Built for maximum durability in any type of fishing environment, the Plano Z-Series Tackle Bags offer efficient and convenient tackle storage options with the ultimate protection from the elements. The Z-Series Tackle Bags feature a rugged 500D PVC Fabric construction that is completely waterproof. Fitted with a waterproof molded rubber base with non-slip inserts, these bags are designed to remain in place while on the deck of your boat while preventing the bag from absorbing water up through the bottom. The main compartment is spacious enough to hold 4 Plano StowAway Utility Boxes (2 included) and features a zipperless heavy duty buckle closure design that eliminates the hassle of zipper failures and corrosion over time. This zipperless design, along with the rugged waterproof construction make these tackle bags well suited to handle the rigors of saltwater environments. Multiple hardware attachment points allow you to attach tools and additional accessories to the bag.
