Alright, here are some pictures of the smaller pack from Grey Ghost (Tactical tailor Fight Light series).
Pack is perfect for a PC. Attaches using malice clips and QASM buckles. Pack comes with replacements for both.
Side view. Hangs just a bit off the PC but thats mostly because of it being on the ground. While worn its not too bad.
Both pockets open. No organization/admin.
Inside main pocket. You can barely see them, but, on the inside under the zipper are two elastic pockets that will fit a water bottle size item. You could probably fit an MBITR in there but I dont have one to show you.
Lastly, a sleeve to store the shoulder straps and hydration bladder. There is a piece of webbing with a triglide to hang the bladder from.
Overall, this is a fucking steal for $59. Super lightweight and prefect size. I was looking at a Yote or MAP but this seems like it will do the trick. I'm very minimalist when it comes to my gear and what I carry so the size is not an issue for me.
BTW, the atacs is pretty sweet. Get it while its HOT!
