    A bit on the small side for me, but Perhaps this is normal? I typical wear a 2XL shirt. I’d like to say that this is because of my broad shoulders and incredible physique. However, it’s because of that extra helping of lasagna or maybe an extra glass or two of wine. I do have broad shoulders, but if that was all I had, everything would fit much better in these.

    So these are tight around my belly. Since these are effectively long underwear, you’ll want them tight. In my case, it’s also motivation to cut down a bit on my belly size too. Currently, it is uncomfortably tight on me. Can I blame this on the stay at home order and the endless supply of fruit loops available?

    Great product and heavier than expected . Size runs one small. 230 pounds 6ft. with a 46 chest and the XL fits like a compression shirt.

    Fits great and with the zipper it's SO much easier to get on and off than the non-zipper (I also have) version. Not as thick as the last pair I ordered but still a good warm base layer. I would buy again.

    They are worth every penny, if you need to be in the cold for an extended period of time, this is money well spent. They laundry well, and will keep you comfortable in the extreme cold.

    I am a big fan of Under Armour clothes. I own Base 2.0, Base 3.0, BaseMap 2.5 and few other cold gears.
    I thought this 1/4 zip Base 4.0 be a perfect addition. Unfortunately it turned out to be too small (tight) overall. But, neck area was too big for my neck. I ended up returned it.

    Hey I bought the Under Armour Base and Pants Cold Gear 4.0.1 for a back packing trip in the Grand Canyon. They performed so well. I had temps in the 20's and didn't need much else on while at camp. Plus when hiking out and sweating, perfect moisture control

    Great fit, high level of warmth and comfort.

    The item was a little big but serve the purpose of keeping me warm while I rode the motorcycle at 44 to 54° did the job look good too
