Cressi Spring Load Catch Bag
The bag's "lid" is a Spring loaded clasp that is made from stainless steel and can easily be opened with a squeeze from one-hand. To empty the catch simple un-zip the bottom of the bag!
When not being used, the bag folds in half and can be stored like this using the buckle to keep it together
The large model has a hand pocket on the front of the PVC which is great for keeping other tools that may be required.
