Picked up a couple middish weight base layer tops at Costco yesterday. Half merino wool and half “Primaloft” poly. I think they were about $18 per?
Anyway, just passing it on. They have merino blend stuff most years, usually different labels on them. This year it’s Karbon.
I like the blend, they perform quite well for my use, and I’m not paying 3x the price for a company add campaign.
