Waterproof 420 denier nylon raincovers are available in two sizes and created to fit the tapered shape of the AIM® drag bags. The small raincover is designed to fit the AIM® 40, 45 and Folding Stock drag bags whilst the large raincover is suitable for the AIM® 50, 55 and 60.
 
This is a useful accessory that fits over the drag hood and under the base of the bag to guard against rain and mud. It does not obstruct the use of the rucksack shoulder straps. Fit it in seconds without the need to tighten straps. After use, the raincover packs up small and can easily be put into a coat pocket.
