Protect your investment! You paid hard earned money for your Full Face Mask. Why not keep it in a bag designed to store it like it is supposed to be stored. The mask bag was designed to help keep your mask in the right drying position, keeping water from pooling in your 2nd stage regulator. It also has vents to keep good ventilation helping to stop mildew and drain holes to let water drain away from the mask. Lots of storage pockets as well. One is a dry storage compartment! The bag has a carrying handle as well as a shoulder strap. In all, it’s a great investment to help keep your valuable FFM stored in.
