Most Comfortable Sweater Ever
Iv owned two of these now and I love them. You can wear them all the time because the fabric breathes and allows airflow even when you go into warmer indoors. This can mean the sweater is a bit cold in windy situations but just wear a base layer underneath and its perfect for cold mornings. Most versatile sweater iv ever worn. Im usually a large (5' 11" 170) but if i wear a medium because i dont like my jackets to be baggy. The sleeves fit great and waist line is right below the belt. I will wear this sweater as long as they keep making it. Wish they had more colors though. Arcteryx did it again

Excellent sweater
My wife bought this sweater for herself (176cm tall / 5'9"). Fortunately for me it was too large for her, but fits me perfectly (182cm /5'11"). It is my favourite sweater and I wear it all the time in the winter season. It is durable and very comfortable. I would recommend it to anyone, but beware that it is quite large.

Better than fleece.
Bought two of these for my husband because we both love the design and quality of Arc'teryx products. His initial response was to return them because he didn't need any more fleeces. (He probably has more than 40.) I talked him into keeping them saying that they were more like fleece/sweater hybrids. But more importantly, they are more stylish, comfortable, and warmer. He figured these things out the first time he wore them. They are now his "favorites". He looks so much sharper in these sweaters than his "slouchy-looking" fleeces. It does have a trim, athletic fit. So if you like roominess, order up. My only complaint is that the knit does tend to pill. But that wouldn't stop me from buying more.

Warm and comfy one
This Arc'teryx item is absolutely warm in the winter, and it 's so stylish, its materials 'Polartec Thermal Pro' is so comfy, I love this .
