Find the right fit

Measure head circumference at the widest point above your ears. Our fleece liners make underlayers unnecessary. But if you want to layer a beanie underneath, add half an inch to your measurement.

Our kids' styles accommodate growth with each size offering adjustable circumference up to maximum widths. Adult Arctic Chill hats fit heads up to 23.5 inches with dual crown and chin adjustments for precise fitting.

Check our sizing guide for hat measurements across age ranges.

Winter sun hat care instructions

Fleece-lined sun hats require gentle care to maintain warmth and UPF protection. Hand wash in cool water with mild detergent, avoiding bleach or fabric softeners that can degrade UV protection.

Air dry before storage. Never use high heat that can damage protective fibers. Water-resistant winter sun hats benefit from occasional reproofing treatments to maintain moisture-shedding properties.

Store hats in a cool, dry place during off-season months. Stuff loosely with tissue paper to maintain shape, especially for wide-brim styles that can lose their form when compressed.

Clean immediately after exposure to salt (from road treatments) or strong sunscreen to prevent fabric degradation.

Complete your winter sun protection

Pair your UPF winter sun hat with sun-protective sunglasses for comprehensive UV defense. Snow glare can be particularly intense, and snow reflects about 80% of UV rays, so you need eye protection.

Our kids' sunglasses feature impact-resistant lenses and comfortable frames that fit under hat brims. For adults, polarized options reduce glare from snow and ice surfaces.

Winter sun hats FAQ

What makes a UPF 50+ winter hat different from regular winter hats?

UPF 50+ winter hats use fabrics that block 98% of UV rays while providing warmth. Regular winter hats focus only on insulation without verified sun protection. A high UPF rating protects even when wet.

Can water-resistant winter sun hats go in the washing machine?

Hand washing preserves water resistance and UPF protection longer. If machine washing is necessary, use cold water, a gentle cycle, and air dry. Avoid fabric softeners that can compromise protective treatments.

What’s the difference between UPF and SPF?

SPF measures sunscreen effectiveness, while UPF measures fabric protection. UPF 50+ fabric blocks the same UV percentage as SPF 50+ sunscreen but won't wear off.

Can you wear sun hats in winter?

You can wear sun hats in winter, but you don’t want to wear your summer sun hat. Instead, get a sun hat with fleece lining and a weather-resistant shell.
