John,
can you explain what you consider cold and what kind of conditions you plan to wear that?
I have some of the Asbell wool as well, but this is essentially blanket wool.
That is 100% different from a Loden wool fabric.
Especially now, they are producing all kind of specialized Loden garments.
Loden is a walked wool fabric. You would call it felted, but in a consistent manner.
Also, the conditions in what you hunt in should also determine your fabric choice:
Are there a lot of burrs or thorny stuff in your neck of the woods where you hunt?
As an example, where I hunt, there is a lot of sticker burrs and a lot of thorny stuff, so outerwear made from fleece or higher nap wool is an absolute no-wear (unless you like to pick sticker burrs for hours, lol).
What I like for pretty cold is:
Merino Icebreaker long underwear
Depending on the temperatures, a thin, medium or thicker fleece shirt/jacket a windbreaker vest if it is slightly windy or a Cabelas MT50 Gore-Tex jacket and overpants when it is "very windy and humid".
If there is no wind, only a thinner wool shirt over the underwear, German army pants and a poly-cotton overjacket. The overjacket will not pick up sticker burrs and protects the higher quality clothing underneath from thorn damage. It has pockets for all the gear I want closeby and is stick and limbs camo made in the USA.
