Wind River Gears 8X Chest Pack is the oerfect pack for those who take the minimalist approach to gear. There are two main compartments. The front compartment has a drop down removable fly page and an interior power mesh pocket. The interior pocket has a mesh pocket and enough room for one medium sized or two small size fly boxes. The 8X also has dual floatant holders, two coil retractors, a zippered back mesh license pocket, alligator clip and a removable waist belt makes this a small pack with a lot of punch. The 8X can be clipped into a lanyard for an even more versatil tool. With scant measurements of 7" x 5 1/2" x 4" but the capability of holding all the gear you would need for a day on the stream make this a great little pack for the price.
