Crowned the king of hiking headwear for 2025, this remarkable hat offers unbeatable sun defense with its UPF 50+ rating. The cleverly designed brim shields your face without blocking your view of stunning vistas ahead.

What makes it truly special is the breathable mesh side panels that prevent overheating during strenuous climbs. The crushable, packable construction means you can stuff it in your backpack without worry – it springs back to perfect shape when needed.

Earning top marks from My Open Country’s editors, the Sombriolet strikes that perfect balance between protection and practicality. The foam-stiffened brim maintains its shape even in gusty mountain conditions, never flopping into your line of sight.

Foam floating in the crown means this hat actually floats if dropped in water – a lifesaver during river crossings! The adjustable drawcord ensures it stays put during scrambles, while TransAction headband technology wicks away sweat before it reaches your eyes.

Did you know Tilley tests their legendary hats by running them through washing machines and having elephants try to eat them? This isn’t just a hat – it’s an heirloom that comes with a lifetime guarantee.

The LTM6 features a secret pocket tucked inside the crown – perfect for stashing emergency cash or a spare key. Its 3/4-inch ventilation mesh around the crown creates constant airflow, preventing that dreaded sweaty head feeling on hot trails.

Columbia Bora Bora Booney II

Budget-friendly doesn’t mean compromising on quality with this trail favorite. The Bora Bora Booney II features Columbia’s signature Omni-Shade technology that blocks UVA and UVB rays, protecting your skin during long days under the sun.

Unlike bulkier options, this hat folds down to practically nothing, making it perfect for stuffing in a daypack pocket. The adjustable drawcord toggle at the back provides a customized fit for any head size, while the mesh vent panel keeps your head cool when temperatures soar.

Outdoor Research Swift Cap

Speed demons and minimalist hikers, rejoice! The Swift Cap weighs next to nothing yet delivers impressive UPF 40+ protection. The traditional baseball cap styling makes it a versatile piece that transitions seamlessly from trail to town.

The secret weapon? A built-in TransAction headband that pulls moisture away from your forehead before it can drip into your eyes. The dark underbrim reduces glare reflection when you’re navigating exposed ridgelines or crossing snowfields.

The North Face Horizon Breeze Brimmer

Adventure-tested in the world’s harshest environments, this safari-inspired hat brings serious protection credentials to your trek. The extra-wide brim creates a portable shade zone that follows you everywhere, while smartly placed ventilation prevents the greenhouse effect many wide-brimmed hats suffer from.

Crafted from recycled nylon, it’s as kind to the planet as it is to your skin. The moisture-wicking sweatband inside keeps your forehead dry even during heart-pumping ascents, and the one-handed adjustable drawcord means you’ll never lose it to sudden gusts.

Buff Pack Trek Cap

Ultralight backpackers count every gram, which is why the Buff Pack Trek Cap has earned cult status among distance hikers. Weighing just 1.2 ounces, it compresses to the size of an energy bar yet springs back perfectly when unpacked.

The flexible brim can be positioned exactly how you want it – up for better visibility or down for maximum sun protection. The fabric pulls sweat away from your skin at remarkable speed, preventing the chafing and discomfort that can ruin a long-distance journey.

Outdoor Research Sun Runner Cap

Transformation is the name of the game with this ingenious two-in-one design. Start your morning hike with the full neck cape attached for maximum protection, then simply remove it when trail conditions change or you reach shaded forests.

The lightweight fabric dries in minutes after creek crossings or surprise rain showers. A hidden cord lock at the back allows for perfect fit adjustments even with gloved hands during colder weather treks.

REI Co-op Explorer Hat

Channeling vintage National Geographic explorer vibes, this cotton-blend hat brings a touch of classic style to modern trails. Unlike pure synthetic options, the Explorer offers a softer feel against your skin and a broken-in comfort from the first wear.

The structured brim holds its shape in any weather, providing consistent protection without constant adjustments. An internal sweatband wicks moisture effectively, while the chin strap – often an afterthought on lesser hats – is actually comfortable enough to use all day without irritation.

Patagonia Duckbill Cap

Street style meets trail performance in this distinctive cap beloved by ultra-runners and fashion-conscious hikers alike. The instantly recognizable duckbill design isn’t just for looks – it provides extended sun protection without the bulk of a full-brimmed hat.

The entire cap weighs less than your smartphone and folds flat enough to slip into a pocket. Constructed from Patagonia’s legendary quick-dry fabric, it handles sweat and sudden downpours with equal aplomb, never weighing you down with absorbed moisture.
