A place to chat about gear and the philosphy of ultralight. Ultralight bushwalking or backpacking focuses on carrying the lightest and simplest kit. There is still a good focus on safety and skill.
Forum rules
Ultralight Bushwalking/backpacking is about more than just gear lists. Ultralight walkers carefully consider gear based on the environment they are entering, the weather forecast, their own skill, other people in the group. Gear and systems are tested and tweaked.
If you are new to this area then welcome - Please remember that although the same ultralight philosophy can be used in all environments that the specific gear and skill required will vary greatly. It is very dangerous to assume that you can just copy someone else's gear list, but you are encouraged to ask questions, learn and start reducing the pack weight and enjoying the freedom that comes.

Did I tell you all about my new super ultralight highest tech sleeping bag that's rated for -30 deg C? It's barely 80g and compliments your existing triple layer down jackets and insulating pants. Tested on the dark side of the moon. $2999 each with free P&H. Choice of colours.

PS. I now claim world's lightest sleep bag title.

Shti, I've just noticed my left leg is longer than my right. ? Coincidence?

You forgot to mention the battery weight, don't the battery packs for those sleeping bags weigh 31 kilos??

You could swap out the old swiggle for one made on unobtainium and cut the weight to 78 grams.

The most interesting application for these superlight bags is to use them to push your regular 3 or 4 seasons bags into the next season. Like a 0C turned into a -10C, or a -10C into an expedition worthy -20C (if their +10C rating is to be believed). It could also be excellent to use with a quilt in cold conditions where the inner bag would seal out drafts too. For 240 grams that seems pretty darn amazing. The main downside I can see is that adding fabric layers decreases breathability somewhat.
