S (55 cm):Â For those who feel they have a smaller head than the average.
M (57 cm): This is our most popular size. We consider this size our ‘average’ fit.
L (59 cm):Â For those who feel they have a larger head than the average.
XL (61 cm):Â Our largest adult size offered. Available in select styles.
One Size: Our One Size option typically fits most adults. Our XL Lifeguard (60 - 65 cm) is only available in select styles and sold exclusively online. If our One Size Lifeguard is too big, consider a Big Kids Lifeguard which fits XS heads.
IN-BETWEEN SIZES?
If you are in between sizes, we recommend sizing up. Most Hemlock sized hats come with an interior size adjuster and foam filler tape, so you can reduce the size of your hat by 1 - 2.5 cm and add comfort at the same time.
NOT SURE OF YOUR SIZE?
Use our How to Measure guide to find your ideal size for comfort and style. Or, if you have a hat that fits you well, check the sizing on the tag. Then, find your Hemlock size using our size conversion chart above.
