Sun Tripper product video

Performance fabrics and a ventilated design ensure a comfortable fit and major style points. Smart and good-looking? This is a hat you can take home to meet mom!

Underweight for its features!

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: large

This hat is perfect for backpacking and a myriad of other uses. Weighs almost nothing. Its bill folds to let you stuff the hat in your pocket. It breathes, adjusts circumference (though not one-size-fits-all), allows a ponytail , provides sun protection, and has a hidden pocket for valuables. I've used it at the beach, hiking, and backpacking. Cost is reasonable. Certain colors were on sale!

Love these hats

  • Familiarity: I've put it through the wringer
  • Fit: Runs large

Love the SPF sun protection this hat provides for my every thinning hair. It keeps me comfortable while being out doors and protects my poor scalp. I get compliments on this every time I wear it.

My "Go-To" Hat

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I wear my Sun Tipper more then any hat in the Sunday Afternoons line. It works well in just about every situation throughout the day; work, shopping and kicking back...

Sunday Afternoons Sun Tripper Cap

Nothing better than pumping a little water on a hot, sunny Sunday, is there...!?

I hope they are wearing a pair of waterproof Bogs. I refuse to use the faucets of today as they are not zombie or apocalypse proof and when I get water from my well I always spill. Thanks to my favorite pair of bogs though my socks never get wet.

great fit, wicks away!

    The hat is a great fit and style. I'm a true medium and the hat fits great. The cord in the back is good if you're in between sizes. What I love is the wick away sweatband and how its breathable. The style isn't as deep as a military style hat, but its still a great cut. I wish the brim wasn't foldable so I could make the brim a little less straight across, but its still pretty cute.

    Just Right

      I purchased this hat after trying several other military style hats that Backcountry.com sells. I have medium to large head and find many hat sit to high on my head. It was close call between this hat the the Outdoor Research Radar Pocket Cap which sat lower on my head. I decided on this hat as it looks more feminine.
      There is also a small black cinch cord on the back on the hat which I find helpful as I am between a medium and a large.

      Nice little hat

        I like this hat. It is very well made and I like the material. I wish it was a little deeper however. The design of it makes it less complimentary than a castro hat.

        I found it...

          I've been looking for a cap like this for a long time. It's quite comfortable; design fits well on the head; headband is wide and comfortable; adjustible cord from the back give customized fit and can be adjust to windy conditions; material is light-weight; and two vents on each side for air-flow and circulation. Cap bill is foldable so you can pack it tight including your back pocket. I also like the style; simple and functional. A little more than what I expected to pay but worth the extra and the wait.


            This is a sweet cap! Foldable brim and ventilation definitely give it the one up other caps out there. I use mine to for both around town and out on the trail. I really like the folding brim cause I can actually just the hat keep in my back pocket.

            I was in between sizes when I bought mine. Opted for the Large. Cap sizes down pretty good.
