Here is what George Sears has to say on the subject of clothing...
"As to clothing for the woods, a good deal of nonsense has been written about "strong, coarse woolen clothes." You do not want coarse woolen clothes. Fine woolen cassimere of medium thickness for coat, vest and pantaloons, with no cotton lining. Color, slate gray or dead-leaf (either is good). Two soft, thick woolen shirts; two pairs of fine, but substantial, woolen drawers; two pairs of strong woolen socks or stockings; these are what you need, and all you need in the way of clothing for the woods, excepting hat and boots, or gaiters. Boots are best--providing you do not let yourself be inveigled into wearing a pair of long-legged heavy boots with thick soles, as has been often advised by writers who knew no better. Heavy, long-legged boots are a weary, tiresome incumbrance on a hard tramp through rough woods. Even moccasins are better."
Things to take...
Coat, pants and vest of fine cassimere
Soft, thick, woolen shirts
fine, substantial woolen drawers
strong woolen socks
I have highlighted the adjectives in the above list. None say cheap or modest. To my minds ear I hear sturdy comfortable gear that is not an incumberance. That says not cheap, even today.
Now things not to take...
Coarse, heavy, tiresome weary, incumberance. These are the adjectives that speak of poor gear- even today.
Add to the gear a custom hatchet that cost 3 days wages and you have a kit that is by no means modest or "old timey" (at least for the day).
People inevitably misinterpret the meaning of traditional, or what the "traditions" of our forefathers were. We are a species of inovators...
Match lock gave way to wheel lock, which gave way to flint lock, that to the percussion lock, and that to the self contained cartridge. Single shots gave way to repeaters. Smooth bores gave way to rifling. Despotism gave way for constitutional monarchy, gave way to representative government. Heavy smelly wool gave way to light synthetic fleece. Heavy gives way to light. Coarse gives way to fine. Oppressive gives way for somewhat less oppressive...
And, just a note on the "Even mocassins are better." That is not an endorsement, but saying that a foot covering that provides no support and minimal protection is better than one that is a heavy, weary, tiresome incumberance.
If your great grandfather was hear today he would slap the flint lock out of your hand and burn it on a pyre built from a moth eaten wool blanket and an oilcloth rucksack if he could get his hands on the gear we have today at the [relative] prices we have today.
