Crazy Idea Shirt Viper

"The T-Shirt Viper is designed for demanding trekking, with a lightweight fabric and a minimalist and clean look. It is constructed from differentiated fabrics that optimize protection and breathability in every area of the body, giving it a higher level of protection and functionality: The entire upper body and sleeves are made from performance fabric that is breathable, quick-drying, odor-resistant and UV-resistant, while the underarm area is made from an even lighter and more breathable mesh. Its technical nature is underlined by reinforced shoulder straps with a soft but durable fabric and carbon fiber yarn to protect the backpack from wear and tear."
