HyFin Vent Chest Seal - 개별

I keep one in my car kit and one in my range bag. The compact size makes it easy to stash anywhere, and the adhesive backing stuck firmly when I tested it on a training dummy.

Finally got around to adding one of these to my trauma kit, and the compact size means it actually fits in the side pocket without bulging. The adhesive backing peeled off cleanly and stuck firmly to my practice surface, so I trust it to stay put in a real emergency.

The adhesive on this vent held firm during a first aid drill with heavy sweat involved, which is exactly what I need for field use. The single-use design is straightforward to tear open even with gloved hands, and the whole thing disappears into my pack without adding bulk.
