    OK but a design flaw

    a year ago
    This UA base is pretty thick for a base layer and does provide decent warmth. However, it fails in providing enough warmth in extreme cold especially when wind is involved. The problem with it is the neck and chest is sized disproportionally loose vs (zero compression) the rest of the areas on the body. In other words the loose areas on the neck and chest allows the cold to easily enter your core...I am no stranger to UA base layers I purchased my first 25 years ago the original cold gear which I still have, and recently purchased 3 more of the originals now they are re-offered after all these years...But this UA Base 4.0 fails far short of its intended purpose and price twice as much as the Original Cold gear...Not a fan of this offering.

    No, I do not recommend this product.

    Hi, Joe! We're glad to hear the base layer did provide some warmth, but we're sorry the fit and quality is different than what you are accustom to. We definitely understand your disappointment and appreciate your loyalty over the years, and also for you bringing this to our attention. I'll reach out shortly to discuss this further and I'd love to help you find something that may better suit your needs. Talk to you soon!

    High quality, extremely warm.

    If you need a high-performance base layer for extreme cold, the UA Base 4.0 ¼ Zip is one of the best options out there. Just bought my second one.

    Yes, I recommend this product.

    Best UA Base Yet

    a year ago
    I've been a long time user of UA Base. This new technology is absolutely the best yet. Haven't gotten into really frigid temps yet but in High 20's and low 30's it was more than adequate.

    Yes, I recommend this product.

    Like the overall fit & feel

    a year ago
    Purchased a Large. The fit & feel is nice. Only issue is it maybe a little too tight in forearms (if you like to roll-up your sleeves).

    Yes, I recommend this product.
