I have one I got from Cabellas years ago in bargain deal,cheap.Henley style olive green,use it layering.15 yrs old
The other one for winter is a thick ragg wool,white/brown/gray my dad left me, Eddie Bauer.30+ yrs old. Excellent in snow. Both where made in US. I would check out used clothing stores for quality ones cheep. Love wool. Look for English,Irish and New Zealand stuff too.
