As above, think tank retro 20, brand new, (tags, etc.). I impulse bought without measuring. I thought it would hold my D3 with 70-200 2.8 and my 14-24 2.8----it will but it is just too tight! Otherwise, a really nice bag-very comfortable on the shoulder. They sell from B&H for $169 $115 including PP fees and shipping, (con usa).
