The E660 XX-Large Lens Pouch II from Kinesis provides a secure transport and storage solution for a Canon 200mm f/2, 300mm f/2.8 IS, 400mm f/4 DO IS, or Nikon 300mm f/2.8 with the hood in the stowed position and with the leatherette cap in place. It is also designed to provide room for a lens's tripod foot. Compatible lenses within this pouch are protected by a 3/8" (10mm) closed-cell foam lining and a 1/2" (13mm) Kinesis PolyCore insert in the bottom.

This Kinesis pouch is compatible with both the Kinesis TwinBuckle Attachment System and the Kinesis Attachment Tab System (KATS) for ease of use with Kinesis belts, while built-in D-rings allow for attachment to a harness or shoulder strap. The weather-resistant lid features a touch-tab fastener for quickly removing and stowing a lens while shooting. In instances between shots where quickly withdrawing a lens is less of a priority than making sure that it sits securely within the pouch, the lid can also be zippered shut.

The exterior consists of 500 denier nylon for water-resistance and also includes a rear hand-grab loop that can be tucked away behind the pouch when used on a belt.
