Men’s UPF 50+ Flap Neck Sun Hats

Men’s UPF 50+ Flap Neck Sun Hats

A men’s sun hat with a neck flap offers extra coverage for the face, ears and neck during extended time outdoors. Solbari’s collection of men’s UPF 50+ flap-neck and legionnaire sun hats is ideal for walking, hiking, fishing, gardening, travel, outdoor work, beach days and other activities where the back of the neck is regularly exposed to the sun.

Every Solbari fabric is independently tested and rated UPF 50+, the highest sun protection rating available for fabrics, helping block at least 98% of UVA and UVB rays through the fabric on covered areas. Flap-neck hats are a practical choice for men who spend long hours outdoors, have sun-sensitive skin or simply want additional coverage built into their everyday sun hat. The UPF 50+ fabric helps protect the skin it covers from UV radiation.

Men's Sun Hats With Neck Flap for Outdoor Coverage

A men’s sun hat with a neck flap provides coverage beyond what a standard cap offers, helping to protect not only the face but also the ears and back of the neck. It is a useful option for men who spend extended time outdoors and want extra coverage built into their hat. Hats help protect the areas they cover or shade. Sunscreen should still be applied to exposed skin, including areas of the face not shaded by the hat, as UV radiation can reflect off surrounding surfaces.

More Coverage Than a Standard Cap

A standard cap mainly shades the face, while a flap-neck hat extends coverage to the ears and neck. This added sun protection is particularly useful when turning away from the sun is not always possible, such as while fishing from a boat, walking along an exposed trail, gardening or working outdoors. The right choice depends on your activity, the amount of time you spend outside and the level of coverage you prefer.

Verified UPF 50+ Rating, Not Just a Label

Born in Melbourne, Australia, Solbari was created in response to one of the world’s strongest natural ultraviolet environments. Every UPF 50+ fabric is independently tested by accredited laboratories, so the sun protection rating is verified rather than self-declared.

Men's UPF 50+ Flap Neck Hats for Fishing, Hiking and Travel

Long days outdoors often mean more sun exposure, fewer opportunities to reapply sunscreen and greater exposure from reflective surfaces such as water. A flap-neck hat provides additional neck coverage, helping keep you comfortable during extended time outside.

Built for Long Sunny Days Out

Men’s hats with a neck flap are ideal for fishing, hiking, walking, travel, gardening and outdoor work. They are especially useful when you spend hours outside, providing consistent coverage as the sun moves across the sky throughout the day. A men’s fishing hat with a neck flap is particularly well suited to time on the water, where reflected UV radiation can increase overall exposure.

Pairing Your Hat With a Complete Sun-Smart Routine

A flap-neck hat works well with UPF 50+ shirts, arm sleeves and hand covers to extend coverage across more of the body. Sunscreen is still recommended for exposed skin not covered by the fabric of your hat or clothing.

Solbari FAQs

A men’s sun hat with a neck flap is a UPF 50+ hat with an attached flap that extends coverage across the back of the neck and ears. Compared with a standard cap or many wide-brim hats, it provides additional coverage for areas often exposed during long periods outdoors.

Choose a neck-flap hat when extra coverage for the neck and ears is important, such as during fishing, hiking, outdoor work or travel. A standard cap mainly shades the face; a wide-brim hat adds coverage around the face and ears, while a flap-neck hat extends coverage across all three areas.
