Description

The AENERGY TR WB HYBRID VEST is an ultralight men’ssleeveless vest designed by Mammut

It has been specifically developed to protect the bust from wind chill while providing active thermal regulation. Its hybrid construction combines windproof front protection with maximum ventilation at the back, meeting the needs of sportspeople during intense exertion in changeable weather.

The front is made of a tough, wind-resistant ripstop nylon fabric, protecting vital organs from gusts. The back panel, on the other hand, is made from a highly breathable, elastic material that allows perspiration to evaporate quickly, guaranteeing total freedom of movement. With a weight of just 66 g, this waistcoat is one of the lightest on the market, making it easy to forget when worn or stowed in a pocket.

Functionality is enhanced by a practical zipped chest pocket for carrying small items and reflective elements for night-time visibility. The adjusted cut (Athletic Fit) and elasticated bottom ensure a stable fit close to the body, preventing any aerodynamic flutter during sprints or fast descents. This product is part of a sustainable approach, using recycled polyamide and Fair Wear certified manufacturing.
