Overview
TOP-EX's wide brim hat pairs a 3.1 inch brim with a 9.4 inch neck flap and a contact-cooling fabric in the sweatband and crown, rated UPF 50+ and offered in 4 sizes for larger or smaller heads.
The cooling claim here is passive, a contact fabric rather than any fan or water activation, so the effect depends on that fabric touching skin rather than active airflow. Sizing is a real differentiator too, with 4 measured options instead of the single one-size fit common in this category.
- UPF 50+ rated, blocks 98% of UV rays
- 3.1in brim with 9.4in neck flap
- Contact-cooling fabric, no water needed
- 4 precision sizes with adjustable drawcord
Who it's for
Hikers, anglers, and outdoor workers with larger or smaller than average heads who want measured sizing plus a full neck flap for coverage. Less suited to anyone who wants a hat with active fan cooling.
Pros and cons
- UPF 50+ blocks 98% of UVA/UVB rays
- 9.4 inch neck flap for full coverage
- 4 sizes instead of one-size-fits-most
- Brim rolls or folds for packing without losing shape
- Cooling is a passive fabric effect, not active airflow
- Correct size selection matters more than with adjustable one-size hats
Performance notes
The contact-cooling fabric in the sweatband, crown, and neck flap is meant to feel cool against skin without needing water, while 6 mesh eyelets add airflow and a moisture-wicking lining manages sweat. The brim holds its shape with a semi-rigid structure and can be rolled or folded for packing.
