SLOGGERS makes this hat for gardening apparel but the weave is beautiful, tight, and resilient. Material is 65% PAPER and 35% POLYESTER with a headband/chin strap of manmade fiber to resemble leather. I have been a fan of Insect Shield garments for several years and the addition of UPF 50+ rating means protection from almost 100% of the harmful UVA and UVB rays.
