The upcoming Low Profile Covert Bag looks to be a pretty versatile bag from ECHO NiNER. It is designed to serve as a stand-alone bag or as a camera insert for their X-Messenger Bag.
The Low Profile Covert Bag offers several internal organization features along with built in padding to protect its contents. You can use it to store your lenses, camera body, laptop, or anything else you want to protect and organize. The entire interior is lined with high visibility material so that your loose items are easier to find. The Low Profile Covert Bag nestles perfectly into the X-Messenger or you can use the integral handles and detachable padded shoulder strap to carry the bag on its own.
