The Best 40L Backpack Reviews: Our Top Picks

When backpacking, camping, or hiking, you don’t always need a backpack you can fit your vehicle in.  Sometimes, especially if you’re a productive and effective packer, you can bring everything you need and not worry about packing all the extras and the kitchen sink.

Unless you’re planning on getting lost, then normally you won’t need anything bigger than a 40L pack.  Even students, from elementary to college, can make use of a 40L.

The Osprey Farpoint 40L Backpack is actually discussed in a category further down, but even though it is a tad pricey, it is definitely worth every penny.  Whether it’s used for carry-on, hiking, camping, backpacking, or even all 4, this bag definitely won’t let you down.


2. G4Free — Cheapest 40 L Backpack

[amazon fields=”B00YGJ724I” value=”thumb” image_size=”large” image_link=”″ image_class=”ais350″]

The cheapest, yet most effective 40 L backpack that I’ve found is the G4Free Outdoor Military Backpack.  With an assortment of pockets, durable material, and innovative MOLLE systems designed on the backpack itself, this bag, under$30 on, is a must-have for outdoorsmen.  Most of the reviews available for it say the same things.

Wolfgang Unger said “Just a tough and functional backpack. I teach Algebra 2 at a high school and this is much better than a cart. Holds two teacher’s editions, my test and quizzes answer key binder, lesson plan binder, several spiral notebooks, about 50 pens in the small top pouch and the lower small pouch holds steno pads and other similar items nicely. The zippers are very sturdy and durable. Have had it for several months without any problems and I use it every day! Very happy with it.”

Likewise, Joshua Smith said “… This backpack is the perfect size for a 48 to 72-hour pack. . .  Even though I have only had this pack for a month the stitching appears to be very sturdy. Straps are thick and most of them, with the exception of the upper part of the shoulder strap, are doubled over at the ends and stitched so they don’t come through the tightener.”  All-in-all, this backpack isn’t too shabby for only $25.00.


3. G4Free — Best 40L Backpack for Hiking

[amazon fields=”B0721PFTWN” value=”thumb” image_size=”large” image_link=”″ image_class=”ais350″]

The Osprey Tempest 40 Backpack, with its AirScape back panel, is a lifesaver on those long, uphill hikes.  Roomy enough to pack everything you could ever need, and a dead body, and durable enough to not worry about the brambles and briars on the trail, this backpack is perfect for any avid hiker or professional hitman.  The magenta color, however, might get you laughed at while attending the contract killer wet-works meeting.  Sites, on, said “I have never loved a bag the way I love this Osprey.

I am small framed and ordered the XS/S. It fits so comfortably.  I have had this bag for 5 months and I feel like I’ve already gotten my money’s worth. I took this on a 4-day trek through the Austrian Alps. I did not have to pack a tent (We stayed in huts) but it fit everything else I needed and it all felt so lightweight because of the fit of the hip-belt.

I have also used this as a carryon for most major airlines in Europe. I’ve used this 3 times with Ryanair so far and there has never been any anxiety that my bag won’t match their restrictions.  I adore this bag and I am so happy to have it as an adventure partner!”  Basically, this bag is so awesome, who needs another person to adventure with whenever you love your backpack that much?
