Hi Tom!<br>A few years ago I bought a TYVEK-fabrik, aluminized, Emergency-Bag here in Germany. The Bag was build for the use in Liferafts. I guess it is SOLAS-approved. I didn`t test it in the field, but I would prefer a normal Emergency Bag like Coghlans Brand. It`s more ligthweigth and cheaper, without doubt, the TYVEK-Bag ist more durable.<br><br>By<br>Chris<br>
