Review: I love it - Love it. I took the plunge in a Merino.tech t-shirt last summer and I love it. I got this in the winter, mainly for when I'm on my motorbike. It's a top quality item. Very comfortable and warm. When worn over another merino top it's a great combination. I'm sold on merino - it is worth the cost. This is now my go-to brand for all my merino clothing. Oh, you sometimes get free merino socks too. They are also very nice on a motorbike in winter...
Review: Wears and washes well. - A quality product! I have purchased these for my husband (6'5") on multiple occasions, they wear and wash well (we hang dry to avoid shrinkage). Have also gifted to family who also enjoy this. Very warm but not heavy, breathable and look great on it's own, but my husband typically wears as a base layer for work or for winter sport.
