Hat & Size Guide

We want your SmileReef surf hat to feel just right — secure, comfortable, and protective. Use this guide to find your perfect fit.

How to Measure Your Head

1. Take a flexible tape measure (or a piece of string you can measure later).

2. Place it around your head, just above your eyebrows and ears — where your hat would naturally sit.

3. Make sure it’s snug but not tight

4. Note the measurement in centimeters (cm).

Fit Tips

  • Your surf hat should feel snug but comfortable — secure enough to stay put while paddling or wiping out.
  • If you’re between sizes, we recommend sizing up for comfort.
  • Integrated helmet adds a layer of protection but doesn’t change the fit — just more peace of mind!

Care Tips for Your Hat

  • Rinse with Fresh Water After Every Use

Salt water, while a surfer's natural habitat, carries minerals and salts that can embed in the fabric of your hat, leading to discoloration and degradation over time. After your surf session, give your hat a thorough rinse under fresh, cool water. This simple act washes away those potentially damaging compounds, significantly reducing the risk of color fade and material wear.

  • Avoid Drying in Direct Sunlight

Although it's tempting to speed up the drying process by placing your hat in direct sunlight, prolonged exposure can have adverse effects. The sun's UV rays can break down fabric fibers and cause the vibrant colors of your hat to fade much faster than they would otherwise. Instead, opt for drying your hat in a shaded area. This method ensures your hat dries efficiently without compromising the integrity of the fabric or the brightness of its colors.

  • Loosen the Strap After Use

Relieving the tension from the strap after use helps maintain the durability of the tightener, ensuring it lasts for many surf sessions.

  • Hand Wash Every 3 Months

Salt water, sunscreen, sand, and sun can wear on your hat. To keep it fresh, hand wash every few months:

  1. Remove the fabric cover (velcro inside).
  2. Soak in lukewarm water with mild detergent for 15 min.
  3. Gently scrub with a soft towel, rinse well.
  4. Press out water (don’t wring) and air dry in the shade.

This simple care keeps your hat clean and lasting longer.
