Jetboil has almost become a generic name for solo cooking systems and with good reason – they started the revolution and have stayed ahead of the game since – now with a range of stoves. The Sumo is their heavyweight – a group-sized cooking system with a gargantuan 1.8L cooking pot, which is ideal for boil-in-the-bag meals or melting large quantities of snow. It’s super fast: less than 3 minutes for 0.5L when I measured it; and the regulator will ensure reliability in a range of temperatures. It’s also very easy to use and stable. At less than 500g, it’s a lot lighter than it looks; and it packs away incredibly neatly – the tripod fits inside the lid and the burner inside the pot along with a 230g gas canister if needed, or with room to spare with a 100g one. The piezo ignition worked first time, every time – convenient rather than essential – and there’s a range of optional extras available that’ll make it even more useful on expedition.
