As riders and online shoppers, we know it can be tough to buy a new bridle or pair of boots without trying them on. That's why we moved the fitting room to your living room (or barn)! From breeches to blankets, if you or your horse can try it on, you can return it, free! Just request a return with a FREE SmartPak return label from your Order History within 60 days of the purchase date. And of course, please make sure the item is in like-new condition with original packaging (we said 'fitting room', not 'war room'!).

    One K Defender Avance Wide Brim Helmet is rated 4.0 out of 5 by 3.
    Rated 2 out of 5 by from Long oval is not long oval enough I bought this helmet for the wide brim and the fact that it was available in long oval. Unfortunately, it seemed far more round than oval on my head- VERY tight at the front and back, and a big gap on the sides. Sadly, I had to return it.

    Rated 5 out of 5 by from Love! I bought this as a second helmet for schooling. Let me tell you, it looks and fits just as well as my KASK. Very impressed with this product.

    Rated 5 out of 5 by from Very comfortable fit!! I bought this ito replace my old One K helmet that was over 5 years old. I decided to buy the oval shaped and was so happy I did. I didn't think it would make that much difference in the fit, but it definitely did. If possible, it fits even better than my old one! I love this helmet.
