One K Defender Suede Helmet is rated 4.8 out of 5 by 94.
Rated 5 out of 5 by from Love this Helmet! Time for a new helmet, tried a few of models I knew and decided to give this one a try. Just what I was looking for. I ride in the heat mostly, very well vented, comfortable, lining comes out for washing and sleek and lovely for the show ring. I am very happy with it. Even easy adjustable strap for tweaking once you have it on.

Rated 5 out of 5 by from a hidden gem! Before another boarder mentioned OneK I had never even heard of this helmet before but now that I have one of my own theres no way I'm going back. I have had this helmet for months now and it is just like new thanks to the washable liner and the suede being baby-wipable! The air vents are the best I've felt and the helmet looks sharp and is superb in comfort. I love love love the cushioned straps, adjustments, and removable, WASHABLE, padded antimicrobial helmet liner most of all.

Rated 5 out of 5 by from Every feature is Excellent! After going back and forth on a new helmet a few times. This one was perfect! Cool was very important to me and the vents are the best. Lightweight so you don't even think about it. Perfect fit. Washable liner. And the best was with all the vents it looks perfect for the show ring and the price is super and would rank it with the much more expensive ones. Happy rider!

Rated 4 out of 5 by from Features are great! This helmet had everything I was looking for. Plenty of vents, washable liner, and protection at the base of the skull, turned out to be sharp looking as well.

Rated 4 out of 5 by from A bit too big It is really a beautiful helmet and wish it came in a smaller size. The small was still way too wiggly on my head even with the chin strap adjusted all the way down. I still gave it four stars because it really is a nice helmet, it feels light, looks beautiful, and is pretty reasonably priced. Unfortunately, it just didn't work for me and I had to send it back.

Rated 5 out of 5 by from Coolest helmet I bought this helmet after another boarder highly recommended it. My head sweats A LOT and I was looking for something cooler. Well I found it! I can actually feel air coming through the vents and when I get done riding I don't have to wring the sweat out of my hair. I love the fit and look of the helmet and will definitely get another one for showing!
Date published: 2015-09-20
Rated 5 out of 5 by from Very happy with it! Bought this to keep nice for shows and I'm very happy with it. Nice fit, very comfortable and well padded. It's not too bulky and lighter than I expected it to be. Seems like a great buy for the price!

Rated 4 out of 5 by from One K Defender helmet Love the vents. Even though it looks like the liner covers the vents inside the helmet, the air still flows through. Only slight issue I had was that the chin strap has a forward slant and wanted to slide forward over my chin. As it's breaking in, it's now staying put.

Rated 5 out of 5 by from My favorite helmet This is my second One K helmet. I got the second one because of the National Helmet Awareness day and it doesn't hurt to have a spare on hand. Love the fit of this helmet
Date published: 2015-08-25
Rated 4 out of 5 by from Attractive helmet, good fit! Purchased this for my younger sister as her "upgrade" helmet - seems to fit well, attractive style. Nice that the liner can be changed out.
Date published: 2015-08-25
Rated 4 out of 5 by from Nicely Ventilated I bought this after my ayr8 started to smell so bad and be so moist I thought it was going to start its own ecosystem. I wish I had bought this instead of my ayr8. The ventilation is great and makes my face look very slender, I will most definitely be using OneK for a long time to come.
Date published: 2015-08-24
Rated 5 out of 5 by from Love the style I have been looking at the helmet for a year and even tried on on at a local store so when it was offered at a lower price during helmet safety day I bought! Absolutely worth the price and the medium fit is perfect!
Date published: 2015-08-24
Rated 5 out of 5 by from Love this helmet! The helmet fit well and is very comfortable. Unsure of durability since I have only had it a few months, but suspect it will hold up well.
Date published: 2015-08-24
Rated 5 out of 5 by from The most comfortable helmet! I bought this helmet for my 18 year old daughter. She had done research on helmets and this is the one that she chose. She was not disappointed with her choice! She claimed that this was the most comfortable helmet she had ever had for both showing and everyday riding. My daughter has been riding and showing for over 10 years. She highly recommends the One K Defender Suede Helmet for comfort, safety, and style! You will not be disappointed! * We did not rate the durability of the helmet because we have not had it very long and I hope we never have to put it to a test. (if you know what I mean!)

Rated 5 out of 5 by from Great helmet for the price I bought this helmet a few weeks ago. It's fantastic. So lightweight and comfortable.
Date published: 2015-06-06
Rated 5 out of 5 by from Very nice helmet! This is a very nice looking helmet; it's a little higher profile than I would have liked, but the fit is outstanding. So comfortable I almost forgot it was on and it didn't move at all. Nicely ventilated, kept me pretty cool on an 89 degree day.

Rated 5 out of 5 by from Fits great and is very comfortable I bought this helmet about 6 weeks ago. I love it! Not only does it fit my head comfortably, it is a very nice looking helmet.

Rated 5 out of 5 by from Love this helmet I bought this same helmet but with bling for season. Loved it so much I bought this one for schooling. It's comfortable and doesn't make me my head look huge! Great purchase !!
Date published: 2015-04-16
Rated 5 out of 5 by from Loved the dove grey helmut. I ordered a medium as I have an older One K of the same size. This felt a tad bigger. The helmut is great. For some reason One K in its packaging refers to 3 additional pads that can be added to the interior of the helmut and none were enclosed. This it turns out is an error on One K as they no longer enclose these additional pads but have not updated their packaging. The helmut is great and other than that little hurdle I'm glad to have this to take to shows!
Date published: 2015-04-06
Rated 5 out of 5 by from Love it! Was afraid it wouldn't fit. I bought this after taking a fall with my Charles Owen AYR8 and deciding to look for something a bit more ventilated. I was afraid the OneK wouldn't fit, since a lot of people say if the CO fits you then you must have a long oval head and this won't. I think if anything this helmet might fit me better! In comparison, the Pegasus helmets do NOT fit me, they are very round. I bought from SmartPak because I knew if it didn't fit, I would be able to return for free and get something that did. I have only ridden in it once in warm weather, so I can't really attest to how much better it is sweat-wise than the CO yet, but there is certainly more airflow. This helmet is super comfortable, and a great price. Between this and CO, I would go with this one, hands down.

Rated 5 out of 5 by from Love my One K Helmet I love my new One K helmet. I have an IRH but it has never fit right. This One K, fits perfectly and I love being able to replace the liner when it gets dirty!
Date published: 2015-02-27
Rated 5 out of 5 by from Love it 100%! I bought this helmet last year as an upgraded show helmet from my IRH. I stared showing all rated shows so it was a much needed upgrade. I tried it on and loved it!! Very very very comfy and very secure. It thankfully runs a tad large for us riders that ride in hairnets with all of our hair inside the helmet. It has recently become really popular at the rated shows in hunters, jumpers and equitation. Love it!
Date published: 2015-02-08
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.
Date published: 2015-02-05
Rated 5 out of 5 by from Great design and ventalization A perfect fitting and ascetically pleasing helmet! Love the comfort of the chin strap as well.
Date published: 2015-01-28
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 Excellent helmet This helmet was for our daughter who is very happy with it.
Date published: 2015-01-08
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.
