I used a thick wool sweater that my mother knit for me in 1952 for nearly 20 years, much of it in the Sierra. It was knit from fairly loose-spun, large diameter yarn. My records show it at about 19 oz. I used it through the 70’s as part of my then primitive layering system of a long-John shirt, sweater and parka. It finally wore-out/unraveled. I then used a repurposed cashmere sweater for several years together with a Pendleton wool shirt in cool, wet country (mostly in the North Cascades) and then finally switched over to Capilene or Merino, fleece, and down or synthetic puffy. My wool pants were army surplus.
I was rarely cold in my wool clothing nor have I suffered in my base-layer, fleece, down coat and parka. The wool was nearly twice as heavy and bulkier though.
As Aimless mentioned, you may want to learn to sew: and knit.
