Re: Rebreather to the TOP!
The problem is the scrubber and the compexity of th unit, both in terms of weight and operating temperature - divers worry about "cold" water, which is tepid by comparison to the external temperature experienced by high altitude mountaineers.

you have only to see how light a composite cylinder is compared to scrubber for 8 - 10 hours that must work at -30c
