The Rab Quantum Top Bag is a 32 degree F (0 degree C) minimalist top bag weighing only 16.0 ounces (454 g, regular width). Its light weight is the result of a simplistic design: no zippers, draft baffles, hood, or bottom insulation. The Q-Top is a top bag, designed to be used in conjunction with a sleeping pad to provide insulation on the bottom. We found a lot to like about the Rab Quantum Q-Top, but we also found some major design problems that wrecked its ratings.
