When the journey is rough and the weather is rougher, have a hat that holds up. Wrap the tape measure around the largest part of your head until the two ends meet at the center of your forehead just above your eyebrows. Firmly hold the tape mid-forehead with your finger, not too tightly or too loose. The goal is to determine precisely where your hat will sit for the most comfortable fit. Take note of the measurement from your measuring tape and use it to find your corresponding size on our hat sizing chart. If your measurement is in between sizes on the hat size chart, choose the next larger size. Even though our hat sizes are standard across the USA, there are various factors that can affect the fit of the hat, from the hats material to how much hair you have. This is all the more reason to go a size up  a slightly roomier hat is much more comfortable and easier to pad than a hat thats too tight and gives you a headache. Dont worry if you have a big head. We have large hats to help provide the perfect size for you from XXL to XXXL (many of our mens hats come in XL already). Mens hats are generally sized numerically or alphabetically, although there are some mens hats that come in one size fits most. These one size hats fit heads with a circumference of 21 to 23 (medium to large). Womens hat sizing is often one size fits most: the style is made in a standard size with the ability to suit head sizes ranging from 21 to 22 in circumference. While actual hat sizes may vary, many of these one size womens hats come with an inner drawstring or band that can be adjusted to keep the hat in place. Most one size hats for men and women come with an inner drawstring that allows you to adjust the fit. These inner drawstrings are usually found stitched into the sweatband itself with an extended piece of string or ribbon that you can tug. Pull gently to adjust the fit, which can tighten the hat up to two sizes. Many hats without inner drawstrings feature bands made of leather, elastic, or foam lining. If this is the case, you can still adjust the fit of the hat with sizing tape. This is the preferred method of adjusting hats because it maintains the shape of the sweatband and inner lining without any damage.
