I love this hat for the sun protection on my neck!

I love this hat for the sun protection on my neck. I recently wore it several days in a row for multi-hour hikes. With the hat, I didn't have to sunscreen my neck or face, which is a huge upgrade in quality of life when hiking our otherwise outdoors. I would definitely recommend this!

Does what it promises

It claimed to be a sun protection hat aimed at running and it excelled in everything it promised. No sun burn on my (exceptionally) pale skin and it was quite comfortable. Wicked a lot of sweat on the forehead well too. I would definitely recommend this hat to others as a solid summer running hat

Game changer for fieldwork

The Sun Runner Cap is an essential piece of gear for my long days of ecological field research in the hot, sunny, arid deserts of Utah. The lightweight and protective material has kept my neck and ears from burning. The fitted cap and chin cord keeps my hat in place in windy conditions. The versatile design has also been crucial in decreasing my exposure to dusty roads, plant materials, and other allergens throughout the day, as I've been able to tie the cape to cover my nose. I may add Velcro to the cape to cover my nose more easily though. I definitely recommend this excellent product!

South rim to the Colorado river

A couple weeks ago, we hiked down to the Colorado river and back up in one day from the south rim of the Grand Canyon. 18 miles and 100° heat. We had to carry all of our water because the water stations were closed. I have been a fan of, a wide brim straw hat for my big hikes and backpacking. My son who does long distance running bought one of these hats and said he loved it so was some trepidation, I decided to give it a try. I didn't want to have a bad time on that hike. As it turned out, I loved it and that will be my new headgear. It was light and cool, and I was able to dip it in streams and put it back on my head a few times, I'm a fan.

Great fit for a big head!

I often have a hard time finding hats that fit having a 7 7/8 - 8 " fitted hat. sized head. This big boy fits great and provides great shade.

Solid Sun-Smart Hat!

Bought this hat for a little extra coverage in above-alpine and minimal tree-cover running zones. Comfy, breathable, and gets the job done. Pretty solid price too honestly.

Great for Trail Running in Sunny & Hot Weather

Living in SoCal and being an avid runner (both the road and trails), I decided that I need a good running cap with neck/face protection from the blaring sun - especially during the summer. After looking at all the various options available, I decided to go with this cap from OR and I can't be happier. It is exactly what I needed. The fit is spot on, is breathable and keeps my head cool, and provides the protection from the sunlight from my sensitive skin. Looks good as well! Highly recommended!

I would buy this product again

I give the Sun Runner Cap 5 Stars. I am a Melanoma Survivor, and this Cap gives me the protection from the sun that I need. Itstays in place, is cool and comfortable yet flexible for all of my outdoor activities. I am almost 80 years old and continue to be active, so I really appreciate having products that assist me in pursuing the things I love to do in the outdoors!
