The Ultra Hyperspace is great for lightweight mountaineers, alpinists and trekkers. The Ultra Hyperspace is Terra Nova's lightest 3 person mountain tent. The minimal weight and inner-first design will also a be a godsend for those travelling to desert or tropical climates where every gram is felt after a day in the sun, and the ventilation option of removing the flysheet totally provides cool and insect-free relief from the elements.
