Brightline bag components work only with the Flex System line of bags.
Designed to hold a large hand-held radio or a water bottle.
The zipper conceals an expansion flap to allow wider objects to fit.
The top "cover flap" is adjustable to allow it to go up "over" and secure taller items. (Like a compact umbrella?, etc.)
The Side Pocket Alpha is a tall single-compartment pocket that is designed to hold a large hand-held radio. ANY large radio will fit. The antenna can stick up out from the side of the top flap.
OR, you can also store a water bottle up to 20 oz. To accommodate larger bottles we offer the Side Pocket Echo.
There is also an external slot that can hold either, (a) a standard pen (see the Gallery), (b) the detached antenna, or (c) a glass-rod fuel gauge.
In addition, the top "cover flap" of the Side Pocket Alpha is adjustable (and removable) to allow it to go up "over" and secure tall items like a tall bottle or a compact umbrella. See the Instruction Sheet for more information. And the Velcro tab is now "extra wide" to provide good "grip" when the expansion zipper is opened for wider objects.
