The black WaterShed Padded Liner for Chattooga is constructed from a 200 denier nylon exterior and hook and loop receivable fleece interior surrounding 1/2" closed-cell foam. It offers a tight fit inside the bags for which it is offered. All liners have a zippered top, buckles on each end for compression, handles, and hook and loop-receivable inner walls designed to work with the Chattooga Divider set. The Chattooga Liner and Divider set combo work great together. They have already been extensively tested by Watershed team 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.
