Well, unfortunately, summer has come

"Well, unfortunately, summer has come with these use. However, they sure are comfortable. I tried them on and I look forward to wearing them when the weather turns chilly again."

Warm, excellent fit. I like

"Warm, excellent fit. I like the wrist covering capability on very cold days"

Yak wool is like Spinal

"Yak wool is like Spinal Tap's version of amps, it goes to 11 when others can only go to 10."

The best most comfortable sweater

"The best most comfortable sweater you will ever wear in all weather conditions. Bought this sweater 10+ yrs ago and just replaced it with the exact same model. Still perfect."

Beautifully made, soft and comfortable

"Beautifully made, soft and comfortable and very warm, I love it! The only complaint I can think of is the length - whilst I am quite tall, it only reaches the top of my butt (which is fine whilst I'm standing but will leave the lower section of my lower back exposed when I'm sitting or bending over. But only a slight problem and certainly wouldn't buy me from buying the garment again given how light but warm it is. Kora also added a very nice touch with a personal hand written note which also told me when my next garment would be arriving as I had ordered another Kora Yak/merino top. I thought that was very considerate."

Great Travel Sweater

"Totally agree with other reviews calling it the best sweater. I have three, plus one for my wife. It was essentially the only top I wore for three weeks in a cold, damp Ireland (is there any other kind?) in OCT/NOV 2023. Wore it over a merino wool t-shirt and under a Patagonia Torrentshell rain jacket in rain and/or high winds and was comfortable the entire time. It adapted readily to changes in temperature, weather and activity. Probably the ideal top for a range of conditions in cool weather travel. Pricey, but given you can replace several other tops with one, well worth the cost."

Carl C. (5/5)

Great trekking Layer

"Warm, breathable, attractive, and very comfortable…my second buy of this world-class quality layer"

High quality garments. A bit

"High quality garments. A bit spendy though."

Xenolith sweater

"My third Kora product. Best sweater I've had. Ultra soft feel, light, very warm. I have the purple version and I get lots of great comments from ski instructor friends asking about it and the company."

Marc L. (5/5)

Simply Amazing!!

"The Xenolith represents the pinnacle of both softness and warmth in a midlayer. The yak and merino combination creates a luxurious feel that will make pretty much anyone more huggable. Performance wise, it’s proven to be warm, breathable, and durable so far. I tend to wear it over a light or mid weight base layer, although it’s soft enough to be worn alone. The deep zip and mesh lining add to its technical chops, as does the Polartec Alpha. If there’s any quibble, it’s that the sleeves could be a tad shorter, but obviously that issue will vary depending on one’s height/arm length. I do wish Kora would make a hooded version and add a few brighter colors. As for the current Xenolith, they have a real winner that I highly recommend."
