It allows the angler to carry the priorities in a variety of ways, including use a chest pack with padded neck and waist strap, TPU coated webbing lash straps with velcro to wrap around aluminum raft frames and casting braces, or with the TPU snap tabs that allows for attachment to plastic coolers. When you want all the essentials nearby, this is the perfect solution.
The Arroyo Chest Pack is big enough to fit a nymph and dry box, but small enough to be utilized as it's meant, up front and personal. Nevertheless, if you have a hankering to move fast, engage the hip straps to transform it for lumbar use. Despite its compactness, there is plenty of space for flies and tools, and has a zippered front flap with replaceable foam for bench work. Stay nimble.
