Columbia's warmest for Winter's coldest.

Reach for the Columbia Men's Heavyweight II Half-Zip Top Baselayer when winter's temps are at its lowest and you're still craving a ski session. Omni-Wick manages moisture if you start sweating in this heavyweight baselayer. Columbia added an odor-resistant treatment and an Omni-Heat thermal reflective lining for a surprising boost in toastiness.

Lightweight warmth

    Good looking, lightweight warmth, great for layering or as a top during active adventures. My only complaint is that i have an “athletic” build so it is a bit tight in the chest. I ordered a large but the chest feels like a medium. Not awful but you should be aware.

    VERY Disappointed

    • Familiarity: I've used it once or twice and have initial impressions

    This wasn't a cheap shirt. It has been washed no more than 3 times on the delicate cycle and has pulls ALL over it. It is so disappointing that a brand we love is performing so poorly. Feels like a total waste.

    Very Pleased

    • Fit: True to size
    • Size Bought: xl

    Wow, terrific piece of equipment - just tried it tonight, no mid layer, just this baselayer and a Columbia coat - 30 deg F out and windy. Very toasty.
    It got really delivered quickly - good since Im going to Reykjavik this Monday.

    Perfect Under Jacket item

    • Familiarity: I've used it several times
    • Fit: True to size

    My brother has this jacket and it is the perfect thickness to wear under winter coats. It really helps keep the warmth of your body on a cold day. I recommend this to people living in colder temps.

    Great fit

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size
    • Size Bought: Medium

    Great as a base layer, and a great fit as well. It fits longer in the torso, so it won't ride up on you and/or allow you to tuck it in if need be. I'm 6'0, and 175lbs, and the medium is perfect

    So warm!

    • Fit: True to size

    I got this as a gift for my boyfriend who does ski patrol in Park City. He loves it and and says he has never been warmer at work! It fits true to size and is surprisingly long in the torso. He's 6'5 230lbs and the XL worked out great. He recommends it for anyone looking for a warm base layer

    What is the weight on large size?
