Designed to be roomier than the 'Nook Sack, the Big Fanny adds more volume and can hold damn near anything you need for a full day chasing fish. Sling it, wear it around your waist, or both! The comfortable waist strap helps distribute any added weight, the large main pocket keeps your largest fly boxes together, 2 smaller internal pockets help organize your leaders and indicators and a zippered outer pocket keeps your tools handy.
