Bag’s exterior is made from a combination of 420D Nylon NT and 450D Rip-stop fabric for strength and durability. The interior lining is 150D Polyester fabric. Offering lots of gear carrying capacity, the bag folds into a compact package for storage. Large main compartment, two front pockets and two inside pockets provide a variety of packing and stowage options. YKK Vislon saltwater-resistant double-slider zipper is durable and makes accessing the large main compartment that much easier. Backpack system plus top handle with reinforced “off-road” skate-style wheels provide multiple transport options. The updated Porter Bag carrier offers lots of volume to handle your dive gear. A bit smaller than its predecessor, it comes with reinforced “off-road” skate-style roller wheels plus a backpack system, so you’ll be able to easily roll or carry the bag wherever you want to go. But what’s really great about the Porter Bag is its easy-fold feature that allows it to be stowed away compactly as it awaits your next dive adventure.
