As stated above KOM has two different weights of wool gear. The lighter weight would be more suitable for the weather in Texas or other parts of the Southwest unless that extreme cold front is passing through. I layer my KOM heavy vest with a Pendleton wool shirt and perhaps a set of moisture wicking undergarments and I'm off to the bowhunting races. Course I would also add a good pair of Johnson wool pants to the mix. It ain't cheap but it is not as expensive as 100% KOM or Sleeping Indian.
