If weight is an issue and quality is a must, there's no better choice than the Mystique 1.5. The Mystique is a 2 pole, non freestanding tent and is the most lightweight model in the Alps Mountaineering line. But just because it is lightweight does not mean that they've cut any corners or left out any ideal features. The Mystique comes equipped with 8 zippers, factory sealed fly and floor seams, and 2 mesh doors for great ventilation and easy entry and exit. The weatherproof fly provides a vestibule over each door and has a vent that you can keep open or closed.
