Yikes! Just saw my Inca Trail countdown goes from months to days…Need to step up my preparation. The UA Base 4.0 cold gear have arrived, I tried them on and they fit! Although, I have to say, they are not as warm as I thought they would be for something that’s advertised as “built to take on even the most brutal cold”. I hope I am wrong and these will hold up at night. I don’t look forward to freezing in my sleep.
