*by F***A on 2 February 2026*

Extremely disappointed. I purchased these for winter weather based on the overwhelmingly positive reviews, but after finally trying them, I feel like I completely wasted my money. It’s only 55 degrees Fahrenheit today and my legs are freezing. When I compare them to my $11 cotton and polyester long johns, there’s no contest. The cheaper pair keeps me significantly warmer than the $100 plus merino wool base layer from Smartwool. I’m genuinely shocked at how poorly they perform given the price and reputation.
