Recommend me a backpack

Upgraded a bunch of my gear over the winter with more additions to come and have out grown my current flipside sport 10L AW. Want to stay with a backpack for its convenance and comfort while walking around the racetrack or trails in the woods. Would need to be large enough to hold all of my gear currently listed with hoods as well, As have room for an additional few lens. (24-70 F4 IS, 100L, etc). Also needs room to fit a MH-C9000 battery changer for weekend long trips to the track. Would like for it to be water resistant. What bag would you suggest? Thanks!

Check out f stop. They have a great range of bags that would suit you.

What is your budget ?

Best thing to do: bring your gear with you to a shop and try out some bags.

I use a De Kata MiniBee 111-UL backpack Thats fits a 5D3 -16-35 II - 24-70 II - 70-200 II - 100 L. Macbook Air 13 - lee filters etc tripod. And yes its a small bag

Would like to stay under $200. Has anyone used the F-stop street pro? I searched and couldn't find much on here about it but, I'm leaning towards getting a pelican 1560 to transport my gear to the track in then just get s slightly larger bag then I currently have to keep it light weight and comfortable and just during breaks in the racing action go swap gear between it and the pelican. The bag would need to be able to hold least my gripped 60D, 10-22, 17-55, 70-200 and flashes/triggers, which f-stop says the street pro will do.
