When you are going about the business of life, spending time outdoors, you might want a little bit of shade on your face and neck. A good way to get this shade is with a hat, preferably one with a wide brim to shield you from the sun's rays. A good example of this is a boonie hat. Historically, boonie hats (also known as bush hats) were used by the military for the purpose of camouflage. Around the brim of a boonie had is what is known as a 'foliage ring.' This is a continuous band of fabric sewn at brim level. Despite this fabric being continuous, it is attached to the brim at different intervals to create loops through which foliage could be placed to act as additional camouflage. Something else those loops are good for is the holding of paracord.
If you have not yet thought of carrying paracord on your head, now is the time to consider it. The width of the foliage band on most boonie hats is just begging to be accessorized with paracord, plus it is a convenient, out of the way place to carry paracord while adding an interesting look to your hat. The weight of adding paracord to your hat band is not substantial enough to weigh you down and cause harm, but if you have an especially sensitive neck due to injury or anything of that nature, adopting a lighter knot method could work better for you than, say, wrapping your hat in a king cobra.
The method I adopted to cover the foliage band of this boonie hat is the old standby that is the cobra stitch (aka Portuguese Sinnet or Solomon Bar). The reason for choosing this is because it could easily be tied to lay flush against the band while at the same time acting as a subtle accent instead of an overpowering one. Every few inches or so, when tying a knot, I simply pulled the paracord through the boonie hat's foliage band to attach it to the hat. I did not want to do it so often that it would be difficult to remove if the need arose, but I also did not want it to be constantly moving and lose its shape. Thus, the end result was passing the cord through every 6th loop or about every six inches.
What I now have is a boonie hat with a paracord band that I can use if I ever find myself in a pinch. Since the hat band is of reasonable size, I now have more than 20 feet of paracord wrapped around my head any time I don this hat. If you, too, want to have a sizeable amount of cord to easily carry with you, consider adapting paracord to work for you as a hat band on not just a boonie hat but any type of brimmed hat compatible with the addition of a band.
