I gotta say i love WTFs pricing. Im tailoring myself and i can tell you prices from your known manufacturers like ferro,spiri etc are absolutely unreasonable. WTF doesnt clear your pockets out like that. And i respect it.
It may look big but it makes sense because it's made for 7.62 mags. Maybe the fanny bag it's a bit oversized... BTW is it just me or the camo in the bag has been sewn sideways?
Due to the buckle set up and that it comes with a backer you could use this as a huge Fanny pack if you wanted to a zipper insert for the rear and the gp pouch would be a nice small med bag.
