    One K Defender Suede Helmet is rated 4.8919 out of 5 by 37.
    Rated 5 out of 5 by from Great riding helmet Helmet looks great and fits great. Only minus is that the chinstrap leaves a black shadow (beard) on my face after wearing it for an hour or so. Hope this stops the more I wear it.

    Rated 5 out of 5 by from Great Helmet! I spent a long time debating which helmet I wanted and thought I wanted a Charles Owen. However, when I tried them on in the store I found that the C.O's hit my ears and were not comfortable. So, I tried the One K. It is wonderful! It does not hit my ears, and the back goes down far enough that I feel protected. It is very comfortable and is light. I can't comment on how hot it is as it's the middle of winter. I do not think it will be too hot though. Additionally, the liner is removable and can be laundered--a big plus. Many helmets nowadays do not allow that.

    Rated 5 out of 5 by from Love this helmet! I absolutely love this helmet! It's super comfortable, stylish and fits my hard to fit head! The helmet feels well made and sturdy, unlike some of the lesser expensive models. I love that the liner can be removed to be washed or replaced as needed. The size does run small, as I wear a medium in this brand, but usually a small or extra small in other brands like Tipperary.

    Rated 5 out of 5 by from Beautiful Helmet I bought this helmet s an upgrade from my plastic schooler and it was the best upgrade ever, i recently realized i needed to have better equipment for riding as i will be doing it 4 times per wee. i knew i needed more protection and augthough i felt bad because i had gotten and ovation 2 months before the one-ks. previously i had my hear set on a CO skull cap, this one was kind of small because i was in between sizes, this helmet had definetl been the best one ive had i like....... EVER.

    Rated 5 out of 5 by from Perfect Fit Purchased for my 12yr old daughter. She says its the best fitting helmet she has had. Prior to this she had the more expensive Charles Owen and I was a bit reluctant as this helmet is more reasonable priced. A few of the girls at the H/J show barn we board had this helmet already and have had nothing but great things to say about it. The helmet looks and feels just as well made and put together as the more expensive helmets. My daughter loves it and I she has recommended it to all the girls at the barn. Shopped around and Smart Pak had the best price and of course free shipping to the barn or my house. Love IT... thanks Smart Pak

    Rated 5 out of 5 by from Looks snazzy! Runs a tad large. I was in between a medium and large. Went for the medium, it fits perfectly! Love the look.. and it makes my oval head look good!Was fighting acne due to sweat..hoping the removable anti microbial interior will help with this issue.

    Rated 4 out of 5 by from Great helmet I bought this helmet this summer and I'm very happy with it. The chin strap is awkward and plastic, but I've delt with it. Another thing I don't like is that the roundness of the brim and how there isn't a division of some sort. I love how light and ventilated it is and the removable inside. Overall great helmet that has nicely held up although I haven't fallen off with it.

    Rated 5 out of 5 by from Great looks and comfort! I bought this because I wanted a nice-looking helmet for showing but could not justify the money for a Charles Owen. I was looking for nice styling with plenty of ventilation. I was pleasantly surprised by how comfortable it is! Note on sizing - I ordered a small but was thinking i would be borderline with a medium. The small fits perfectly, so that might mean that it runs large?

    Rated 5 out of 5 by from Great fit and style! I tried on a lot of helmets and none of them were fitting my oval head quite right. It was down to the Samshield and One K. I liked the look and price the the One K. The chin strap takes a little getting used to but this is a great helmet!

    Rated 5 out of 5 by from I'm very happy! I love this helmet! Previously I had over heating issues, but this helmet eliminated the problem. I had many compliments on how it looks too.

    Rated 5 out of 5 by from Best value and fit (for me) I cannot say enough good things about this helmet. It's lightweight, well made, very low profile, cool, and most importantly it fits me. I did not have success with the COs or even GPAs. Very very very happy that these are an option. The price makes it even better.

    Rated 5 out of 5 by from GREAT HELMET Love this helmet. Great fit. Really like the removable liner. Lots of air vents to keep my head cool. Even at 100 degrees I'm comfortable riding in this helmet.

