Bill Stone and Nalgene Sleeping bag

[GypsumWolf]

Bill Stone on the Journey Towards the Center of the Earth video stated that they found a sleeping bag that would fit in a Nalgene bottle. Does any one know what bag that is and/or where to get it?

This may not be what you're after (I'm not familiar with the video you mentioned), but I have a sleeping bag that packs down to about the size of a 1-liter Nalgene (though I've never tried to actually get it into a Nalgene bottle). It's only useful for warmer climate camping/caving (like Lech for example), but it is really cheap.

I prefer the mummy version, but have also used the rectangle one quite happily. Basic, cheap, small, and light. They work great!

That website says the mummy version is sold out. Too bad, that's a good looking bag at a great price.

Slumberjack. Try campmor. And it's not a 1 liter Nalgene!

Google TechTalks July 27, 2006

Bill Stone, Ph.D., President Stone AeroSPACE. Bill will be a speaker at the TED conference next year. ABSTRACT We live in an era when Earth has been considered long-conquered. The highest mountains, darkest rain forests, the Arctic and Antarctic wastelands have all been explored and mapped. The ocean’s deepest points have been plumbed and detailed isobenthic maps exist. These former frontiers are now relegated to places for ever more detailed scientific investigations (especially the oceans for their bio-diversity), extreme sports, and for commercial exploitation. But as places for true exploration they are a part of history.

While truly known only to a handful of teams worldwide, the last -- and arguably the most technologically and psychologically challenging -- terrestrial frontier is being systematically explored in our time: that of extraordinarily deep cave systems. And, like the original exploration of the Poles, and the race to climb Everest, there is a quiet, yet spirited competition now to explore the once-and-for-all-time deepest natural abyss on Earth.

This talk explains the origins of the U.S. effort, the nature of expeditionary deep caving, and introduces the audience to the world of Sistema Cheve and the technology that has been developed to explore it.
