Soft, warm, and comfortable
Fell in love with SmartWool with this purchase. I like the red colour on my medium brown skin. Very flattering shape, it's long, and stretches enough without being too loose.
Chaud et confortable
Je suis fan de la laine mérinos car elle est à la fois chaude tout en étant respirante. J’aime bien porter ce chandail tant en salle d’exercices qu’à l’extérieur. Sans compter que j’aime bien la couleur…
Very cosy
This shirt is very comfortable and flattering. Great for yoga because it doesn’t slide.
Il est parfait!

Well made, quality product
Smartwool’s merino top is perfect if you want a wool top without the bulk. This top is typically a fitted base layer, but by sizing up, it can be a regular wool top. Quality is what you expect from Smartwool. There is no pilling and maintains its colour after wash. I have a 106cm chest and XL is a prefect fit.

Smartwool Forever
I was first introduced to the Smartwool base layers 18 years ago and the product remains outstanding. They are so soft and cozy you never want to take them off. The colour is lovely in person and a departure from my basic black. The sleeves and body are a good length even for me at 5’10”. They are expensive but excellent value with my original layers last over 15 years.

Worn - Returned
This item was a return from someone else. It had their hair all over the piece. They just folded it up back in the box and returned it.
Size Issues
The colours are very beautiful and it feels like silk. But, the sleeves are forever long and the fit extremely fitted. In the past, I have consistently ordered tops size M, fitted style. This particular top though seems to be made for tall, lanky people. The already overly long sleeves make sizing up for a more comfortable fit impossible for me. Also, there is a small strip of 5 colours (the same colours as on the packaging of the top) that do not match those of the top itself permanently attached near the bottom of one of the sleeves. To me this would be an irritant every time I look at my arm. So, very sadly, I have decided to return this top.
Confortable et chaud
Taille parfaitement. Je l’adore!
