Live in the PNW. I've had this close to yr now and its fully functional. Summer is favorite but with light rain I keep the gore tex cover off for breath-ability screen in front as my head sweats. Heavy rain I definitely roll it out. So the fully functional description means it works in almost all weather conditions. Adjustable strap inside as I've had beanie, and buff's inside as to accommodate colder temperature changes. Several washes and still holds up the brim and fixture of the look and wear. Yes you can squish it for a short time, but takes more time to spring back over a longer period of time. Backpacking works well and rarely touches your pack.
