Why We Love This

The One K Defender Helmet liner is a smart purchase for the One K rider! Purchase an additional liner so you can have a spare when one needs to be thrown in the washing machine. These helmet liners are also great to help adjust the fit!

Imported.

Favorite Features

  • Provides the ultimate flexibility for growing children, shared helmets, or women who wear hair differently for schooling and show
  • Buy a liner that is either smaller or larger than your One K Helmet shell to adjust the fit
  • Machine washable

At SmartPak, your happiness is at the core of everything we do. We back every order with our 100% Happiness Guarantee so that you can shop with confidence. If you're ever less than thrilled with your purchase, just let us know and we'll refund you right away. No hassles, no hoops, no kidding.
Hassle-Free Returns

SmartPak Returns

We put our products to the test in our barns and on our horses, so we're confident that you'll be thrilled with your purchase. However, we know that life in the barn can sometimes be unpredictable. That's why we've created a stress-free return policy. If you purchase an item and it doesn't meet your expectations, we want to know about it, take care of you and give you your money back.

Free Return Shipping on all Sized Items

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'!).

The Fine Print

We love our products and we're happy to take them back - even custom items. We'll happily take back everything from engraved halters to personalized jackets - even embroidered blankets that have been worn (minus the manure, please). But there are a few things we have to restrict returns on (silly federal regulations).

Undergarments
Health regulations require that undergarments (including bras) need to be in new condition (tags and packages intact) in order to be returned. (Even if it wasn't required, do you really want to shop from a store that takes back used undergarments?!)

Saddles
As riders, we know what a big investment a saddle is. That's why we're proud to offer the best Test Ride program in the business. You can keep our Test Ride saddles risk-free for five days, to really make sure you like the fit and the feel. We know that to truly try a saddle, you have to really ride in it. So go ahead and girth it up. Forget about wrapping your stirrup leathers. Try it with or without a saddle pad. Basically, treat it like you already bought it, so you can make sure you really want to. Because when you buy a saddle from us, we want to make sure you love it. Of course, we want our other customers to love their new saddles, too.
That's why we have a Test Ride option for each saddle we carry - so that all of the other saddles can stay in pristine condition, waiting for their new owners. For this reason, if you purchase a saddle outside the Test Ride program, it's still eligible for return, but must be free from any marks or damage.

So that's it. Seriously. Those are all of our "rules." Well, except the most important one - treating our customers the way we want to be treated. So if you have any questions or if there is anything we can do, please call us at 1-800-461-8898 or email CustomerCare@SmartPak.com. We are always happy to help.

    One K Defender Helmet Liner is rated 4.8 out of 5 by 5.
    Rated 5 out of 5 by from Perfect replacement! I bought this so I could wash my original liner and not loose out on a few days of riding. LOVE how fast it was delivered (ordered on Wednesday night after dinner and it was on my doorstep when I got home from work 2 days later on Friday)!
    Date published: 2018-10-13
    Rated 5 out of 5 by from fits great, washes great I bought a replacement liner as the one that came with my One K helmet was pretty gross from summer sweat/makeup. I swapped this out in seconds, took the old one home and threw it in the wash and its as good as new. happy to have a fresh one on hand when i need to swap them out.
    Date published: 2018-08-29
    Rated 5 out of 5 by from Love the removable liner I love the removable liner on the One K helmets. Our summers are very humid, so I purchased a second liner to always have a clean/dry one ready for the next ride. I'm planning to buy one the next size up for winter so I have room for my thin fleece headband. Very happy with the liners and the helmet.
    Date published: 2016-07-27
    Rated 4 out of 5 by from Amazing Quality I bought this to put in my OneK helmet I bought the XL size and It was a little too big for my head so I ordered this liner in the size large so I wouldn't have to put my hair in my helmet every time I rode. It works amazingly and is super easy to put it in the helmet and to take it out of the helmet.
    Date published: 2016-06-06
    Rated 5 out of 5 by from easy to wash!! I bought this extra liner so I would always have a "fresh" helmet. It's so easy to wash, I throw it in my washer and let it dry on my porch. It dries in no time and my helmet no longer smells! Great investment. I love it.
