I am a heavy equipment field mechanic…. Not an athlete…. I work outside all day, for long periods of time… I have tired several different types of base layers to stay warm, I have had under armor in the past, and was thrilled with how it worked. But tried to find a cheaper option…. Believe me when I say that was a waste of time, and overall a waste of money.. nothing compares to these compression cold gear base layers that under armor makes . Top of the line , best of the best, just like the brand of equipment that I represent , Caterpillar .

What does the hem look like? I have an older UA Coldgear Mock Turtleneck that has a rubber/elastic grip at the hem so it doesn’t ride up. It is phenomenal!

We apologize, the Men's ColdGear® Compression Mock does not feature an elastic or silicon material within the hem.

I wanted to buy a long sleeve mock neck base level three shirt. I could not see anywhere where I could pick my base level. . Why is it so hard to find out what base level shirt you are ordering.
