all fair points. To which I'd add:
1) not everyone only goes a mile in, max. I'd say most of my hunting other than local "after work" type stuff involves a mile MINIMUM, often much more. It's clear my situation (TONS of elbow room with very low deer density and pockets of habitat often involve hiking in a ways) is not the norm, which may be the more relevant issue.
2) if your requirements include only a rifle and ammo, you are not the target of the marketing push that this post is about, you are talking about a different activity. As I hear it used, the term "mobile hunting" is defined by ultra-lightweight hang-and-hunt style treestand hunting, which was the subject of the post. This was a business/marketing question, not a hunting strategy/efficacy question.
3) would you be wearing a cotton sweatshirt and street clothes if you were 3 or 4 miles into a wilderness area filled with mountains, bogs and swamps, with daytime highs in the 30's, and often threatening a rain/sleet/snow mix? I would not, despite agreeing that a cotton sweatshirt is a great all-round useful garment in lots of places. Also seemingly relevant--not from a need/dont need p[erspective, but becasue "most" tree stand hunters apparently dont deal with large wilderness areas, or frigid Northern weather.
4) Have you used an old dog leash to drag a decent-sized deer multiple miles involving mountains and stream/swamp crossings? People do it. But that doesnt make it the best way to do it. Again, see comment "most people dont deal with large...".
5) most importantly, the question was not about what is possible or common, it was about why the specific companies who exist solely to facilitate "hunting deep" utilizing tree stands (for example, lattitude as previously mentioned, ), dont also make apparel and packs that jive with that same ethos.
6) "overcomplicating things" is the whole point...sure, there's more deer in my backyard than there are where I described above. But I dont want to hunt there all the time. If choosing where to hunt becasue I like the environment and other factors that go along with that is "overcomplicating things", then yes, give me more overcomplication please. I have a deer in the freezer already, it's time to overcomplicate things!
The answer may simply be that "mobile hunting" as idealized and marketed, isnt common-enough in reality to make a viable market for those items. It seems as most people do it, hang-and-hunt just isnt common to begin with, and of those who do it very few are actually going far, makingthe idealized marketing aspiration more of a semi-ficititous thing that, while it certainly exists, isnt common enough to support a legitimate market. Thats where I'm landing, and this quoted post seems to reinforce that.
