Where do you find the plastic piece that connects the ends of the hatband? I searched online but I am not sure what to call it.
someone needs to just go ahead and weave a shirt out of paracord.
Here's my Tilley with a paracord band. My Browning Mako Pro blade is there too with it's own paracord tail.
I used small line to tie it on the hat in a couple places. If you get side release buckles, look for the ones made for pet collars-- they have a little curve built in. Straight ones will certainly work. I got some made for backpack sternum straps that have a whistle built in.
survival hat! now thats a good idea!
