MAMMUT Runbold Hat Nebla - Lightweight Outdoor Hat, UPF 50+, Foldable Brim, Moisture-Wicking

This featherlight outdoor hat delivers serious sun protection with UPF 50+ fabric and a foldable brim, making it an essential companion for sunny hikes and travel. Weighing just 60 grams, it packs down small and dries quickly, while the stretchy shell and integrated sweatband keep you comfortable mile after mile.

Advantages

The Runbold Hat blocks harmful UV rays with a UPF 50+ rating, shielding your face and neck during prolonged exposure. Its four-way stretch blend of 85% polyamide and 15% spandex ensures a secure, comfortable fit on any head shape. The 100% polyester lining and internal sweatband wick moisture away from your forehead, preventing drips and keeping you cool. Laser-cut ventilation holes along the crown promote airflow on hot, humid trails. When not in use, the foldable brim flattens the hat to a compact size, making it easy to stash in a backpack or suitcase. The quick-drying construction and bluesign® certification reflect MAMMUT's commitment to responsible manufacturing.
