or mountaineering approaches where sweating on the move is the norm. The essential cut makes it comfortable on its own on hot days or as a base layer under a softshell on cooler outings.
