Rank #7 in Best Hiking Backpacks 2026: 10 Ranked, and Only Two Match Their Litres
RAINSMORE 40L Military Tactical Rucksack, Black
Price and rating as shown on Amazon when we collected them. Both change.
The RAINSMORE Military Tactical Backpack is number 7 in this guide. It is a 950 g polyester rucksack at £15.99, rated 4.4 out of 5 from 132 ratings, with five compartments, seven pockets, MOLLE webbing and a water-resistant finish.
Its own listing gives three different answers on capacity. The title, the size field and the storage volume field all say 40L; the first bullet says 43L; and the dimensions printed in the same listing, 33 x 27 x 52 cm, multiply out to 46.3 litres. That runs against the pattern in most of this guide, because here the arithmetic lands above the number on the label rather than below it. A different number fails to add up in the other direction: the star breakdown beside the 4.4 average counts 74, 6, 12, 5 and 3 ratings, which comes to 100, not the 132 the listing states. Everything on this page comes from the Amazon listing; we have not tested the pack.
