10 Best Subaru Car Top Carriers 2026 in the United States

The Thule Force 3 L US rooftop cargo box is a solid choice for Subaru owners or anyone needing extra storage space on their vehicle. With a roomy 16 cubic feet capacity, it offers ample space for luggage, sports gear, or camping equipment. Its dimensions (80" long, 18" wide, and 38" high) are designed to fit well on most vehicles without being too bulky. Made from durable plastic, the box is built to handle daily use and resist weather, being water-resistant to protect your items inside.

The mounting system is particularly user-friendly, featuring a quick and secure mechanism that lets you know with a click when the box is safely attached, which is great for peace of mind on the road. Convenience is enhanced by access from both sides, so loading and unloading is easier no matter the parking situation. The box’s aerodynamic design helps reduce wind noise and drag, which can improve fuel efficiency compared to less streamlined carriers.

Security is addressed with the SlideLock system, which automatically locks the lid and clearly indicates when it’s securely closed, helping keep your belongings safe. Although the product does not specify an exact weight capacity, Thule’s reputation suggests it can handle typical cargo loads safely. Some users might find the size somewhat large if they only need minimal extra space, and the plastic shell, while tough, may not have the premium feel of higher-end materials. The Thule Force 3 L successfully balances durability, ease of use, and security, making it a dependable option for active lifestyles and everyday adventures.

The Thule Motion 3 XL is a well-designed roof cargo box that offers 18 cubic feet of storage space, making it a solid choice for Subaru owners who need extra room for gear on trips. Its wing-shaped, forward-leaning nose helps reduce wind drag, which can improve your fuel efficiency compared to less aerodynamic carriers. Made from lightweight aluminum, it weighs just 8 pounds, so it won't add too much extra weight to your vehicle. Mounting the box is straightforward thanks to the PowerClick quick-mount system, which signals when the box is securely attached, saving you time and effort.

The SlideLock system keeps your belongings safe by automatically locking the lid and letting you know when it’s closed properly. The box is designed with convenience in mind, featuring a sturdy lid and a wide handle that allows smooth one-handed opening and closing. While it offers several useful accessories like an interior light and protective liner, one downside is that it is not water-resistant, so it may not fully protect your items in heavy rain or extreme weather. Also, the narrow width (18 inches) means it might not fit larger items as easily as wider models.

This rooftop carrier represents a great option for Subaru drivers looking for a secure, easy-to-use, and aerodynamic box for their outdoor or travel needs, especially if you prioritize quick setup and good locking features.
