ROCKBROS Hard Shell Trunk Bag makes it a breeze to transport your cargo safely in any weather or terrain condition, thanks to its tough exterior and waterproof cover. With a large capacity, it can accommodate a significant load and is a versatile choice for holding anything from bike gear to snacks. You will also find it to be a stylish carrier for other travel purposes, as it comes with a shoulder strap for easy portability. It can easily be secured to the rear rack using the velcro straps.
Key Features:
Superior Quality and Waterproof Construction
This large trunk bag is designed using premium-quality materials to serve you for years to come. Its tough exterior is crafted from reinforced PU-coated polyester, guaranteeing high weather resistance and extreme durability. The zippers are also water-resistant to prevent moisture from seeping in. The extra waterproof cover will help you tackle situations of heavy rain and keep heading on your journey!
Large Capacity for More Storage
With a 9L max capacity and measuring 13.2” (L) x 7.9” (W) x 8.65” (H) in size, this trunk bag is spacious enough to store all your cycling essentials like bike tire pumps, cable lock, jacket, snacks, and many more. The main compartment features two interior mesh pockets to store your smaller items. This trunk bag is great for holding fragile items owing to its fixed structure and the hard protective layer. You can also use the elastic drawstring on top to attach or secure oversized items external to the bag.
Versatile in Purpose
Whether it’s running errands or heading on a camping trip, this hard shell bag will be a convenient utility for you. We think it will be particularly useful for those in need of a tough bag to carry their tools around. It’s also chic enough to accompany you on casual trips and can conveniently be handheld or carried as a shoulder bag.
Easy Attachment
You don’t need any tools to mount this rear rack bag. All you have to do is fasten the four velcro straps on the bag to the rack, securing it in place. It will remain very stable, no matter how rough the ride is! Disassembly is equally hassle-free. As the velcro straps are adjustable, the ROCKBROS Hard Shell Bike Trunk Bag fits effortlessly to most bike racks, such as mountain bikes, road bikes, e-bikes, hybrid bikes, and gravel bikes.
Improved Night Visibility
The reflective strips and the logo on the trunk bag improve visibility and enhance your safety during night rides. There’s also a hanger to hold a taillight, which will be particularly useful for riding in low-light conditions.
