Nadgee Hydronaute XT


Waterproof model.

Totally redesigned and newly released - our tapered rectangular sleeping bags are warmer and lighter than ever before. Featuring our new patented Radial Arc Baffle System and Radiant Barrier technology, these bags set a new benchmark in sleeping bag technology. The versatility of the Mont Tapered Rectangular sleeping bags will make them a favourite with bushwalkers and ski tourers. They can be used over a wide range of temperatures by regulating the ventilation with foot and side zippers and adjusting the distribution of down between canopy and base. The semi rectangular shape also makes them ideal for those who like a little more room to move when they sleep.
