Why We Love This

One K™ Defender riding helmets boast the perfect synergy between advanced technology and aesthetically pleasing design. This helmet features a polycarbonate and advanced ABS composite outer shell that’s tough but lightweight with a modern matte finish. It’s offered in both an oval shape and a round shape so that you can find the perfect fit for your head. You’ll love that the liner is moisture wicking, quick drying, anti-microbial, and washable to keep you cool, dry, and comfortable. Plus, the harness is padded for comfort and lined with easy-to-care-for synthetic suede to keep you as comfortable as you are stylish. It even has a Fastex buckle that makes taking it quick and easy to take on and off. Additionally, you’ll have plenty of ventilation with two side, two front, one back, and two center stripe vents for a total of seven vents. Last but not least, this helmet is ASTM/SEI F1163-15 certified, so you can have peace of mind that your head is in good heads. With enough features to appeal to those seeking everything a horseback riding helmet could offer, wrapped in a stylish package that traditionalists can appreciate, One K™ has the best of both worlds.

    One K Defender Matte Helmet is rated 4.8 out of 5 by 181.
    Rated 5 out of 5 by from Best Helmet Brand for a Great Price Purchased about a month ago - after attending a show and seeI got a teammate get thrown, it was decided I needed a better, safer helmet. I chose the matte navy- it is both beautiful and comfortable! The price was much lower than on other sites and I’m very happy with it!

    Rated 5 out of 5 by from Best Fitting Helmet for My Oval Head! I have a very hard time fitting my oval head. Most helmets put so much pressure on my forehead, that I get a headache. Then there is the fact that I can get a full 3 fingers up the side of the helmet. The fit has never worked for me until I tried the One K Defender Matte Helmet. I also love that it has so many air vents. The helmet has 2 side, 2 front, 1 back, and 2 center vents. Not to get personal, but I am a head sweater and these vents help immensely. I chose the easy-care matte but it also available in glossy. The harness is extremely comfortable. It has a synthetic suede lining, easy to adjust, and easy to fasten. It is nice looking and lasts for a long time. I like that the brim is not overwhelming and that the helmet itself is very stylish. It is great for the show ring, training, trail riding, and everyday use. I recommend this to anyone, especially if you ride in hot weather. I have had mine for just about 3 years now. When it is time for a new helmet, the One K Defender Matte Helmet One K will be my only choice!

    Rated 5 out of 5 by from Love the oval option, nice helmet! I had quite a bit of trial and error with other brands before I found the right helmet to fit me. I figured out that it was mostly because of the oval shape of my head, so decided to try the One K since they do have the oval option. I measure just a touch over 57cm, so at first tried the size Large Oval. This helmet was much too big for me, even with the strap snugged all the way up. I exchanged for the Medium Oval and it fits like a glove! Very nice helmet and I love SmartPaks exchange policy!

    Rated 5 out of 5 by from Favorite helmet I've owned so far! Love this helmet. It's comfortable and much cooler than my Charles Owen. It's nice enough to wear to most shows.

    Rated 5 out of 5 by from Best helmet! I catch myself wearing this helmet long after I've dismounted. It's like it's molded to my head. Lightweight, hugs my head. Can't say enough good things about this helmet. It was recommended to me and I'm so glad I bought!!

    Rated 5 out of 5 by from Exactly what I’ve been looking for I’ve been looking for the right helmet for myself for years....this is it! The long oval fits me great. I get headaches when I wear helmets and this one does not cause me any issues. It doesn’t put pressure on my temples which is great. The helmet tends to sit higher on your head so it relieves compression from that area. Ventilation is also AMAZING. I rode in 85 degree weather and my head didn’t sweat! Love this helmet.

    Rated 5 out of 5 by from Fits great! Love the oval option. Other helmets only offer a round fit which was uncomfortable. This one fits great!
    Date published: 2020-06-02
    Rated 5 out of 5 by from Perfect Fit! This helmet fits so well. I have a small head and a narrow face...the long oval fit perfectly.
