The Lion Fish bag has been improved to help prevent spines from sticking the user. The latest version has a backside (the side held closest to the user) that is made of a tough 18oz vinyl coated fabric that will help minimize things sticking through it. (Disclaimer: No fabric will prevent all penetration under all circumstances. Larger fish, with stronger spines, can in some circumstances poke through this and other materials. Our bags are designed for the best combination of function, usability, and efficiency).
The NEW model provides extra protection on the side of the bag nearest the diver. The other aspect of safety is to move the location of the Lion Fish, that are already in the bag, further away from the hand that inserts the fish into the bag. So the new model moves the insertion point to the top of the bag and farthest away from the bottom of the bag, where the caught lion Fish will be located.
