Atom is a ultralight 13 litre rucksack that packs away to the size of your palm.
Ideal to keep in your rucksack when travelling for toting items when you don't need your main bag. Or for that stretch of ride between the last shop and your camping spot.
Made using waterproof siliconised nylon (not seam taped) giving protection from showers. The Atom has a 13 litre zipped main compartment and folds away into a zipped side pocket when not in use.
