How does this compare to the Flame IV? Which would you recommend for a cold sleeper for winter camping, but also year round use? Does this bag have condensation issues like the Flame?
G'day Erica,
The Altitude At2 and Flame Fm4 are both excellent bags, with slightly different features. They both have a comfort temperature of -10'C, so in that regard, you'll experience the same level of warmth from both bags. The Altitude has a little more flexibility with space and zipper configuration, so will be a little more comfortable, and easier to open up, or half-open up for year-round use.
In regard to condensation, there will always be the possibility that condensation will form on the top of a sleeping bag in very cold weather, due to the very nature of condensation and the relationship between body temperature, and tent temperature. Both bags feature ULTRA-DRY Down™ to help reduce the impacts of this moisture on the down.
Looking for a sleeping bag to use when camping at Perisher or Thredbo in NSW for a 170cm tall regular size woman
G'day Margaret,
This sleeping bag rated at -10, if used with a complete sleep system - insulated mattress, thermal liner and thermal pillow plus a 4 season tent should help to keep you nice and toasty. Obviously, there are many factors that come into play such as if you're a cold or hot sleeper, sleeping attire, weather conditions etc that might affect how warm you'll stay, but this will certainly go along way in helping to keep you warm.
Hi, I'm 173cm tall and wondering whether I'd be fine in the regular size bag or need to purchase the long?
G'day Mel,
Based on the recommended maximum height of 170cm for the Regular I would suggest going for the Long. However Lauren from the video is 171cm and she indicated that she felt like she had a fair amount of wiggle room, so you might be ok in the Regular length if you sleep curled up a bit.
Im looking for a sleeping bag that isn't a mummy shape but still has enough warmth for snow camping.
G'day Celesta,
The Altitude At2 has a comfort temperature of -10, so as long as you're sleeping on a well-insulated mat in a 4 season tent then we'd be pretty confident that you should be ok in this bag. It would be worth checking the weather conditions though, as I know you can end up with pretty cold nights there in winter.
