Koloa Outdoor Hat with Sun Flap and UPF Protection

From the Break to the Trailhead

Some mornings start with a paddle out and end with a hike up a ridge. The sun climbs fast, the trade winds carry the smell of salt and wild ginger, and by afternoon you are ready for a shady spot and a cold drink. This hat was made for days like that, when the plans change halfway through and you still want to feel covered from the sun.

Picture a Poʻipū morning with the surf still glassy, followed by a slow walk along the shoreline and a stop at the trailhead before the heat builds. The wide brim keeps the light off your face, and the sun flap tucks away once the sun drops and the shade returns. It is the kind of everyday piece that rides along in the car and never feels out of place.

What Goes Into It

• Fabric: 75/25 poly/nylon ripstop
• Structure: Unstructured
• No Fly Zone insect repellant technology
• UPF 30+ sun protection
• Concealable sun flap
• Moisture-wicking sweatband
• Foam brim that keeps the hat afloat in water
• Koloa Thruster Surfboard logo printed on the back of the sun flap
• Adjustable shock cord at the crown
• Clip-on, adjustable shock cord
• Available in Olive Leaf with black logo and Stone with black logo

Every piece works together, so the hat feels at home whether you are paddling out, hiking inland, or running errands around town.

Fit and Sizing

This hat comes in two sizes. Small/Medium fits head sizes 7 to 7 3/8, and Large/X-Large fits head sizes 7 3/8 to 7 3/4. The adjustable shock cord at the crown helps you dial in a snug feel, so the hat stays put when the breeze picks up. Check the size chart if you are between sizes.

How to Wear It

Wear it with the brim level for full coverage on a long hike, or flip the sun flap down over your neck when the sun is strongest. Clip the shock cord under your chin on windy ridges, and tuck the flap away when you head into town. Pair it with a rash guard and board shorts for a full day on the water and the trail.

Care

Follow the care label inside the hat for washing and drying instructions. Air drying in the shade helps the ripstop fabric and the foam brim keep their shape over time.
