Men's 4F trekking waistcoat navy blue H4Z22-KUMP001 (H4Z22-KUMP001)

Discover a new definition of comfort and functionality with the men's trekking vest 4F KUMP001 – the perfect companion for every outdoor adventure. 

Starting with its unique design, the 4F KUMP001 vest stands out with its synthetic filling, which is a key element of its functionality. It is not only an alternative to traditional down but above all an innovative solution providing optimal thermal insulation. Thanks to this, even on cooler days, the vest maintains the ideal body temperature, allowing comfortable trekking or other outdoor activities.

The outer material of the vest is equipped with hydrophobic impregnation. This is a key advantage for those who are not afraid of changing weather. The hydrophobic layer effectively protects against moisture, ensuring dryness and comfort even during unexpected rain.

The main closure of the vest is secured with an internal flap, which provides an additional barrier against the wind. This detail significantly enhances comfort, especially in mountain conditions where the weather can change rapidly.
