The G4Free 40L Molle Backpack is the top pick in this guide, and it is the rare case where the number in the product name survives the arithmetic. The listing gives the size as 30 x 28 x 48 cm and the capacity as 40 litres; multiply those dimensions out and you get 40.3 litres. Of the ten packs compared here, only two reach the figure printed in their own name, and this is one of them. The others do not come close — the pack sold as 70L is listed at 67 x 30 x 10 cm, which is 20.1 litres, and the 50L at 62 x 30 x 15 cm, which is 27.9 litres.

At £33.99 it carries 4.7 out of 5 from 3,626 ratings. The listing describes 1000D polyester with double stitching, 2-way zippers, MOLLE webbing on the front and sides, D-rings on the shoulder straps, and a weight of 1.25 kg. It is hydration compatible and takes a 3L bladder, which is not included. Not every field lines up, though: the specs list 3 compartments and 3 pockets while the bullet text describes 2 main compartments plus 2 front two-way zipped pockets, and "fit type: snug fit" is a clothing field that has travelled with the listing. Everything on this page is taken from the Amazon listing, not from our own testing.

**Does the G4Free 40L Molle Backpack really hold 40 litres?**

The listing gives the size as 30 x 28 x 48 cm and the capacity as 40L. Multiplying those dimensions gives 40.3 litres, so the name and the measurements agree here. A soft bag bulges when packed, so read both figures as the floor rather than the ceiling.
