Multi-Layered Breathability for High-Output Adventures

​When you are moving fast and the temperature is rising, reliable ventilation is essential. The Montbell 3D Mesh Cap is engineered to keep you incredibly cool, utilizing an advanced multi-layered mesh fabric that maximizes airflow without sacrificing structure or sun protection. Finished with an innovative photo-catalytic treatment, this cap works just as hard as you do to keep sweat and odors at bay during long, strenuous days on the trail.

​Why We Love It

​At X-Boundaries, we know that multi-day treks and high-intensity hikes can take a toll on your gear—and your freshness. What we love most about this cap is its integrated photo-catalytic agent, which naturally neutralizes and reduces odors over time. Combine that active odor control with Montbell’s signature "Light & Fast®" design approach, and you have a 65-gram powerhouse that delivers lasting comfort and excellent sun protection with its generous 7.5 cm brim.
