This T-shirt is one of the reasons I love Icebreaker so much. It's extremely comfortable, it fits perfectly (I'm a lanky 6' 5" & 220 lbs - I wear an XL), and you can wear it for 4 or 5 days straight without a hint of B.O. I returned a couple Icebreaker daily wear shirt for one Oasis shirt because t... Read More

    Make sure and read the size chart. I always wear a large but checked the chart and XL is what it said to get. The XL fits beautifully. Very well made and comfortable even on a hot day. Great product as always from IceBreaker.

    My wife and kids now think I have an unhealthy addiction to merino wool. I've bought so many merino wool items recently from STP for myself and the family as well. These Icebreaker shirts are simply excellent! It amazes me that so much warmth can be retained in such a small amount of material, but on he same hand seem to never make you hot......more like a body temp regulator instead of something strictly for warmth.

    The other amazing feature of merino wool is the no odor, and believe me I've put that to the test. I work from home and can go days without seeing anyone but my family. I typically just put on one of my IB shirts and then another shirt on top. I've gone almost a week in the same IB shirt and there is no stink, not exaggerating.

    Like all the IB items I own, these shirts are well made and good quality. I've got some other IB short and long sleeve base layer shirts which seem a little looser than this shirt even though sized the same. I am sure this shirt is designed to fit differently, hence it having a different name. This shirt is not nearly as snug as the IB Anatomica, which I returned because I wanted something a little less snug. This shirt's material also seems just slightly thicker than my 200 base layer IB shirts.

    Highly recommend!!

    I bought these for use in the summer as they are short sleeve shirts and I didn't see any information on the weight of the wool. Theses are IB's number 200 weight. Not what I thought they were. As always, IB produces high quality clothing so I'll find some use for them. Just disappointed.

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?
