The front opening design of this fishing backpack allows you to easily pack our battery-operated vacuum sealer and other accessories, such as your file knife and paper towels to pat dry your fresh fish before preserving. The zipper at the back conveniently holds your cutting board so you aren't stuck filleting your fish on the rocks anymore. But the part we're most proud of is the insulated top zipper, which is perfect for keeping cold drinks and food cold and preserving that freshly-caught taste of fish until it hits the grill.
