9 Best Mountain Biking Backpacks 2025 in the United States

The CamelBak M.U.L.E. 12 Mountain Biking Hydration Pack is a solid choice for mountain biking enthusiasts. Its 100oz (3 liters) hydration system is ample for long rides, and the magnetic tube trap ensures easy access to water without fumbling. The hydration pack includes a 9-liter capacity for other essentials, which is enough for tools, snacks, and a light jacket.

Fit and comfort are prioritized with the Air Support Back Panel and 3D Vent Mesh Harness, which provide excellent ventilation and all-day wearability. The removable waist strap adds extra stability, which is particularly useful on rough terrain. The pack's weight is reasonable at 810 grams, not too heavy for a comfortable ride. Durability is implicit with CamelBak's reputation and their 'Got Your Bak Lifetime Guarantee,' suggesting a long-lasting build.

The pack also includes 12 pockets for organization, making it easy to keep gear accessible and secure. The helmet carry feature is a thoughtful addition for those who want to store their helmet when not in use. The main drawbacks are the relatively small overall capacity (9 liters) for bulkier items and the higher price point, which might not be justified for casual riders. However, for serious mountain bikers, the features and reliability might be worth the investment.

The EVERFUN Hydration Backpack 18L is a versatile and spacious pack designed for mountain biking and other outdoor activities. With an impressive 18-liter capacity, it offers ample space for clothes, a first-aid kit, and other essentials. The nine functional divider pockets ensure that everything stays organized, including a built-in mesh pocket for valuables and special compartments for glasses and cameras. The external mesh pockets are convenient for carrying water bottles or trekking poles.

One standout feature is the insulated bladder compartment, which keeps liquids cool for up to 6 hours, making it ideal for long rides or hikes. It includes a 2-liter food-grade PEVA bladder with a high-flow bite valve, and supports up to a 3-liter bladder, catering to varying hydration needs. The backpack's high-density nylon fabric and built-in rain cover enhance durability and weather resistance, while reflective strips improve visibility in low-light conditions. Comfort is another strong point, thanks to the breathable padded back, and adjustable chest and waist straps, ensuring a stable fit for all body sizes.

At 1.7 pounds, it is lightweight enough for extended use without causing fatigue. However, its numerous pockets and compartments might make it seem bulky to some users, and the 2-liter bladder might not suffice for extremely long rides. Additionally, while the rain cover is a useful feature, its effectiveness in heavy rain remains to be tested. This hydration backpack is a solid choice for mountain bikers seeking a durable, comfortable, and well-organized pack.

The Osprey Raptor 14L Men's Biking Backpack offers a range of features tailored for mountain biking enthusiasts. It includes a 2.5L Hydraulics reservoir with easy access and a magnetic bite valve, making hydration convenient without interrupting your ride. The bike-specific winged shoulder harness and air mesh wrap hipbelt are designed to offer excellent stability, even on rough terrain, ensuring a comfortable fit for various body types, particularly those with broader frames.

The backpack excels in organization and accessibility, featuring hipbelt pockets, a LidLock helmet attachment, and an included tool roll, making it easy to carry and access essential items on the go. Additionally, the scratch-free zippered pocket is a thoughtful touch for protecting sunglasses and electronics. In terms of durability, the nylon material is robust, suitable for the wear and tear of mountain biking.

Weighing 2.15 pounds, the backpack is reasonable for its size and features, though some may find it slightly heavier compared to more minimalist options. Its capacity is adequate for day-long excursions but might be limiting for those requiring more storage space. Despite its higher price point, this backpack is a solid choice for mountain bikers who prioritize stability, organization, and comfort in their gear.
