The complete guide
Fabric weight and why it matters more than the price tag
The ProCase 40L Tactical Backpack is sized for a 3-5 day loadout, built from nylon. With 5 pockets and compartments, packing it doesn't mean everything ends up in one bag-shaped pile, the MOLLE front panel is there for whenever you add pouches, and shoulder strap does the actual carrying once it's full. 10,739 reviews and a 4.6 out of 5 average on the source listing back this one up; that's the kind of track record that's hard to fake. Folded flat it measures 30.5D x 35.6W x 10.2H centimetres, and it's priced at £63.98.
