Mens Summer Outdoor Breathable Sun Hat Cycling Fishing Sun Protection Fisherman Cap Travel Windproof Hiking Mountain Climbing

It's quite breathable and a bit roomy.

This hat is great! The fisherman's design really blocks the sun from all angles. It has plenty of breathable holes, so my head doesn't feel hot even under the blazing sun. Just a note, the beads on the string came off after a few days; they should be tucked inside the string instead of outside, as they easily come off when pulled.
