Never worn - too small for my husband. Size M "Guys snatch up The Crusher year after year because of its ability to spring back no matter how it gets crushed, stuffed, folded or smashed. And now we've retooled it for better cooling action – wind blows straight through the polyester mesh sides so you can keep a cool head. The structured mesh sides hold their shape better, too. Solid cotton top and 3" brim have UPF 50 rating to block searing rays. Wicking CoolDry® sweatband feels comfortable on your forehead. Polyester chin strap prevents "blow-offs" on windy days. If only you bounced back into shape as easily!"
