>>2825254 (OP)>frost river packsNever heard of them. And I've spent hours searching the net for waxed or oiled packs back when i didn't know how to make them, so chances are that company is either highly local, or very recent. As I've seen that exact pack you posted from tons of chinese companies when I was living in Japan (called, among other things, "Deathkorps of Krieg marching pack" and "oilskin randoseru" - no clue if those offers are still up though), my guess would be that it's one of those short-lived chink brands, or an importer / reseller. Of course, it might also be a case of chinks copying.
However, looking at their website, the whole company seems suspicious - Their "care" instructions don't match traditional methods (shoe leather cream on backpack straps? seriously? That stuff is made to allow mirror polishing, not to maintain leather. There's a reason people use wax / oil mixtures for anything that isn't goretex), and their designs mostly seem to be based on modern bags made from synthetics, without considering the properties of waxed canvas at all. To name just the most obvious, those 90° corners will break the wax almost immediately, and get soaked through, unless they're reinforced with some sort of gum. On oldtime packs, there were wood reinforcements in such places, ot the packs were made with a rounded shape to begin with. Another thing is that the flaps are much narrower than on traditional packs, or even recent military bags. Overload them even slightly, or be in a storm, and the insides get wet. Neither is a mistake a legit "250 year old" company would make.
>classic-ish in waxed canvasDon't bother, good waxed canvas is almost unaffordable nowadays. Most of it is parafine soaked, or even PU-coated.
I'd suggest getting a regular canvas pack (cheap milrepro, for example - I'm using a highlander M37) and waxing it yourself. Either with beeswax (rub in, then melt with a heat gun or oven) or even better, a mix of wax and linseed oil.
