DESCRIPTION
The Viper is a technical trekking t-shirt by Crazy built on a simple but effective principle: using different fabrics in the areas of the body where maximum breathability is needed and where greater sun protection is required. The result is a garment that adapts dynamically to the 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 exposure to UV rays or contact with harness and backpack are instead made of a more compact fabric, designed to offer protection and abrasion resistance where the shirt needs to last longer.
- Multi-fabric construction differentiated by body area
- Performesh fabric on the 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 outings with a light or ultralight backpack
For whom and when
The Viper is designed for those who tackle technical trekking on challenging terrain, high-altitude excursions, or mountaineering approaches where sweating while moving 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.
