Overview
 

Continuing the Base Crew Tops line, Under Armour has introduced the Base 4.0 Crew Mens Long Underwear Top. Bold and incredibly warm and insulated, the moment you put on this top you'll feel instant comfort and coziness in the coldest conditions. Designed with Flatlock Seams to prevent chafing as well as Strategically Placed Ergonomic Seams and Raglan Sleeve Construction you'll have a smooth feel against your skin and total mobility while eliminating shoulder seam abrasion points. This crew top has ArmourBlock which neutralizes the microbes that cause odor before there is any odor at all. The result: moisture transport with maximum scent suppression. Outfitted with ColdGear Fabrics, a double-sided fabric that wicks moisture from the skin and circulates body heat, you'll stay warm, dry, and comfortable without being weighed down when you wear the Under Armour Base 4.0 Crew Top. Excellent as an extra layer under your ski clothes or when jogging in cooler conditions, get one today and feel the comfort you've been missing.

I purchased this baselayer as an extreme cold weather option. I found that it keeps me very warm, too warm for days over 28 degrees, but works great below that. It does fit a little smaller than I expected and did go up a size.

A: Eric, I pulled some data right from the hands of the UA experts over at UnderArmour.com - looks like the numbers directly reflect the warmth of the layer. Starting at 1 and going to the max at 4. From Under Armour: "1.0: Cool conditions/Intense activity, 2.0: Cold conditions/Moderate activity, 3.0: Extreme cold/Intermittent activity, 4.0: Made for the most brutal cold around"
