Watershed's dividers are constructed of fleece and padded closed-cell foam, along with velcro attachments which are meant to adjoin to the interior of the Chattooga padded liner. These are a photographers dream! Each piece is customizable in order to design protection specific to your needs. They have already been extensively tested by our Team Watershed members and are working out perfectly with HD cameras, video cameras, as well as digital SLRs. These are great accessories to add to your current line up of Watershed products.
