Sunday Afternoon’s Technology

We’re hat experts. Lovers of the great outdoors. And we tinker until we get it right.

We know what it’s like out there, so we design our hats to be good companions for your adventures on or off trail, in the garden, out on the water, on the street, and in the sun. Wherever your path leads—whether it’s pushing the limits or simply passing the time – our designs and technologies will take you there in style and comfort.

  • The sun! Celestial ball of light and warmth! It’s hard to beat the enjoyment of a day in the sun, unless it’s a day spent in the shady pleasantness of a UPF 50+ hat. A rating of UPF 50+ is the highest sun protective rating achievable and means only 1/50th or less of UV rays are able to pass through, allowing you to diminish the sun, not the fun!

  • Get yourself a Sunday Afternoons insulated hat and keep the warmth in and the UV radiation out! Our insulated hats are constructed from wool felt and are water repellent, but still offer UPF 50+ protection, so you can stay outside in all of the elements. Protect yourself all year round, because the sun does still shine in winter!

  • UPF 50+

    Hats with high UPF protection offer the greatest sun safety. Sunday Afternoons hats are designed to protect in even the harshest sunlight, with sun hats rated UPF 50+ (the highest possible) and approved by the Melanoma International Foundation.
