8 Best Ultralight Backpacks 2025 in the United States

The Loowoko 50L Hiking Backpack is a versatile and lightweight option designed for outdoor enthusiasts. Weighing only 2.1 pounds, it is easy to carry and suitable for 3-5 day trips. Its spacious 50-liter capacity is great for those needing ample room to store gear. The backpack is well-organized, featuring a large main compartment, a separate shoe section, and six external pockets. This makes it easier to distribute and access your items.

Additionally, it includes practical features such as compression straps and various attachment points for equipment like sleeping bags and trekking poles. A notable advantage is the included rain cover, providing extra protection against heavy rain and keeping contents dry. The backpack is constructed from tear-resistant polyester and nylon fabric, contributing to its durability and wear resistance. Comfort-wise, the backpack is designed with breathable mesh shoulder straps and sponge padding, helping to alleviate shoulder strain.

The widened and thickened S-type shoulder straps, combined with high elastic breathable back support, enhance ventilation and reduce burden. On the downside, the lack of an internal frame might affect the structure and support, potentially making it less suitable for carrying heavier loads. The absence of an internal frame could also limit its suitability for longer, more demanding treks. However, for most casual hikers and outdoor adventurers, the Loowoko 50L Hiking Backpack offers a balance of lightweight portability, capacity, and comfort.

The Granite Gear Blaze 60L Backpack is a strong contender in the ultralight-backpacks category, offering a good balance of weight, capacity, and comfort. Weighing in at a manageable level, it is designed to carry up to 50 pounds (22.7 kg) thanks to its A.C. (Air Current) Frame, making it suitable for longer hikes or multi-day trips. The dual-density shoulder harness with load-lifter straps enhances comfort, while the removable sternum strap and whistle buckle add an extra layer of safety.

The cinch-and-roll closure with crossing webbing straps ensures that your gear is secure and compressed, which is essential for maintaining balance and ease of use on the trail. One standout feature is the removable lid compartment, which can be converted to a chest pack, offering versatility in how you carry your gear and access essentials quickly. The hydration port and internal hydration sleeve are thoughtful additions for staying hydrated without needing to stop.

In terms of durability, the pack appears solid, though the need for hand washing might be a slight inconvenience for some users. On the downside, some users might find the capacity of 60 liters either too large or too small depending on their specific needs, and the various straps and compartments might seem overwhelming to those who prefer a simpler design. Despite these minor drawbacks, the Granite Gear Blaze 60L Backpack is a well-rounded choice for anyone seeking a versatile and durable ultralight backpack.

The Granite Gear Crown 3 60L Backpack is designed to cater to ultralight backpacking needs, offering an impressive balance of weight, capacity, comfort, and durability. Weighing only 1 pound, it stands out in the ultralight category, allowing you to carry necessary gear without adding much weight. With a spacious 60-liter capacity, it is well-suited for multi-day hikes, providing ample room for all your essentials.

The dual density shoulder harness, load-lifter straps, and dual removable sternum strap collectively ensure a comfortable carry, even when the pack is fully loaded. Additionally, the large hip belt pockets and roll-top main compartment make accessing and organizing your gear convenient. For hydration, it features a port and internal sleeve, a much-appreciated addition for long treks. The 3M reflective logo adds a layer of safety for visibility in low-light conditions.

However, while the backpack excels in many areas, it may not be the best fit for those who prefer more rigid frames, as it is designed to be flexible and lightweight. The polyester material, while durable, might not be as robust as some other higher-end materials used in heavy-duty backpacks. Also, with a price point that could be on the higher side for budget-conscious buyers, it caters more to serious hikers who prioritize ultralight gear. This backpack is particularly beneficial for avid hikers looking for a comfortable, lightweight, and spacious option that doesn't compromise on essential features.
