FAST & FREE SHIPING to the lower 48 states

We don't mess around with fine print and extra charges. Instead, we like things to be simple and easy for you. 

Read more about the terms and conditions that apply in our Shipping Policy

30-Day Easy Returns

As experienced Overlanders, we fully understand that things do not always go according to plan. 

That is why we offer you our "No Questions Asked" 30-Day Return Policy, so you can get back on the road for more adventures in a heartbeat.

We get it. You've got a lot of choices when it comes to online retailers, so why should you even bother spending your hard-earned bucks shopping with us? 

Here are four short reasons why Open Road Overland is not like the rest of the bunch and why we believe that your shopping experience with us is not only 100% safe, but will also exceed your expectations, so you come back for more and maybe even bring your friends.

REASON #1: 100% SAFE & SECURE ONLINE SHOPPING

We use encrypted SSL security and are Level 1 PCI DSS compliant to ensure that your credit card information and every transaction on our website are 100% protected. 

REASON #2: DRIVING THE WORLD SINCE 1998

We started overlanding in 1998, way before overlanding was even a term. Since then we have spent the last 25 years zig-zagging the planet trail testing the types of equipment you find in our store. In other words, we learned the hard way what works and what doesn’t, through hands-on experience during our own adventures on 6 continents (yes, we still haven’t made it to Antarctica). To ensure that we add value to your adventure with the products you shop with us, our policy is that nothing goes on our website before it has been thoroughly reviewed. This means that you will not find anything in our store that we would not bring along our use on our own overland adventures.

REASON #3: WE HAVE DRIVEN ALMOST EVERYTHING

Secondly, we have been driving almost any type of vehicle you can think of over the years. This means that we have acquired a strong skill set to answer any question you have concerning your own vehicle setup, no matter whether you drive a standard passenger car, a pickup truck, or a fully rigged 4x4 overlanding vehicle. 

REASON #4: WE WANT EVERYBODY TO GO OVERLANDING

Thirdly, we strongly believe and promote that overlanding should be accessible to everybody, no matter what you drive, or what level of experience you have. That means that we can guide you as a novice overlander just starting out, as well as giving advice to you as an ultra pro with years of bushwhacking behind the wheel. That’s why you will also see both entry-level products, as well as top-of-the-line gear on our site, so we can cater to everybody looking to elevate their own overland adventures. No matter what, you can rest assured that the products you find in our store are here because they do the job they were made to do. 

WHAT ELSE DO I GET?

Apart from the above we of course also provide you with:  

  • Free Shipping to the lower 48 states, with no extra charges. Ever!
  • Price Match Guarantee. Best prices online, guaranteed.
  • 30-Day Easy Returns. Not happy with your product, we'll take it back no questions asked, and without charging you ANY restocking fee. Ever!
