    Bad fit, nice helmetReview by Dudley
    Small is too small, medium is too big. And the liners don't work as advertised (I wasn't sure how they could). And a little annoyed that I have to buy another item to get the helmet to fit. I'll have to add extra padding myself to make sure it fits. That said, I love the look of the helmet. (Posted on 10/2/2016)
    Small head, perfect fitReview by flygirl
    I always have trouble finding hats and helmets to fit my head. If I can find them small enough to fit around, they are too big from ear, over the top of head to ear and a I have to tuck my ears in, which obviously starts to hurt after awhile. The One K in XS is the ONLY helmet I've found that fits my small head in every way. Super comfy! (Posted on 12/7/2015)
    Most Flattering ever!Review by Denise from Virginia
    This helmet has some shape to it that is very flattering for your face. Saw them at Devon, but they were out of my size. Thanks Adams for having it!
    I bought an extra liner and it is like having a new helmet all of the time. many compliments from my DQ barnmates too!

    Style Function and Fit!!!Review by Bailey from Tulsa, OK
    I love helmets, and this is one of my favorites, for once I dont feel like a helmet is going to slip around on my odd shaped head! plus its flattering and stylish but still subtle enough to wear in dressage tests, but doesnt get to hot! Love my Navy Helmet!

    Will never go back!Review by Keyanna from SC
    I used to be an avid IRH girl. I rode in one for YEARS, but recently bought they're new model and it gave me awful headaches. Tried multiple CO's too, no luck. I've got a rounder head and heard from friends that the One K would fit great. I tried it and LOVED it the first ride! I rode in it on a 100* day and barely knew I had anything on my head. It's easy to clean, super comfortable and a classy look. I'll be buying another to keep for just shows. I'll never go back to other brands! (Posted on 8/25/2015)
    Fantastic for round heads!Review by Kelsey from Canada
    I have been wearing helmets ever since I started riding (25 years ago or so.) The technology has come a long way in those 25 years. The One K Defender is no exception!
    I have a naturally round shaped head, and in the past have found that other helmet brands just made my head look huge! They were simply unflattering. The One K Defender is sleek, stylish and unbelievably flattering to those who have round heads, and fear that mushroom head look.
    This helmet is extremely comfortable, the harness is sleek and elegant, and the smaller details are excellent. The interchangeable liners are a nice perk, which I plan to take full advantage of. I live in a cooler climate, and cannot speak to breathability in a hot or humid climate, but so far so good up north.

    Great helmetReview by DragonTea from Aiken
    I was hesitant to try this since I'm an Owen's girl but I love to use this as my dressage helmet in my three day events.

    It's very flattering and lightweight. I get a lot of compliments on it. (Posted on 8/25/2015)
    Awesome!Review by Eventer76
    This is my new favorite! Love my Charles Owens but One K is just as comfortable and stylish at a very reasonable price. Can't get any better than that! (Posted on 8/15/2015)
