The black Lens Bag from Shootsac is a sling-style shoulder bag that allows you to have from 3-6 lenses at your disposal quickly and efficiently. It's not meant to be or replace a traditional shoulder bag that holds your DSLR but rather it's akin to a "bandolier" where you store lenses, flashes and/or accessories.
With its slim, lightweight (7.0 oz) profile, it hugs your body with its wetsuit-grade neoprene material avoiding the needs to lug around a heavy, bulky camera bag. For the shooter who travels with a DSLR and only wants to tote around a bunch of lenses, the Shootsac Lens Bag is the answer. It is also designed to hold small accessories such as batteries and memory cards.
The Shootsac Lens Bag has six pockets. The front three have hidden elastic inserts that stretch to accommodate the lens being stored. The rear three pockets are recommended for your small accessories. The bag also comes with an interchangeable neoprene cover that serves two functions. First, since the pockets do not seal, it helps keep the dust and dirt off your glass. Perhaps more importantly, it covers up the bulges and bumps of the lenses and adds a level of security while you're on the move.
