I had long in vain for a matching bag for my Gitzo tripod travel GT1542T with head G2180 wanted (total length with mounted head about 50 cm). The Gump bag fits perfectly, is well padded on the sides and has a (not very stable) inside pocket for accessories (eg removable storage and tool). The double zipper goes over the top and a narrow side and is free sewn, so that it can be easily changed if necessary. The measurements given are the internal dimensions (image is misleading), the outside is approximately 53x14x11 cm. The Velcro cuff on the carrying handle can separate you, if the noise disturbs. The simple shoulder strap (with carrying upholstery) is hooked on rotating metal carabiner in the metal eyelets, the combination caused a klimperndes wearing noise - suboptimal for game viewing, but you can come up with an alternative solution itself. Conclusion: Super value for money, solid enough for a lightweight tripod, easy to repair. Strong buy recommendation!
