It's made of pressed steel and folds out into a 45 x 30 cm cooking area with a high enough windbreak to cope with a stiff summer breeze.
Thiscould have been the perfect answer to the prayers of those NY subway travellers who had the misfortune to be on the same train as Borat and his hens. Char-grilled chicken wings could have been the perfect way to calm everyone down. It costs $40 on its own and $50 with the rucksack.
