By far our lightest and one our most popular sun hats is out vented, Kanga Cooler hat! Despite the venting, the leather is remarkable waterproof which can come in handy! This hats is very comfortable and stylist and is trimmed out with our Coolmax sweatband and also includes a leather sweat/sun block patch at the front (for those lacking a little hair will appreciate this additional sun protection!). PS. Not one kangaroo was killed to make this hat....they were all road kills as Australians are really bad drivers! FREE SHIPPING in U.S.A. Any questions?
