wow!
how much stuff are you talking stalking!?
what is the slip for? transport or to actually take out stalking?
I have a cheap and cheerful nylon on with faux sheepskin (which is a pain in the arse as it keeps fluffing up my bipod!) and a canvas non zip flap and buckle closer. its caked in crap on the outside the bolt has worn through the canvas and now has a bespoke leather patch on it and the scope area
the nylon one is rustly, zip is noisy, fluff bugs me.
the other one goes on missions
