    Shop Oilskin / Waxed Cotton Hats Collection

    Oilskin — also sold as waxed cotton — is the only genuinely waterproof material we make hats from. Tightly woven cotton is saturated with a wax and oil finish that fills the gaps between the fibres, so water beads on the surface and runs off instead of soaking through. It's the traditional Australian answer to a wet day outdoors, and it still works better than most technical fabrics.

    The trade-off: oilskin is heavier and less breathable than wool or straw, and the finish wears off at the creases over time. That's fixable rather than fatal — re-treat it with a wax or a waterproofing spray when water stops beading, and the hat goes back to new.

    Never dry oilskin near heat, and never machine-wash it — the hat care guide explains why. For light rain only, wool is lighter and cooler: see our wool outback hats. Every hat here is handmade, carries our limited lifetime guarantee against manufacturing defects, and ships with two free size inserts so you can fine-tune the fit. The guarantee also includes a 50% off code to replace the same hat if yours is ever lost or stolen. Free US shipping on orders over $79.

    • Waterproof Hats for Wet Weather Adventures
      Conner's oilskin and waxed cotton hats deliver reliable water resistance for fishing, hiking, outdoor work, and travel through unpredictable weather. These hats shed rain effectively while offering sun protection, making them ideal for extended outdoor exposure in wet conditions.

    • What Makes These Hats Different
      Oilskin and waxed cotton hats use a traditional waterproofing method: cotton fabric treated with oil or wax creates a barrier that causes water to bead and roll off the surface. This treatment, originally developed for sailors in the 1800s, provides water resistance without synthetic coatings. While not as breathable as modern technical fabrics like Gore-Tex, these materials offer durability, a distinctive appearance that improves with age, and can be re-waxed to maintain water resistance indefinitely.

    • Best Uses
      These hats work well for fishing in wet weather, hiking through rain, outdoor work requiring weather protection, ranch and farm activities, travel to rainy climates, and daily wear in cool, damp conditions. They're less suitable for high-intensity activities in warm weather due to limited breathability.

    Performance Characteristics

    •  Water resistance:Effective in rain and wet conditions; water beads off the treated surface rather than soaking through
    • Breathability: Moderate—the wax treatment reduces airflow compared to untreated cotton, making these hats best suited for cool to moderate temperatures or lower-intensity activities
    • Sun protection: wide brims shade face, ears and neck; hats with open mesh, vents or brims under 2.5 inches carry no UPF rating
    • Durability: Heavy-duty cotton construction withstands years of use; re-waxing restores water resistance as needed
    • Break-in period: Fabric softens and develops character with wear while maintaining protective qualities

    • Material Comparison: Oilskin uses oil treatment (linseed or similar oils mixed with paraffin) applied to tightly woven cotton. The result is slightly heavier fabric with a distinctive texture and smell that fades over time.
    • Waxed cotton uses paraffin or beeswax applied to cotton canvas. The wax is melted into the fibers using heat, creating a smoother finish than oilskin. Waxed cotton typically feels less stiff and has no odor.

    Both materials provide comparable water resistance and require periodic re-treatment to maintain waterproofing. The choice comes down to personal preference for texture and appearance.

    FAQs

    Oilskin and waxed cotton hats are water-resistant. They handle rain showers and wet conditions effectively: water beads on the surface and rolls off rather than soaking through. However, in prolonged heavy rain or with strong wind, water can eventually penetrate the fabric, especially through seams. For most outdoor activities such as fishing, hiking, ranch work and travel, these hats provide useful protection from rain. For more demanding conditions, check the product page for the specific hat's water-resistance details.

    Moderately breathable, but less so than untreated cotton or modern technical fabrics. The wax or oil treatment that makes these hats water-resistant also reduces airflow. This means they work best in cool to moderate temperatures or during lower-intensity activities. In warm weather or during strenuous activity, you may feel warmer than you would in an untreated cotton or mesh hat. The trade-off is weather protection—if you prioritize staying dry in rain, the reduced breathability is manageable. For high-intensity activities in warm conditions, consider hats with moisture-wicking fabrics or ventilation features instead.

    For regular cleaning, wipe the hat with a damp cloth and avoid machine washing or fully soaking it. When water stops beading on the surface, re-proof it with Nikwax, which is suitable for cotton. Follow the product instructions and let the hat dry naturally before wearing it. Re-proofing helps restore water resistance, and proper care can help extend the hat's life.

    The difference is in the treatment method, not the performance. Oilskin uses oil (typically linseed oil mixed with paraffin) soaked into tightly woven cotton. It has a slightly heavier feel, a distinctive texture, and a mild odor when new that fades with use. Waxed cotton uses paraffin or beeswax applied to cotton canvas and melted into the fibers with heat. It has a smoother, glossy finish and no odor. Both provide comparable water resistance and durability. Choose based on your preference for appearance and texture. Functionally, they perform similarly.

    Yes. Some of Conner's oilskin and waxed cotton hats have UPF ratings; other styles provide shade only. Wide-brim styles provide shade for your face, neck, and ears. Hats with open mesh, vents, or brims under 2.5 inches carry no UPF rating. Many of our hats are UPF rated, so check each product page for its rating. The combination of water resistance and shade makes these hats versatile for variable weather, such as rain in the morning and sun in the afternoon.

    With proper care, oilskin hats can last 10 or more years, depending on use and care. The heavy-duty cotton construction is durable, and re-waxing the fabric as needed can help maintain its water resistance. The fabric develops a worn, personalized appearance over time while maintaining its protective qualities. Conner Hats' Limited Lifetime Guarantee covers workmanship failure for purchases from connerhats.com: during the first 12 months, it provides a free replacement of the same style, size, and color, with shipping paid. After 12 months, a 40% off replacement code applies, with shipping not included. Material degradation qualifies for a 30% off code. If the hat is lost or stolen, the guarantee offers 50% off the same hat.

    Not ideal for hot weather or high-intensity activities. The wax treatment that provides water resistance also reduces breathability, which can make you feel warmer. These hats work best in cool to moderate temperatures (below 70°F / 21°C) or during lower-intensity activities. If you need a hat for hot, sunny conditions, consider Conner's straw, raffia, or mesh hats instead. They offer better airflow. Reserve oilskin and waxed cotton hats for cooler, wetter conditions where weather protection is the priority.
