I'm slowly building my bushcraft kit and I have the essentials like water bottles and other things taken care of.
At the same time I'm also preparing a BDK (Bad Day Kit) or a BOB if you want to call it that. One part of it I know little to nothing about is a head cover or something to keep dust out and filter the air a little bit if there's a dust storm or something.
I've looked at Shemaghs and those neck wrap thingies and I like the multi-functionality of a Shemagh but I don't have any experience with them. I'm looking for some opinions on what to invest in or what I should try, anything is welcome!
