We're bringing you this product at the lowest price allowed by the manufacturer so you won't find it cheaper anywhere else. This also means we can't apply any further discounts or promotions.

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 use the pre-paid return label included in your order within 60 days from 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 Suede Helmet is rated 4.863013698630137 out of 5 by 73.
Rated 5 out of 5 by from Perfect helmet Fits perfect, super lightweight and extremely comfortable with great air flow, and being able to wash the lining is a HUGE plus! I bought it as a schooling helmet but it looks so good I'm using it for shows. I have been getting compliments on this helmet from everyone!

Rated 5 out of 5 by from Very comfy I bought this helmet 2-3 weeks ago and it is the most comfy thing I've put on my head, it fits well, it shapes to my head, and to add it has great ventilation. Hope this helped if you are looking to buy this helmet. I totally recommend this product

Rated 4 out of 5 by from Didn't fit - sent back I really liked this helmet a lot but I immediately sent it back as soon as it arrived. It didn't fit my head at all. I currently have a Charles Owen AYR8 in 7 3/8." I purchased an XL OneK and it did not fit whatsoever. No fault of One K just was WAY too round for my rather oval head. Planning to order a OneK in Long Oval when I get around to it.

Rated 5 out of 5 by from Perfect fit! I had to get a helmet with a removable liner because of the hot, humid summers here in Ohio so I chose this one. Initially, it felt snug and "almost" too tight but never hurt, pinched or caused a headache like previous helmets I've had. Also, this one is by far the most comfortable and squishy! My last helmet cost $150 more than this one and never fit this well. Will buy again definitely!
