you could attach them together but it won't be a great fit. The slots at the top of the SG bag aren't big enough to fit over the top of the duplex frame.
Exo works perfectly on Kifaru though and visa versa. id try that before the SG. Never tried an SG on it. I am thinking about upgrading to a SG Pack to see how I like them out of all the big packs SG is one I havent tried out yet.
I gave the search function on here as well as googles using site:rokslide.com... with different key word combinations and quotes in different place, but haven't come across any pictures.
I figured the stay pocket would be a tad narrow, but that is an easy fix if the pockets are the right distance apart.
