Mont // Brindabella Hydronaute XT

Totally redesigned, the Tapered Rectangular Sleeping Bags are warmer and lighter than ever before. Featuring the Radial Arc Baffle System and DWR Loft down fill, these bags set a new benchmark in sleeping bag performance.

The versatility of the Mont Tapered Rectangular sleeping bags 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.

The Brindabella is the most popular sleeping bag in the Tapered Rectangular range, and it will keep you comfortable in temperatures as low as -11ºC.
