The HyFin Vent Compact Chest Seal Twin Pack provides users with two vented chest seals in a compact packaging for the treatment of penetrating injuries to the chest. Designed with 3-vented channels that allow air to escape the chest cavity during exhalation but prevents airflow from entering through the injury site during inhalation. Each HyFin Vent Compact Chest Seal is 4.75 in. x 4.75 in. and made with advanced adhesive to provide a superior adhesion in the most adverse conditions, including sweaty or hairy casualties.

Packaged in a rugged, easy-to-open foil pouch, the perforated packaging allows users to open only one dressing at a time as needed. Its small packaging is ideal for low profile kits as you do not have to fold it to get it to fit in your kit, go-bag, cargo pocket or body armor.
