9 Best Mountain Biking Backpacks 2025 in the United States

The CamelBak H.A.W.G. Pro 20 Bike Hydration Backpack is designed for mountain biking enthusiasts who need a reliable and comfortable pack for long rides. It features a substantial hydration system with a 100-ounce (3 liters) water reservoir, which is excellent for keeping hydrated on extended rides. The body mapping technology used in the Air Support Pro Back Panel ensures good ventilation and comfort, helping to prevent overheating by targeting heat-generating areas. Additionally, the 3D Vent Mesh Harness enhances comfort and breathability, making it suitable for all-day use.

The hip belt with cargo pockets provides stability and easy access to essentials without needing to stop and unpack, and the integrated tool roll keeps tools organized and secure, which is a great addition for those who like to be prepared for any mechanical issues on the trail. The helmet carry feature is also beneficial for securing your helmet when not in use. However, at 2.7 pounds, some users might find it slightly heavy, especially when fully loaded. With a capacity of 6 liters, the backpack provides adequate space for essentials but might be limiting for those needing to pack extra gear.

CamelBak is a reputable brand known for high-quality products, and this backpack comes with a 'Got Your Bak' lifetime guarantee, offering peace of mind. The item’s dimensions suggest it is compact enough not to be cumbersome, yet spacious enough for necessary items. This backpack is best suited for serious cyclists and outdoor enthusiasts who prioritize hydration, comfort, and organization on their adventures.

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.
