If you want a rugged, versatile cargo box with a proven mounting system for any bar type and slightly less bulk on the roof, choose INNO Wedge Plus BRM865; if you need maximum interior volume for van life gear and a sleek, modern aesthetic that fits specific crossbars, choose Yakima SkyBox NX 16.
• INNO Wedge Plus BRM865: Offers 13 cu ft of space with a universal fit for aero, square, and round bars, making it ideal for those with older or varied rack setups who value durability over sheer capacity.
• Yakima SkyBox NX 16: Delivers a spacious 16 cu ft with a flattened floor design optimized for irregular shapes, perfect for van lifers needing every inch of room but restricted to StreamLine-style crossbars.
• Who each pick is for: The INNO suits adventurers with diverse vehicle setups who prioritize a tight aerodynamic profile, while the Yakima is the choice for travelers prioritizing raw storage volume and a low-profile look on compatible vehicles.
The INNO Wedge Plus BRM865 is built for the practical traveler who needs reliability without fuss. With 13 cubic feet of storage, it strikes a balance between holding significant gear and maintaining a lower center of gravity on your roof. This is not a massive hauler, but it is a highly efficient one. The exterior dimensions of 80.75 by 33 by 13.5 inches give it a distinct wedge shape that cuts through wind resistance better than boxier alternatives. If you are driving a vehicle where height clearance is a concern, this unit sits lower to the roofline than many competitors in its class.
What really sets this unit apart is its mounting flexibility. It utilizes the INNO Universal Mounting System, which means it does not care what kind of crossbars you have. Whether you run factory-installed bars, round tubes, square profiles, or modern aero bars, this box adapts. This versatility is crucial for owners who might swap vehicles or use different racks for different trips. The construction itself feels substantial, using a three-layer ABS top material combined with SPM injection for the base. This isn't just plastic; it is engineered to withstand the rigors of road travel without cracking under stress.
You should buy this if you need a secure, lockable solution that works with almost any car rack configuration. The dual-side opening allows you to load skis or snowboards from either the driver or passenger side, which is a lifesaver when parking in tight spots. However, you should skip this if your primary goal is transporting oversized camping equipment like large coolers or bulky sleeping bags that require more than 13 cubic feet of space. The interior dimensions of 72 by 25.5 by 11 inches are generous for sports gear, but they will feel cramped for extended van life setups requiring heavy storage.

The Yakima SkyBox NX 16 is designed for the person who refuses to compromise on space. With a generous 16 cubic feet of capacity, it immediately outclasses the INNO in terms of raw volume. This extra three cubic feet is not trivial; it translates to real-world utility for van lifers or families who need to pack multiple campers, large dry bags, or long items that exceed standard lengths. The internal usable space features an unobstructed flattened floor, a design choice that significantly improves how you can arrange your gear. Unlike boxes with curved bottoms that waste corner space, this flat floor lets you stack items efficiently and utilize the entire footprint.
This box is also about aesthetics and ease of use. The NX nano-texture on both the lid and base gives it a clean, sleek look that blends well with modern vehicle designs. The full metal opening handle is a tactile upgrade over plastic levers, offering a robust feel that inspires confidence in security. The locking mechanism secures both the gear inside and the box to the vehicle, ensuring your belongings stay put during transit. However, this premium comes with a constraint: it is specifically designed to fit StreamLine crossbars. If your vehicle has round, square, or non-compatible bars, this box simply will not work without an adapter kit that may not be listed in the standard specifications.
You should choose the Yakima if you own a vehicle equipped with StreamLine crossbars and you need to maximize every inch of storage for long-term travel. The dual-sided access is equally convenient here, allowing you to load from whichever side of the vehicle offers the best access. But you must skip this model if your roof rack setup is generic or older style. Without the specific compatibility, the superior volume becomes useless. It is a specialized tool for those who know exactly what their rack looks like and need the extra room to make their journey comfortable.

In my opinion, if I were preparing for a van life adventure where every foot of space counts, I would choose the Yakima SkyBox NX 16. The extra three cubic feet and the flattened floor make a tangible difference when you are living out of your vehicle and need to store large, irregular items. However, if I did not own a StreamLine rack, I would immediately switch to the INNO Wedge Plus BRM865 because its universal mounting capability saves me from buying expensive new bars. For the average buyer looking for a reliable, versatile solution that fits most cars, the INNO is the safer, more flexible bet. Ultimately, the choice depends entirely on your roof rack hardware and your specific volume needs.
