Our take on the Mont Helium 300

The Mont Helium 300 is a lightweight down sleeping bag rated as a 3-season bag for bushwalking and alpine use. Mont gives two comfort figures: 4°C (39°F) for women and cold sleepers, and -1°C (30°F) for men and warm sleepers. It is built for pack weight over luxury, so it suits trips where every gram counts. The best new price is $223.89 at evandorrulvane.com as of November 4, 2026, and only one store lists it new, so there is little price competition to shop around for.

Questions and answers

Is the Mont Helium 300 warm enough for winter?
No. Mont rates it as a 3-season bag, with a -1°C (30°F) figure for men and warm sleepers. Below freezing, most people will need a warmer bag or an added liner.
What is the difference between the two temperature ratings?
Mont lists 4°C (39°F) for women and cold sleepers and -1°C (30°F) for men and warm sleepers. Use the figure that matches how you sleep, not the lower number.
Is $223.89 a good price for this bag?
It is the best new price found, at evandorrulvane.com as of November 4, 2026. With only one store listing it new, there is little to compare against, so check the price history before buying.
Is it light enough for multi-day hiking?
Yes. The Helium line is built as a lightweight down bag for bushwalking and alpine trips. Check the packed weight and volume against your pack size before you commit.
How should I care for the down?
Store it loose and dry, not compressed, and wash it with a down-specific cleaner. Avoid regular detergent, which strips the oils from the down.
Does it come with a stuff sack?
Mont typically supplies a stuff sack and storage bag with its down bags, but confirm the contents with the store before ordering.
Where is the Mont Helium 300 cheapest?
At evandorrulvane.com, for $223.89, as of our latest check.
