The Mammut Aenergy Light Cap is a lightweight men’s cap made for outdoor use, offering basic sun protection and moisture management during active days in the field.
Constructed from 100% polyester with recycled fibers, this quick-drying cap moves sweat away from your skin and dries rapidly when you pause for a break. Its regular fit provides a comfortable feel without slipping or pinching, and at just 43 grams it adds almost no bulk to your kit. Using recycled polyester also reduces the environmental impact compared to virgin materials, so you can feel a bit better about your gear choices.
