I wonder if they make those pants with a XXXL snack sack and action zone because I find just XL is too tight for my snacks.
You'll find spraying with a pressure pack is not that hard if you use the nozzle on top rather than punching a screwdriver through the can and doing it that way. I had this crazy idea about getting one of those woven synthetic feed sacks, cutting it up and gluing it to a base with spray adhesive and then painting over it with gloss black. I reckon the end result would look like carbon fibre, but then I might be quite mad.
