Absolutely LOVE these tops. Have always had problems finding tops with longer cuts. These are fabulous! Non-itchy, warm, lightweight, wicking, smooth. First time I tried one, I said I would never go back to synthetics.

    Love this shirt as super light base layer. It's very well made but not as soft as most of my Icebreaker pieces but once it's on you don't even know it's there except for the extra bit of warmth it provides. Warm and no bulk - winner! This is a slim fit piece. I wear M-L in Icebreaker depending on the fit style. I don't like things to be really clingy - I went with a large for this shirt. It doesn't cling to my body but fits close and just skims over my curves.

    I bought a variety of merino wool items from different makers (Smartwool sweater, Ibex tank top, Smartwool and Darn Tough socks, and Icebreaker long underwear and the Siren top) for a 12-day trip abroad where I wanted to pack extremely light. The Siren top was by far my favorite of all the items I purchased -- it is soft, flattering (ideal length in the sleeves and body for me), and stayed odor-free for the entirety of my trip, even after being worn every day! I hung it up at night to air out and imagine it would dry quickly if you needed to wash it out in a sink during your travels. Highly recommended!

    Love the pink color, true to the size chart and very fitted. Was thinner than I was looking for, so think of this more as a true underwear layer.

    The version of this shirt that arrived had short sleeves, despite the description on the www site saying it has long sleeves. So, I sent it back.

    I like this top. It is very very thin and warm. The quality is great and it is merino wool. I have to order another size, smaller. The one I ordered is big for a medium size. (long sleeves and body)

About Icebreaker

Crafted using only the finest merino wool grown in New Zealand’s Southern Alps, Icebreaker clothing is known around the globe for its incredible comfort and performance. Unlike synthetic fabrics developed in a lab, Icebreaker merino wool is grown, cultivated and field-tested in the mountains. Designed to offer exceptional comfort during a range of outdoor sports, Icebreaker underwear and apparel naturally resists odors, regulates body temperature, wicks moisture and dries quickly. Superfine New Zealand merino wool is also much softer than traditional sheep’s wool, which means no itch. Icebreaker socks, long underwear and base layers also come in a selection of weights to keep you warm without overheating. Ready to join the merino revolution?
