Arc’teryx Cierzo 25

Arc’teryx’s Cierzo 25 might pack 25 litres worth of supplies, yet it only weighs 400 grams and packs into its own pocket. It’s great for climbs and treks, though it’ll do just as well for ventures into the city on hot summer days: pack it up when it’s no longer needed and hang it from a belt loop… or something. Other selling points include water resistance, a drawcord to compress the single large compartment and a bunch of external loops that we’ll never use for their intended purpose – holding ice picks.
