1. Thule Motion XT XL: Best Overall
In our evaluation, the Thule Motion XT XL stands out for its refined design and robust construction. It offers a spacious 16 cubic feet of storage while maintaining a low profile that complements the Crosstrek’s roof line. The dual-side opening is a practical touch, allowing access from either side of the vehicle. Owner feedback consistently praises its secure mounting system and minimal wind noise, even at highway speeds.
However, this roof box comes at a premium cost. If you are looking for a more budget-friendly option, this may not be the best choice. Also, its length may overhang slightly on the Crosstrek, so check clearance with the rear hatch open. We recommend it for those who prioritize quality and are willing to invest in a top-tier product.
- Dual-side opening for easy loading
- PowerClick quick-mount system with torque indicator
- Aerodynamic design reduces wind noise and drag
Pros: Excellent build quality and weather sealing; Sleek, low-profile look on Crosstrek
Cons: High price point, may not suit budget-conscious buyers
2. Yakima GrandTour 16: Best Aerodynamic
Based on owner feedback and the spec sheets, the Yakima GrandTour 16 excels in aerodynamic efficiency. Its swept-back shape is designed to minimize wind resistance, which can help maintain fuel economy on long trips. The interior LED light is a thoughtful addition for loading in the dark. Security is also strong with built-in locks that are easy to use.
That said, some owners report that the mounting hardware may not align perfectly with all crossbar styles, requiring extra adjustment. If you have aftermarket or non-standard crossbars, check compatibility carefully. This box is ideal for Crosstrek owners who frequently drive long distances and want to minimize fuel penalty.
- Swept-back design for improved fuel economy
- Tool-free SKS locking system included
- Interior LED lighting for low-light access
Pros: Excellent aerodynamics reduce drag; Integrated locks provide peace of mind
Cons: Mounting can be finicky on some crossbars
3. SportRack Vista XL: Best Value
We researched the SportRack Vista XL as a strong contender for budget-minded Crosstrek owners. It offers a respectable 15 cubic feet of storage at a fraction of the cost of premium brands. The universal mounting system is straightforward, and the gas strut-assisted rear opening is convenient. Owner reviews note that it holds up well over time, with minimal fading or cracking.
However, its max load of 110 pounds is lower than many competitors, so you cannot pack heavy items like camping gear or tools. If you frequently carry heavy loads, this may not be sufficient. Also, the finish is glossy, which can show scratches more easily. We recommend this box for light to medium cargo needs where budget is a priority.
- Gloss black finish with UV-resistant coating
- Universal mounting system fits most crossbars
- Rear opening with gas struts for easy access
Pros: Affordable without sacrificing essential features; Lightweight design easier to handle solo
Cons: Weight capacity lower than some premium boxes
4. Thule Pulse M: Best Compact
In our evaluation, the Thule Pulse M is an excellent choice for Crosstrek owners who need a smaller, more manageable box. Its compact dimensions make it easy to mount and remove, and it fits well without overhang. The SlideLock system is user-friendly, and the ability to mount it opening from either end adds flexibility. Owner feedback highlights its solid build and quiet operation.
But with only 11 cubic feet, it may not accommodate larger items like skis or multiple suitcases. If you often travel with bulky gear, this box will feel cramped. It is best suited for singles or couples with light luggage needs, or for daily use to store emergency gear and sports equipment.
- Compact size ideal for shorter roofs
- SlideLock mounting system with one-handed operation
- Can be mounted with rear opening or front opening
Pros: Perfect for Crosstrek with limited roof space; Easy to store when not in use
Cons: Small capacity may not suit families
5. Yakima SkyBox 16 Carbonite: Premium Pick
Based on our research, the Yakima SkyBox 16 Carbonite is a top-tier option for Crosstrek owners who demand durability and style. Its textured carbonite finish is highly resistant to scratches and UV damage, and the dual-side opening with gas struts makes loading effortless. The mounting system is robust and includes torque indicators to ensure proper installation. Owner reviews consistently rate it highly for long-term reliability.
