My opinion after having several of the old eagle industries ones, don’t get the combo. Yes it’s convenient having one item instead of two but if you’re really using the mat you’re going to end up with it soaking wet, caked with mud, covered in dust, and possibly even cow/goat/dog shit. You really don’t want to wrap your rifle up in that after your done, especially if it’s wet.
I’d buy a good mat like the Cross Tac. I bought one based on recommendations and it’s worth the price. Very well padded, comfortable, and extremely heavy duty. I have no doubt it will last a lifetime.
Then get yourself a well padded quality case for your rifle, and not a drag bag because you’ll end up with so much junk in it that you can’t carry it. If you look on CDNN you can often get eagle soft cases at crazy liquidation prices.
You’ll have a mat that you don’t have to worry about what you lay it in, and a nice clean dry home for rifle when you’re done shooting.
