Ahem. Where was I before I got sucked into a flaming contest? Oh yes - field data on the subject TPA.

I have checked out a few other forums and basically found that people know of this bag but haven't actually used one or encountered any objective evaluations of same. I did find a one paragraph reference from a hiker who reported that since the bag depended upon reflectivity for effectivess, he found cold spots - namely, where his body met the bag and the back met the ground. Not much data on other variables, though.

I tried contacting several of the references provided by the manufacturer of this bag. To date, not one of them has replied to me. Don't read anything into that - just a report.

I guess I'll have to think about getting one donated an putting it through an immersion test. Lest I get flamed anew, recall that my interest is in determining if this product has any redeeming features for a short-term immersion situation.

Let me know if you hear anything or have an experience with the product.
