    I live in Icebreaker base layers 9 months a year. I live in a ski town and the warmth, breathability and skin feel is the best!!

    Warm, stretchy, comfortable, and moisture wicking. Used 4 days straight on ski adventure and it didn’t stink! Love this thing.

    Exactly what I wanted. I wear this on days that have temps ranging from 40 F to 65 F , and I never feel cold or hot. Minimal odor retention , great fit. I will be buying more. No complaints. Great price. Great for everyone, from beginner to expert. Cold to hot, this is the top for you and the whole family. I will be buying other models from Icebreaker! Minimal sweating and stank, what else could you ask for?

    I’m a nurse and my department is so cold. The cut of this shirt and the warmth of merino make it a perfect shirt for winter work days

    Yes, I recommend this product.

    Very flattering and feminine cut. It's great at wicking moisture and drying quickly. It's versatile - I use it both as a base layer under sweaters and as a stand-alone piece. I usually wear a small and it does fit but is very snug. I would probably size up to a medium if I had it to do over.

    Love it! Please make in larger sizes!

    I have several of these, and love the fabric, and deep neckline. I wear them under sweaters in winter, and sometimes on their own in spring and fall. However, I can only wear them when I'm extra thin. I have broad shoulders, muscular arms, and a substantial bust, and much of the time, the XL is too tight. I see that you're making a few items in larger sizes. Please make this one in sizes larger than XL! I would live in it! Thank you. P.S. Also, please make the Siren Cami in larger sizes. Such a useful piece.

    Yes, I recommend this product.
