We're bringing you this product at the lowest price allowed by the manufacturer. That means this item isn't eligible for additional 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'!).

Why We Love This

The One K Defender Matte Helmet is sure to keep you cool with two side, two front, one back, and two center stripe vents! This all-around stylish helmet is great for both schooling and showing in a number of different disciplines!

    One K Defender Matte Helmet is rated 4.7333 out of 5 by 30.
    Rated 5 out of 5 by from Love! This helmet is comfortable, looks good, and is on the inexpensive side. It seems like an affordable version of a Samshield. I love the removable liner. I haven't been able to test it in the heat yet, but it feels nice and light while still being substantial enough to save my head. :D My favorite thing about it, though, is that it looks as nice as a $400 helmet for half the price!

    Rated 5 out of 5 by from Great helmet at a great price! I needed a new helmet but I didn't want to pay $500 for one. I had tried on this helmet at a local tack shop and I loved it! I chose to buy my helmet through smartpak because they have wonderful customer service and a price that couldn't be beat! The helmet is a great fit though a little tight when my hair is up inside it. That's not a problem though because in due time I'm sure it will stretch just enough. I highly recommend this helmet for the rider on a budget!

    Rated 4 out of 5 by from Nice schooling hat Great quality helmet, good shape and nice added ventilation. Sizing is accurate. The chin strap has a lot of added pieces on it which take some getting used to, but overall they are not bothersome.

    Rated 5 out of 5 by from Great helmet I have had this helmet less than a month but have used it probably 20 times and I love it. It fits really well like it was made just for me, I didn't even have to adjust the straps! Very comfortable and well worth the price.

    Rated 5 out of 5 by from Great fit I love my new helmet! It is very comfortable, stylish and easy to care for. I like that the liner is removable for more stinky helmets. Haven't used it in the heat of summer, but look forward to the improved airflow.

    Rated 4 out of 5 by from great helmet! This helmet is super comfortable and the liner is awesome, it looks great AND at a reasonable price! The only con to it is the chin strap, and its only that it is a little stiff out of the box and sits a little bit forward on my chin, but other than that its super!

    Rated 5 out of 5 by from Great helmet! I just purchased this helmet a few weeks ago, and I love it! Beautiful quality. It is very lightweight which I really like. It seems very durable but I haven't had it long so I can't say for sure. I have an especially large head so it was important for me to have a low-profile design, and this helmet really has that which I appreciate. This helmet definitely runs small, be sure to size up if you are in between sizes.

    Ever since I was the girl with 1,000 breyer horses and the raggity braid in her hair, I was always obsessed. In second grade I moved into a town with a barn right down the street, which is when I started taking lessons...
