I was curious to see how Mont’s new Zero Superlight sleeping bag would perform in moderate conditions so with a suitable forecast I planned a trip into the mountains.
This bag is pretty special as it uses incredibly light 7 denier fabric and 1000 fill power down. This means that 1 ounce of down will fill 1000 cubic inches of volume when fully lofted. And the denier? A 9 kilometre length of 1 strand of shell fabric used to make this bag will weigh 7 grams. Impressive numbers with a standard bag weighing just 417 grams.
There aren’t many manufacturers worldwide using 1000 loft down as it is very scarce and expensive.
I always store my sleeping bags hanging from a ceiling hook so they maintain full loft and when I took this bag down to stuff it into its stuff sac the best word that comes to mind is “springy”. The bag just wants to expand and spring back out of the stuff sac. It was a very pronounced quality.
Along with my Mont Moondance 1 FN tent the bag allowed me to reduce my pack weight to 16.5 kgs. That included 4.6 kgs of camera gear so it was a very light pack.
The Zero Superlight is rated to 8°C degrees for a cold sleeper and 2°C for a warm sleeper. I sleep warm so using this bag as part of a sleep system could make this a versatile option for summer bush trips in Tasmania …. when the forecast is reasonable. I always carry a Guide Hoodie Primaloft insulated jacket and a Powerstretch balaclava and these teamed up with the Zero Superlight could make it suitable for mildly sub zero temperatures.
On this trip the temperature dropped to 2.5°C and just wearing my Mont Powerdry long sleeve thermal (and a silk inner sheet) I was quite comfortable in the Zero Superlight bag.
It was a nice escape carrying a light pack :)

We were probably twenty electrolyte tablets deep each, feeling more like science experiments than cyclists. Add in sketchy tarmac with trucks roaring past, hogging the whole shoulder, and you had a section that demanded laser-sharp focus…

I had brought my Mont Helium 680 with me. A luxurious bag rated to -12°C for warm sleepers, it is perfectly suited to Tasmania’s cooler months. Ice crusted the ground and tent the next morning and checking my temperature sensor I was surprised to see that the temperature had dropped to -7.7°C overnight. That is remarkably cool for late October in Tassie!
