Any Seattle Mariners fan will look stylish sporting this distinctive Classic Style hat. With a six panel construction (made of six separate panels that were then assembled together to form the body of the hat) this quality baseball hat takes after a popular style. Each panel was made of cotton twill. Even better, this Mariners MLB hat fits both youths and adults. This is great for any sports gift giver who doesn’t know the hat size of the lucky fan, and is ideal for young fans who don’t want to buy a new hat every time their head grows. The Mariners baseball hat is for ages 10 through adult (or hat sizes 6 7/8 – 7 ˝, you people who know sizes). The adjustable back tab means the wearers can fine tune the sizing to their preference, and that kids can adjust the hat when their heads grow.