    Rated 5 out of 5 by from Comfortable, attractive, and cool I'm thrilled with this helmet's fit, comfort, quality, and good looks. First ride wearing it was on a very hot day and my head did stay remarkably cooler than with my old helmet. Can't rate the durability yet, but it looks extremely well made and I expect it to hold up.

    Rated 5 out of 5 by from wishes do come true Finally, a helmet for all those round-headed people out there! Everything I tried was too oval for me until this one. Now I'm not resigned to using a schooling helmet or a helmet that doesn't fit for shows. I was afraid that the recommended size would be too snug and give me a headache, not being used to equal pressure all the way around my head, but never a problem. I also wondered if the ventilation would compare to my schooling helmet and I couldn't tell the difference. I also appreciate that the liner can be removed to wash - no stinky head for me! Yeah, the chin strap sits in a weird place, but I'll get over it. I can see myself collecting more colors...

    Rated 5 out of 5 by from Most awesome helmet, EVER! I received this as a long wished for gift. I have a jack-o-lantern sized head which is also very round. Finding well fitting helmets is almost impossible, but the One K helmet fits like a glove! I also appreciate the balance of the helmet. I don't feel that I must crane my neck to see where I'm going and it is lighter weight than my older helmets. An outstanding feature is the ability to remove and wash the liner. No more having a helmet that smells like a wet wildebeast. You only get one head, protect it!

    Rated 4 out of 5 by from Very good-looking, but S/M/L sizing doesn't cut it This is a fabulous-looking helmet. I mean, REALLY good looking. Extremely flattering. But these helmets that only come in S/M/L sizes, rather than 6 7/8, 7, 7 1/8, etc. just do not fit as well. I know it's cheaper for the manufacturer to do the S/M/L sizing, but I can't get a perfect fit this way. The M is slightly tight, which is why I returned it. Having tried on many S/M/L helmets, I know the L would be slightly big. I'd rather spend a little more money to get a helmet with what I think of as "real" sizing (when I started riding, number sizing was all there was.) I think the companies that have stuck with number sizing know what they're doing. I returned this helmet in favor of the IRH Elite EQ, which is number-sized; size 7 fits me perfectly, and it's the most comfortable helmet I've ever worn. I really like the way that helmet looks and I'm happy to keep that one, but I admit the One K looks just slightly more flattering. However, the IRH has a breakaway visor, while the One K has a fixed visor. I believe breakaway visors are safer.

    Rated 5 out of 5 by from Love this Helmet! This is my favorite helmet that I've ever had! It not only looks really nice, it has good ventilation and is comfortable to wear. The liner system gives you a very customized fit which was necessary for me. I have a wide head, so I had to get a larger size and a smaller liner to make it a perfect fit. I've gotten many compliments on it too.

    Rated 5 out of 5 by from Beautiful helmet for show But..... It doesn't fit an oval head. I ordered a triceps instead

    Rated 5 out of 5 by from In Love! I bought this helmet because it was on sale and I am so glad I did! It looks great, fits me well, keeps me cool and I have gotten so many compliments on it. One of my trainers even went out and got one after seeing mine. Made in the same factory as the Samshields, for half the price. Great value.

    Rated 5 out of 5 by from Great Fit I purchased this a few weeks ago and I'm so much more comfortable. The chin strap is in an awkward place for me, but the rest of the helmet fits wonderfully.

    Rated 4 out of 5 by from Cool helment man!! I purchased this helmet because I tend to over heat while I am riding and also based on the other reviews. I have only ridden in the helmet once but it was very comfortable and well ventilated. I also like the look of it and received immediate compliments. I chose the all black version. My only negative is the chin strap which tends to sit a little closer to the chin than my other helmet. My trainer, who also owns one, says I will get used to it and the benefit of the coolness of it would outweight the chinstrap. I wear a 6 3/4 normally and purchased the small. It fits snug but will stretch out to perfect! I also like the removable washable liner!

    Rated 5 out of 5 by from Very Comfortable! The Medium was a bit tight even tho in my head sizerange. The large is perfect with the medium insert. Nicelooking too. I do wish Smartpak would carry the extra inserts.
