Customer Reviews Arc'teryx Kyanite Baselayer Zip Neck

I wore this baselayer along with my Thorium down jacket, and a Gore tex shell when I snowboarded in the poconos this season. It was -20 degrees outside with high gusts of wind. I have iron anemia, and terrible blood circulation due to Reynaud's, but despite all that my core was warm. The arms were long enough to cover my wrists and the shoulders were stretchy enough to fit my athletic build. I highly recommend this product! I also like the small zip pocket on the bicep.

I love this base layer, its so warm and comfortable. Like wearing a big warm hug! Really helps me when working out on the croft in the cold wind, really great. I have 3 tops and the bottoms as well, wear them almost every day! Durable, easy drying. Really the best product I have ever bought and will definitely buy more.

So warm and comfortable. The cut and length are also really nice.

The best I have ever worn! Warm, comfortable. The fit is perfect.

Fit well, very comfortable. Great as a midlayer. Made a great Christmas gift.

This thermal shirt is great. The medium fit is perfect on me including sleeve length. (I am 5'8" and weigh 135.) I love the midnight frost color. The little zipper patch on the upper left arm is cool. The material is top quality. I'm going to wear this all winter long!

It's my second set, I don't want to wear anything else now! I've had the other set for about a year and unlike some of the comments , mine has no holes or fabric issues. I must say that I wash it in the regular cycle but I never put it in the dryer, just hang dry.

This baselayer is so warm and comfortable! I typically use it under a shell for most activities in the PNW, no puff needed! Best for easy hiking, XC skiing in cold conditions, or as a layer under a puff for camping or slow output activities in the cold. Looks great on its own as well!

Top 5 Arc'teryx products for sure. The 1/2 zip is cute and practical while being something that I can keep on all day. Super soft, super comfy, and a great baselayer in wet and dry conditions. My fave base layer for anything ski to climbing. Breathable and honestly stays unsmelly for more than a wear or two - which might be the most underrated base layer rating metric.

Beautifully soft, warm, and breathably comfortable.

Great color and excellent quality! Fit is fabulous, warm and fabulous all around! Arcteryx excels in quality, function and fashion!

Love it. Comfy and warm. Bought a medium and it fits well but sleeves are a tad long no biggie just cuff them or leave them down if it is cold. Love the higher neck another feature that keeps you warm. Easy care- wash and let dry on my drying rack.

This is a great heavy base layer. I wear it all the time for curling, and I really like the length, the fit, and that it has some stretch. However, the colours are atrocious. I have black and would purchase one or two more if there were good colours, but they've been so drab and just generally awful. Please come out with something bright/rich - labyrinth, vitality, expanse, etc.

Wish the sleeves were longer and had thumb holes! The shirt otherwise is awesome. Warm, wicks moisture and the medium is a great fit. I wear a 6-8 women.

I just purchased this in Midnight Frost. It seems thinner and is slightly longer than my older version in black, neither of which is a positive change in my opinion. I also really dislike the arm pocket, and particularly the contrasting black with the Midnight Frost colour. Please stop with the contrasting black trim - I would buy the Kyanite hoodie in Midnight Frost if it didn't have the contrasting black pockets. The Atom with black side panels is even worse.
