A "Bag Insertion Rucksack" - as the official nomenclature says - helps you organize stuff, protects your gear from the elements, and reduces wear on the rucksack itself. It doesn't weigh or cost much! Proper hard wearing army kit.

You don't have to spend a lot of money to get a liner bag unless you want a one-way valve, complete waterproofness, or other specialties. The classic cheapskate method is a trash bag, but this basic nylon bag is a big leap forward and doesn't need to be replaced every two trips to the outdoors.

Made of nylon with a drawstring around the opening. Measurements flat approx. 60 x 92 cm / 23.5" x 36".

Used but in perfectly serviceable condition. Most of these were manufactured in the '90s.
