<p>I use a Lowepro Transit Backpack 350 AW for my RB67 kit. It can handle the RB with 4 lenses (not sure my back could handle all 6!), 4 120 backs, L handle, Sekonic L-558, lens filters, 3 lens hoods, film etc. And I can hang my tripod on the side (it has a strap for it there).<br /><br />Much much more comfortable than my side-carry bag I was using.</p>
