Alpkit stingray frame bag, purchased from the alpkit warehouse but sadly it’s too big for all of my frames. Measurements are on the image, it is 56cm long at full stretch but squishes down to 53/54 when fitted. Two zips into one large compartment, with horizontal Velcro inside to partition the large compartment. In mint condition, comes with 4 Velcro securing straps, zips still perfect and all completely waterproof. Collection welcome or I can post. Offers accepted.
