Detailed Reviews
1The Maelstrom 40L is the budget hiking pack we point most first-timers toward. The shell is 210D ripstop nylon, and a rain cover lives in a small pocket under the base, so a surprise shower does not end the day.
It is a frameless daypack-style design, so it carries best below about 20 pounds. Within that range, the padded straps, chest strap and simple hip strap keep it steady on a day hike, a hut trip or a weekend in a city where you walk a lot. Owners mostly praise the pocket count and the value; the main complaint is that the thin hip strap does little to move weight off your shoulders.
Pros & Cons
What we like
- Rain cover stored in a base pocket
- Ripstop nylon resists snags
- Lots of pockets for the money
Watch out for
- Thin hip strap, no frame
- Not for heavy overnight loads
Key Specs
- Capacity: 40 liters
- Fabric: 210D ripstop nylon
- Rain cover: included
- Frame: none (soft back)
- Hydration: bladder-compatible sleeve
2The LOVEVOOK 40L comes with three packing cubes, so it is ready for a trip out of the box. LOVEVOOK lists it at 18 x 14 x 8 inches and markets it for budget-airline size limits.
Four compartments and many small pockets make it easy to separate clean clothes, electronics and toiletries. It is one of the most popular women’s-styled travel backpacks on Amazon, though the cut and straps are unisex enough for most travelers.
Pros & Cons
What we like
- Three packing cubes included
- 18 x 14 x 8 in footprint
- Lots of small pockets
Watch out for
- Soft back, no frame
- Organization can feel busy
Key Specs
- Capacity: 40 liters
- Size: 18 x 14 x 8 in (brand listing)
- Extras: 3 packing cubes
- Compartments: 4 plus pockets
3The Nerlion 40L is a simple, light hiking and travel pack. Nerlion lists the bag at 0.9 kg, and the thick nylon is treated to resist water and abrasion.
One main compartment, several zip front pockets and two side pockets keep it easy to pack. It is a good all-rounder for students, casual hikers and travelers who want one bag for many uses without spending much.
Pros & Cons
What we like
- Light for a 40L pack
- Water-resistant nylon
- Simple, easy layout
Watch out for
- No frame
- Basic hip strap
Key Specs
- Capacity: 40 liters
- Weight: 0.9 kg (brand listing)
- Fabric: water-resistant nylon
- Pockets: main, front zips, 2 side
4The IGOLUMON is a featherweight, packable 40L bag that folds into its own pocket, which makes it the backup pack we would throw in a suitcase or carry-on for day trips once you arrive.
It has one main zip compartment, two front zip pockets, two side pockets and a separate wet pocket for a damp towel or swimsuit. There is no padding to speak of, so it is not a pack for long days with heavy gear, but for a market run, a beach day or a light summit walk it does the job and disappears when you are done.
Pros & Cons
What we like
- Folds into its own pocket
- Separate wet pocket
- Very light for its size
Watch out for
- Thin, unpadded straps
- No hip belt support
Key Specs
- Capacity: 40 liters
- Fabric: nylon
- Design: packable / foldable
- Pockets: main, 2 front, 2 side, wet pocket
- Frame: none
5MATEIN’s carry-on backpack is one of the most widely bought budget travel bags on Amazon. Unzip the expansion panel and it grows to about 45 liters, enough for packing cubes, a toiletry kit and a camera bag.
Unexpanded, it is designed to fit standard overhead bins. It is a soft, simple travel bag, so it suits occasional travelers and weekenders more than people who walk all day with a full load.
Pros & Cons
What we like
- Expands to about 45 liters
- Low cost
- Plenty of organizer pockets
Watch out for
- No frame or real hip belt
- Expanded size can exceed limits
Key Specs
- Capacity: up to about 45 liters expanded
- Design: expandable carry-on
- Use: weekend and occasional travel

How to Get the Most from a Budget 40L Backpack
Budget packs have improved a lot. You can get rain covers, many pockets and even internal frames for much less than a premium pack. Here is how to choose wisely. For a closer look, see our guide to the best 40L camera backpack.
- Check the stitching and zippers. Reinforced stress points and solid zippers are the biggest durability factors.
- Look for rain covers. They are a cheap way to keep your gear dry.
- Do not overload frameless packs. Keep them under about 20 pounds.
- Read recent reviews. Budget brands sometimes change materials between batches.
For occasional hikers and travelers, a well-chosen budget pack is all you need. If you hike every weekend or carry heavy loads, a premium pack will last longer and carry better. For a different angle, see our picks for the best 40L backpack ultralight.
What Fits in a 40L Pack
A 40-liter pack is enough for a fast overnight in summer, a hut trip, or a week of travel if you pack light. A typical summer overnight load looks like this:
- Ultralight one-person tent or hammock (2 to 4 liters packed)
- Compressible sleeping bag rated for the season (5 to 8 liters)
- Inflatable sleeping pad (1 to 2 liters)
- Stove, fuel and small pot (2 liters)
- Food for one to two days (3 to 5 liters)
- Rain jacket, warm layer and spare socks (5 liters)
- Water: 2 to 3 liters in bottles or a bladder
- Ten Essentials: navigation, headlamp, sun protection, first aid, knife, fire, emergency shelter
If your sleeping bag is bulky synthetic, or you hike in shoulder season with heavier layers, step up to a pack with an extension collar or roll-top, like the Naturehike Rock 40+5 or Haimont 40+15. For travel, 40 liters holds about five to seven days of clothes with packing cubes. We cover this in more depth in our roundup of the best 40L backpack travel picks.
How to Fit a 40L Backpack
Fit matters more than brand. A 40-liter pack with the wrong torso length will hurt even if it is made from the best fabric. Measure your torso from the bony bump at the base of your neck (the C7 vertebra) down to the top of your hip bones. That number, usually between 15 and 21 inches, tells you which size or adjustment range to choose. You may also find our guide to the best 40L backpack for travel helpful.
Load the pack with about 15 pounds before you adjust it. Then follow this order:
- Hip belt first. Center the padding on your hip bones and tighten until it carries most of the weight.
- Shoulder straps second. Pull them snug so they wrap your shoulders without lifting the hip belt.
- Load lifters third. On framed packs, angle them about 45 degrees to pull the top of the pack toward you.
- Sternum strap last. Clip it about an inch below your collarbones, just tight enough to stop the straps from sliding outward.
If the shoulder straps leave a gap above your shoulders or the hip belt sits on your waist instead of your hips, the torso length is wrong. Packs with adjustable back panels, like the Osprey Kestrel and Kyte, solve that without exchanges.