However, this box is heavy, weighing around 50 pounds empty. Mounting it solo can be challenging, and it may require assistance. Additionally, the premium comes at a higher cost. If you are not concerned about weight and want a box that will last for years, this is a great choice. Those with physical limitations may want to consider a lighter alternative.
- Carbonite texture resists scratches and UV
- Dual-side opening with gas struts
- Tool-free mounting with integrated torque indicators
Pros: Premium finish and rugged durability; Excellent security with integrated locks
Cons: Heavy and may require two people to mount
6. Goplus 15 Cubic Feet Roof Cargo Box: Budget Pick
We researched the Goplus 15 Cubic Feet Roof Cargo Box as an entry-level option. It offers a generous 15 cubic feet of space at a low cost, making it accessible for those on a tight budget. The mounting hardware is basic but functional, and the lock provides basic security. Some owners report satisfactory performance for occasional use.
However, durability concerns are common. The plastic shell may crack under extreme temperatures, and the seal may allow water ingress in heavy rain. If you need a box for frequent long trips or harsh weather, we recommend investing in a higher-quality model. This box is best for occasional use and mild climates, where cost is the primary factor.
- Affordable price with basic features
- Universal mounting brackets included
- Lockable with two keys
Pros: Very budget-friendly; Decent storage space for the price
Cons: Build quality and weather sealing are average
7. Rhino-Rack MasterFit 15S: Best Fit
In our evaluation, the Rhino-Rack MasterFit 15S stands out for its versatile fitment. It is designed to work with most factory and aftermarket crossbars, including the Crosstrek’s standard setup. The dual-side opening is convenient, and the gas struts hold the lid open securely. Owner feedback highlights its sturdy construction and good weather resistance.
However, some users find the installation instructions confusing, leading to initial setup frustration. Also, the textured finish, while durable, can be difficult to clean. If you have non-standard crossbars or want a box that fits without adapters, this is a solid choice. But if you prefer a simpler installation process, you might look elsewhere.
- Designed to fit a wide range of crossbars
- Dual-side opening with gas struts
- Textured finish for scratch resistance
Pros: Excellent crossbar compatibility; Good weight capacity for its size
Cons: Installation instructions could be clearer
Frequently Asked Questions
What size roof box fits a Subaru Crosstrek?
Most roof boxes between 11 and 16 cubic feet fit the Crosstrek well. We recommend measuring your roof length and checking rear hatch clearance. Boxes around 77 to 84 inches long typically work without overhang, but always verify with your specific model year.
Will a roof box affect my Crosstrek's fuel economy?
Yes, any roof box increases wind resistance and can reduce fuel economy by 10-25% at highway speeds. Aerodynamic models like the Yakima GrandTour 16 minimize this effect. We advise removing the box when not in use for best efficiency.
Can I open the rear hatch with a roof box installed?
It depends on the box length and mounting position. Shorter boxes (under 70 inches) usually allow full hatch opening. Longer boxes may require sliding the box forward or tilting the hatch partially. We recommend checking your vehicle’s specifications and the box’s dimensions before purchase.
What is the weight limit for a Crosstrek roof box?
The Crosstrek’s roof load capacity is typically 150-165 lbs including the crossbars and box. Most roof boxes have a max load of 110-165 lbs. We advise staying within the combined limit to avoid roof damage and ensure safety.
Do I need special crossbars for a roof box?
Most roof boxes come with universal mounting hardware that fits standard crossbars. The Crosstrek’s factory crossbars work with many boxes, but aftermarket crossbars may require adapters. We recommend checking the box’s compatibility list before buying.
Our Verdict
After researching and comparing the top options, our top pick is the Thule Motion XT XL for its outstanding build quality, ease of use, and aerodynamic design. For a more budget-friendly choice that still delivers solid performance, the SportRack Vista XL is our runner-up. Both are excellent additions to your Subaru Crosstrek for extra cargo capacity on your adventures.
