My old Tenba backpack is getting too small and I need something bigger. Need to hold: Nikon D5500 (small DSLR) 35 mm 1.8 16-80 zoom 10-20 70-300 Flash Assorted other small stuff. I’d also like for it to be able to hold my tripod on the outside and a water bottle. Any recommendations? I wanted something hands free so that’s why I was thinking backpack but I’d consider a bag too.
