Did you know some at some places it's prohibited to use a tripod? At the same time, those places 'will allow' use of a Monopod. I wonder if the same rules apply to a Click Elite backpack with built in Camera Stand? Click Elite, best known for their camera back packs with built in camera stands are on sale at a whopping 50% off for a limited time on select models. Personally for small bags, I prefer my LowePro setup. Anything heavier, and i'm into a roller bag. But if you've been eyeballing some of the Click Elite multifunctional bags and backpacks, but were less than flattered by their high prices, this could be a small window of opportunity following this link (click here).
Here's a couple of small packs I recommended. When I just want to carry the bare minimum, my lightweight bag is a Lowepro Fastpack 100. I chose this one, because I hate the single sling setups. With the sling, there's just too much weight on one shoulder. Using the double straps evens out the weight. The really simple design also doesn't scream 'Look I have a camera in here'. I'm able to fit a Canon DSLR with a 24-70mm in the bottom area and another lens in the top part. Plenty of space for media cards, lens cleaners, and filters. If you're shooting with smaller cameras, there's more than enough room in the 100, but of course there's larger versions available too.
The Fastpack 100 is a great small pack (I actually have two), but the Flipside versions from LowePro are just a bit larger and the next step up to being able to hold a Tripod and a long lens. It's called the Flipside because of the way you gain access to the gear which is both functional for keeping things out of the dirt, and safer from pick pocketing sticky fingered thieves. If you need to hold a Tripod, carry longer lenses, or external Flashes, the Flipside 200 would be a good start. There's also larger versions of the Flipside available too.
If you were interested in that review Rod did on Calumet's BP1500 large backpack found here: http://cheesycam.com/rods-calumets-bp1500-backpack-review/, the price had gone up at the time. Checking back today it seems it's dropped back down on sale. Follow the link below and search for the BP1500.
