10 Best Cycling Backpacks 2025 in the United States

The CamelBak Hydrobak Light is a well-designed hydration backpack tailored for cyclists who need a lightweight, comfortable option for shorter rides. Its 1.5-liter reservoir offers enough water for moderate trips without weighing you down, making it ideal for training or outdoor activities. The backpack uses breathable materials with the Air Support Light back panel and ventilated harness, helping keep your back cool during rides, which enhances comfort.

Its adjustable straps allow a snug fit, but riders with larger frames might find the capacity and size a bit limited. Storage is modest but practical, featuring a secure zippered pocket perfect for essentials like keys or your phone, plus a handy helmet carry for convenience. While it doesn't focus on heavy weather resistance, its lightweight and durable materials can handle some light moisture but may not be suited for very wet or harsh weather conditions.

Reflective elements are not a prominent feature, so visibility in low light might require additional accessories. If you are looking for a simple, reliable hydration pack to keep you hydrated and comfortable without extra bulk, this CamelBak option serves well, especially for casual or fitness cycling rather than long-distance touring.

The Everfun Hydration Backpack 18L is a versatile and practical choice for cyclists, hikers, runners, and outdoor enthusiasts. With an 18-liter capacity, it offers ample space for essentials like clothes, first-aid kits, and personal valuables. The backpack is designed with 9 functional divider pockets, including a specific area for trekking poles or water bottles, making organization straightforward and efficient. Its separate insulated compartment for the 2-liter water bladder can keep liquids cool for up to 6 hours, which is great for longer activities.

The upgraded hydration system with a high-flow bite valve and food-grade material ensures easy and safe drinking on the go. However, users needing more capacity might find the 18-liter size limiting for extended trips or carrying bulkier items. The backpack is made from durable high-density nylon fabric, which, combined with the built-in rain cover, provides excellent weather resistance. Reflective strips enhance visibility in low-light conditions, adding an extra layer of safety.

Comfort is also a priority, with a lightweight design at 1.7 pounds, adjustable chest and waist straps, and breathable padding for extended wear. While the ventilation system is satisfactory, some users in extremely hot climates might wish for more advanced airflow features. The unisex design and sleek black color ensure it appeals to a broad audience. The Everfun Hydration Backpack is a solid option for anyone needing a multi-functional, reliable hydration pack for various outdoor activities.

The Thule Aion Travel Backpack 40L offers a significant capacity of 40 liters, providing ample space for carrying essentials during long cycling trips.

It includes a removable TPU rolltop bag for additional storage, which can be tucked away when not in use, enhancing its versatility. The padded storage for electronic devices such as laptops and tablets adds an extra layer of protection. Fit and comfort could be enhanced with the addition of the Thule Aion Sling Bag, which doubles as a supportive hipbelt, though this is sold separately.

The zippered top pocket and various compartments offer excellent storage and organization, keeping small items secure and accessible. Cyclists looking for a durable, weather-resistant backpack with substantial storage and organizational features may find the Thule Aion Travel Backpack beneficial.
