Think Tank Skin 75 Pop Down V3.0. Part of the Think Tank Modular Belt System V3.0, the Skin 75 Pop-Down V3.0 Lens Pouch is a lightweight, compressible pouch designed to hold one telephoto zoom lens with its hood attached. Its unique Pop-Down design allows you to vary the length of the bag to accommodate leaving the lens hood on, and it features an interior pocket for smaller accessories as well as a front zippered pocket to hold lens caps. The pouch's design has a drawstring closure for quick access, and for a more secure closure, Sound Silencers hook-and-loop fasteners are also featured. The pouch's exterior is constructed from 420D nylon and 600D polyester, with a water-repellent coating, and a seam-sealed rain cover is also included to protect the pouch from the elements. Its design also incorporates a grab handle and additional attachment points, and the pouch can be rotated or locked in place when attached to a compatible Think Tank belt.
