If you want a versatile, weather-resistant solution for carrying long watercraft like kayaks or surfboards on your roof during those rugged hunting trips, choose HEYTRIP Universal Soft Roof; if you need a heavy-duty, tool-free carrier specifically designed to transport bicycles on the rear of your vehicle, choose GRIRIW Bike Trunk Mounted. These two products serve fundamentally different purposes, and confusing their capabilities is a recipe for frustration or even danger on the road. I have analyzed the specifications and design intent behind each system to help you decide which one belongs in your garage before you head out into the field.
• This pick is for hunters and adventurers who need to haul bulky, elongated gear like kayaks or canoes across varied terrain.
• This pick is for cyclists and outdoor enthusiasts who prioritize stability and capacity for multiple bikes over roof mounting options.
The HEYTRIP Universal Soft Roof is engineered for a very specific scenario: moving long, awkward loads over the top of a vehicle that lacks a permanent factory rack. If you are planning a hunting trip where you need to transport a kayak loaded with game or simply carry your canoe to a remote lake access point, this soft rack system is built to handle the job without requiring expensive modifications to your car. The design relies on a flexible, padded structure rather than rigid bars, making it ideal for vehicles with smooth roofs, side rails, or gutters. You do not need to be an expert mechanic to install it; the system comes with all necessary attachments and straps, meaning you can get it mounted quickly before you hit the trail.
What stands out most about this product is its focus on protecting both your cargo and your vehicle. The inclusion of top-grade EVA foam padding provides a soft landing for your boards or boats, effectively reducing vibration while driving over rough roads often found near hunting grounds. Furthermore, the non-slip matting prevents scratches on your car's finish, a critical feature if you frequently move between paved roads and muddy trails. The package includes four ultra-long 15-foot straps—two for securing the load to the roof and two for bow and stern tie-downs—which ensures that even long items remain stable against wind forces. This level of security allows you to carry up to three shortboards or two longboards, giving you significant flexibility for group trips or solo expeditions.
However, this system demands attention to detail regarding installation. While it is "no tools required," achieving a quiet ride requires you to twist the straps correctly to minimize wind noise, a technique mentioned in the instructions but one that takes practice to master. If you are looking for a set-and-forget solution that requires zero adjustment, you might find the manual tensioning of these straps tedious. Additionally, because it is a soft pad system, it does not offer the same aerodynamic efficiency as a hard rack, which means you may notice slightly more drag at highway speeds. It is best suited for drivers who value versatility and portability over sleek aerodynamics, particularly those who use their vehicle for seasonal activities like paddling or hauling large hunting equipment.

The GRIRIW Bike Trunk Mounted rack is a dedicated solution for anyone whose primary goal is transporting bicycles on the rear of a sedan, hatchback, minivan, or SUV. Unlike the roof system, this unit is constructed from a durable black steel frame, providing a rigid structure that separates and firmly holds bikes in place. If you are heading out on a road trip with friends to hunt in areas accessible by bike, or if you simply need to commute with your mountain bike to a trailhead, this carrier offers a stable platform that keeps your wheels off the ground and away from road debris. The steel construction suggests a high tolerance for the vibrations and bumps encountered on unpaved roads leading to hunting spots or campgrounds.
One of the most practical features of the GRIRIW rack is its storage capability. When you are not using it, the entire unit folds into a compact shape that fits easily into the boot of most cars. This is a massive advantage for hunters who need to clear space in their vehicle for gear, coolers, or game bags once they have unloaded their bikes. The dimensions of 65x52x39 cm indicate a substantial footprint when unfolded, ensuring it can accommodate various bike sizes, yet it shrinks down significantly for storage. The design also emphasizes ease of use, stating that no tools are needed for setup, allowing you to mount it quickly on the trunk lid using the provided straps.
This added mass means you will feel the difference when lifting it in and out of your vehicle, especially if you are doing so alone after a long day of hiking. The reliance on trunk mounting also limits its application; it is strictly for the rear of the vehicle and cannot be used on the roof or hitch. Furthermore, the separation mechanism for holding bikes is key—if you are carrying very wide or uniquely shaped frames, you must ensure the cradles align correctly. It is the superior choice for those who prioritize a sturdy, steel-built carrier that can withstand the rigors of backcountry travel without worrying about roof clearance issues or wind lift.
• Best for long, narrow watercraft (kayaks/canoes): HEYTRIP Universal Soft Roof is the only logical choice here, as its length and padding are designed for these specific shapes.
• Best for transporting bicycles: GRIRIW Bike Trunk Mounted is purpose-built for bike frames and wheels, offering secure separation that roof pads cannot provide.
• Best for vehicles without roof rails: HEYTRIP Universal Soft Roof excels here, as it adapts to almost any vehicle type regardless of existing fixtures.
• Best for storage in the trunk: GRIRIW Bike Trunk Mounted wins for compact folding, keeping your interior cargo space free when the rack is stowed.
• Best for reducing wind noise on the roof: HEYTRIP Universal Soft Roof offers padded protection and strap-tensioning techniques to minimize aerodynamic whistling.
• Best for heavy-duty durability: GRIRIW Bike Trunk Mounted uses a steel frame, suggesting higher structural integrity for repeated loading of heavy bikes.
• Best for group hunting trips with mixed gear: HEYTRIP allows for carrying multiple boards or a single large boat, whereas GRIRIW is limited to bicycle capacity.
In my opinion, the HEYTRIP Universal Soft Roof is the more adaptable tool for a general hunter who needs to transport a variety of oversized gear, including kayaks or canoes, to remote locations. Its ability to fit any vehicle and protect delicate surfaces makes it a smarter investment for someone who prioritizes versatility over specialized function. However, if your primary mission involves riding bikes to the trailhead, the GRIRIW Bike Trunk Mounted is the undeniable winner due to its robust steel construction and dedicated bike-holding design. For the specific context of a hunting trip where you might need to carry a boat, I would choose the HEYTRIP system because it solves the problem of getting bulky, awkward loads onto the roof safely without needing a permanent rack.
The product information specifies compatibility with sedans, hatchbacks, minivans, and SUVs, implying it is designed for vehicles with a solid trunk lid or hatchback surface.
No, both products explicitly state that no tools are required for installation, relying instead on straps and adjustable fittings for setup.
When not in use, the GRIRIW rack folds into a small space that stores in the boot of most cars, with a folded profile around 39x52x65 cm.
