Best hiking backpack overall
Maelstrom Maelstrom 40L Hiking Backpack, Lightweight Camping Daypack

Maelstrom 40L Hiking Backpack, Lightweight Camping Daypack

Brand: Maelstrom

Best for

Day hikers and weekend backpackers who want a 40-liter pack that covers both single-day trail use and short overnight trips in one pack, where Maelstrom's lightweight construction keeps pack weight down so the 40-liter capacity does not add excessive base weight over a smaller daypack.

Skip if

Multi-day backpacking with more than 2 nights of gear is planned. A 40-liter pack can accommodate 1 to 2 nights of ultralight gear but struggles with 3-plus night trips. For multi-day backpacking, a 50 to 65-liter pack provides the volume for a full sleeping bag, shelter and clothing for extended trail trips.

Brand: Maelstrom

Best for

Skip if

Dry climate hiking is the primary use. Waterproof pack materials are stiffer and slightly heavier than non-waterproof materials at the same volume. For desert Southwest or dry mountain hiking where precipitation is minimal, the standard Maelstrom 40L at $50 provides the same capacity at slightly lower weight.

Generic Lightweight Hydration Backpack, Running Backpack with 2L Water Bladder

Brand: Generic

Best for

Skip if

More than a day of hiking gear needs to be carried. A running hydration pack with a 2L bladder is a minimal-carry design for fast trail movement. For day hikes where trail snacks, extra clothing and camera gear are also carried, a standard 20 to 40-liter hiking daypack with a hydration sleeve provides the same water access with more gear capacity.

Questions people ask

How do I choose a hiking backpack size?

Choose hiking backpack size based on trip length and how much gear you carry. For half-day hikes with water, snacks and a rain layer, 15 to 20 liters is sufficient. For full-day hikes with lunch, extra layers, first aid and emergency gear, 25 to 35 liters handles the carry. For overnight hikes with a shelter, sleeping bag and cooking gear, 40 to 50 liters is the minimum for ultralight setups; 50 to 65 liters for standard gear. A backpack that is too small forces food and gear into outside pockets or attached externally, shifting the center of gravity away from the back and making the load unstable on uneven trail surfaces.

What features matter most in a hiking backpack?

Hip belt padding is the most important comfort feature in a hiking backpack because it transfers 60 to 80 percent of the pack's weight to the hips rather than the shoulders, which reduces shoulder fatigue on long hikes. Back panel ventilation prevents heat buildup between the pack and the back, which is a significant comfort factor on warm-weather and strenuous hikes. A hydration bladder sleeve with routing for the drinking hose keeps water accessible without stopping. External stretch pockets on the hip belt and shoulder straps provide fast access to frequently reached items like a phone, snacks or a rain layer without removing the pack. Load lifter straps at the top of the shoulder straps allow fine adjustment to pull the pack load closer to the back for better balance.

Should I buy a hiking backpack with or without a frame?

An internal frame hiking backpack uses aluminum stays or a plastic back panel to distribute load and transfer weight to the hip belt, providing better balance and hip loading than a frameless pack. Internal frame packs are preferred for loads over 20 pounds because the frame prevents the load from shifting away from the body's center of gravity. Frameless hiking packs are lighter and more flexible than internal frame designs, and are preferred by ultralight backpackers who keep total pack weight under 15 pounds. Frameless packs at heavier loads become unstable and painful because the soft sides allow the heavy load to pull away from the back. Most hiking daypacks do not have frames; most overnight and multi-day backpacking packs do.
