THERMO

This is the same bag as The Jerven bag Original, about 1,45 x 1,45 meters, folded as a wind sack. And, its lined and padded. That means, that it is not only heat reflecting, but also heat insulating. In addition we have almost

eliminated the condensation problem.

During testing in the winter of `95 we had, inside The Jerven bag Thermo, a rise in temperature of unbelievable 29º C. (84°F). Outdoor temperature -14º C. (15°F), and inside the Jerven bag +15º C. (59°F). The only heat source was the

person inside the bag! The Jerven bag Original reached +9 C. (48°F) in the same test.
