Umpqua's best-selling Ledges 500 ZS is the essential fly-fishing pack. Its suspended back panel/ABS frame sheet provides all-day comfort, support, ventilation and easy rotation like no other waist pack on the market. The primary pocket holds four large boxes and this updated version has “portfolio-style” dividers that allow easy box organization and easy in-and-out. The dividers also collapse which allows the whole space to be used for larger items if preferred. A top loft pocket provides accessory storage and organization. Two Zero Sweep™ retractor stations, a high-wear tool sheath, tippet pockets and a Zero Sweep™ foam fly patch round out this quintessential fishing pack.
