Wool is wool. The important part is the way it's made and if you can wash it. If it's dry clean only and you get it soaked a few times, it will shrink. If you wash your dry clean only garments then be prepared for it to shrink and to loose fibers making it thinner and thinner over time. There are bargains. I bought OD green US military dress wool pants for $7 each in the plastic. Worn them for the last 10 years and they will likely be a good bargain at the yard sale when I'm gone. They're good for midrange weather. I wear Pendelton shirts everyday, work or play. They generally wash well. Only had one Pendelton shrink. Bought a Cabelas woodsman coat in the bargain cave for $115. It's as heavy and durable as a $385 Filson and it's washable. However,
When it's cold and I plan to be out day after day, I wear KOM head to toe, Smartwool inner, and a windproof wool sweater. This past September I camped three weeks on the Haul Road with temperatures down to the low teens and up to the 40's. It was windy, rainy, snowy, and sunny. I tried every thing I owned. My silk, poly, fleece, and cheap wool failed. I was noticably more comfortable with the Smartwool and KOM in a much broader range of temperatures and conditions. Bite the bullet and get quality stuff.
Howdy Jeff.
