Without more information, I'm a little skeptical whether these tents would stand up to real world usage. It'd also be nice to see some good ole fashioned expedition reports because the design seems a bit fragile to me. For example, can you patch those high pressure air channels with duct tape?

And that insulated winter tent looks kind of cool but I'd like to know someone has actually used it in extreme conditions before they make that marketing claim. Maybe they should donate some to the US Antarctic Program for evaluation? <img src="/images/graemlins/grin.gif" alt="" />
