    Versatile moisture management.

    Some folks take it easy when they head to hill, but you trench out sweat-inducing turns each and every run of the day. That fact makes it all the more necessary to suit up in the Under Armour Men's Base 2.0 1/4-Zip Top before starting your day. This mid-weight top is light enough for spring slush yet supplies enough warmth when it's layered under a warm jacket on chilly January powder days, and the 1/4-zip front provides instant ventilation when you really turn up the intensity.

    The snug-fitting four-way stretch polyester accommodates every move you make, absorbs sweat, and dries quickly so you don't experience chills while you're riding the lift. Flatlock seams and raglan sleeves ensure chafe-free comfort, and the Armourblock anti-odor technology keeps you smelling fresh for the bar scene at the end of the day.

    The Best Thing Going...

    I have been using various Merino Wool and synthetic base layers for years. I believe UA found the right combination with this piece.

    The fit is great. Just enough stretch to allow you great freedom of movement, but not so tight that feel constricted in any way.

    I took two of these for an 8 day ski trip to Canada, and wore them on alternating days. There was no odor, and they retained their shape well. These provide just enough insulation when worn beneath a 60g insulated jacket.

    I do prefer the 1/4 zip to a crew top, as they seem to lock out the cold a bit more. After 40+ days, these sill look and function great.

    I have yet to try a merino wool base layer but I imagine this is the next best thing. Given the price, it's amazing. Highly recommended. I use just this and a slightly insulated jacket for almost all conditions on Mammoth Mountain, CA. If you are sensitive to cold, you may want to look at the 3.0. Best thing about this product is how it deals with odor. I also like the zippered version because I do run hot and it's a big relief to be able to zip it down when I sit down for a brew.

    This top layer is wonderful. I was hesitant at first to buy the zippered version but have since been extremely grateful. Zipper is protected from your skin by a small layer so the cold metal doesn't cause any irritation at all. A little thicker (some kind of padding almost) than my other under armour shirts. Almost went with the 3.0 because I stand outside a lot during the winter due to one of my jobs. Very glad I didn't. I am almost too warm in this 2.0 sometimes. I run slightly hot though. Standing around in this and a polo down to 20 degrees and I felt comfortable. Does a decent job of wicking moisture except in the back when I was working and moving around a whole lot. But under normal conditions, it was perfect. Definitely helps keep the stench of sweat at bay, until about the third day. Then I recommend washing it, lol. I am going to order another of these and maybe even the 1.0 for warmer circumstances. Love this stuff!

    Great mid-weight base

      The 2.0 1/4 Zip is often my go to base for hiking in cool weather. Comfortable against the skin, dries very quickly. Always appreciate the zipper to vent as I get too warm. Often pair with my Marmot soft shell for cool windy days. There are superior materials out there, but for the price...
