Mont Brindabella XT Series Sleeping Bag


We accept Afterpay and Zip ($100min/$1000max)

Whether above or below the snow-line stay warm in chilly conditions in Mont's Brindabella series sleeping Bag.

The new vertical baffles in the Brindabella series maintain optimal down distribution throughout the bag for improved insulation efficiency. Teamed with the unique cordless collar system that wraps around your shoulders provides a marked improvement on the performance of the bag. When the collar system isn't required, it tucks neatly inside and secured to improve the ventilation.

The shell fabric has been upgraded to a higher-performing Hydronaute XT laminate with 20,000mm waterhead (previously 10,000mm waterhead) and 20,000g/m2/24hours breathability (previously 7000g/m2/24 hours breathability).

The snag-free zip has improved durability and is integrated with a down fill 2-dimensional draught tube that interlocks with the existing 3-dimensional draught tube for excellent insulation along the zip. 

The hood has a better fit around the head for greater insulation, and the drawcord has been relocated to the top of the hood for easier access.
