What a sub-20 litre pack holds

Lunch, a fleece, a litre of water, a first aid tin and a shell layer, with room left for hat and gloves. Fill it past that and you start forcing the zip, which is where a day pack fails first. Keep the dense items against your back and let the straps do the work.

Fold it away, or use it as a liner

Empty it packs down small enough to live inside a bigger rucksack and come out for a summit push. It works the other way as well, holding wet kit apart from dry clothing in a larger bag. The coating sheds a shower; under steady rain the zip and the sewn seams let water through, so wrap a phone in a sealed bag of its own.
