Women's Cotton Linen Sun Hats UPF 50+

Natural fibers, reliable protection. Solbari’s collection of cotton summer hats combines breathable comfort with certified UPF 50+ sun protection. The range includes the Ultra Wide Cotton Linen Hat with its extended brim and ponytail-friendly fit, the Palm Beach style with a detachable chin strap, and the relaxed Vacation Bucket Hat, each blending relaxed style with practical coverage.

Made from a premium cotton-and-linen blend, every style feels lightweight, soft, and breathable for beach days, travel, and warm-weather wear. Despite its natural-fiber construction, each cotton sun hat is independently tested and certified to block at least 98% of UVA and UVB rays.

Selected styles carry the Skin Cancer Foundation Recommended Seal and are part of Solbari’s dermatologist-endorsed range.

Why choose a cotton linen sun hat?

Natural fibers offer lasting comfort in warm weather. Cotton and linen allow air to circulate more freely than many synthetic fabrics, helping keep the head cooler during extended outdoor wear. Linen is especially valued for its breathability, while the 80% linen and 20% cotton blend gives these hats a soft structure that shapes naturally to the head.

Gentle against the skin, these cotton sun hats for ladies suit those who prefer natural materials or want a more relaxed, resort-style feel. The Ultra Wide Cotton Linen Hat also includes an internal wire brim that can be shaped to suit your preferred look.

From beach holidays to everyday wear, cotton summer hats combine softness, breathability, and practical coverage. Explore more ultra-wide-brim hats for maximum shade.

Natural fibers, certified UPF 50+ protection

Not all natural fiber hats provide certified UV protection. Solbari’s cotton-linen hats are independently tested and certified to UPF 50+, blocking at least 98% of UVA and UVB rays.

Protection comes from the weave density and fabric construction, not just the fiber type alone. Solbari’s fabric blend has been specifically developed to meet the UPF 50+ standard, with protection that remains effective over time because it is built into the fabric's structure rather than applied as a coating.

Designed in Melbourne and worn in more than 100 countries, Solbari combines natural materials with trusted sun protection.

Solbari FAQs

To find the correct size cotton sun hat, measure your head circumference where a hat would naturally sit: across the mid-forehead and around the back, keeping the tape level. Cotton linen styles in the Solbari range are available in S/M and L/XL, with S/M fitting up to approximately 22.75"–23" and L/XL fitting up to approximately 23.5"–23.75" depending on the style. If you're between sizes, size up for comfort. Many styles also feature an internal drawcord or adjustment band for a more customized fit. See our Size Guide page for more information.

A cotton sun hat is a wide-brim or structured hat made from cotton or cotton blends for outdoor shade and sun protection. Solbari’s styles are independently tested and certified to UPF 50+, blocking at least 98% of UVA and UVB rays.

Not always. Many natural fiber hats are not UPF tested, whereas Solbari sun hats are certified to UPF 50+ for reliable protection. Learn more about UPF 50+ protection.

Yes. The breathable cotton-linen blend feels soft and gentle against the skin, making our cotton linen sun hats ideal for women with sensitive or reactive skin.

Yes. All our cotton linen summer hats are packable and designed to reshape easily after travel. Flexible brims and adjustable bands make them ideal for holidays and warm-weather trips.

Hand wash in mild soapy water, reshape while damp, and dry in the shade. UPF protection is built into the weave, so gentle washing will not reduce performance.

Yes, you should. Even when you wear a hat, sunscreen is still important for your face because UV rays can reach your skin from different angles. A broad-brim hat helps protect your face, scalp, ears and neck, but it may not fully cover areas such as the cheeks, nose, chin and lower face. UV rays can also reflect off surfaces such as water, sand, concrete, glass, and even light-coloured ground, reaching your skin from below or from the side.

For the best protection, use sunscreen on exposed areas of the face and pair it with a UPF 50+ hat, sunglasses, shade and sun-protective clothing. Think of sunscreen and a hat as working together, not as replacements for each other.
