Hugh D. (5/5)

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."

Great trekking Layer

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

John H. (5/5)

Best warm mid layer ever

"Since I have bought it in March I have almost worn it everyday until the warmer days. I have hiked in it the Alps, in the Cévennes in autonomy & done CrossFit with it outside in the cold and rain. The long zipper allows to regulate the temperature ideally. It was my first buy from the Kora brand and now I am totally in! I had several mid layers from arcteryx and Patagonia but this is my favorite."

Olivier c. (5/5)

Excellent clothing for a wide variety of temperatures

"For now I am living in Flagstaff, Arizona. It is late spring, and temperatures these past couple of weeks have ranged from freezing to over 80 degrees Fahrenheit. This sweater has quickly risen to my first choice first thing in the morning and in the early evening until I go to bed. I have never had a better mid-layer. It is very well made, from quality ingredients. I ordered Epidote Green and am very satisfied with the color. It feels like it is going to last for a long time. I hope to use this mid-layer on backpacking hikes during spring or fall, or when I hike in colder climates. Thank you for making such a great product!"

James L. (5/5)

Great sweater

"Used it for one 6 day trip in the back country so far and I really like it.It is nice to have something made of wool rather than fleece. The nylon lining that acts as a spacer to increase warmth and allow sweat to dissipate is a great addition to the item."

David J. (4/5)

Love it

"Absolutely love this jumper. Ski instructor in Switzerland I hardly took it off the whole winter . Not bulky under my jacket like other mid layers, very comfortable and breathable for cross country and warm enough for sitting on a terrace. Love the green colour."

Customer (5/5)

Excellent

"Perfect fit medium for me who is 173 cm and 75 kg. The sweater is warm but no too warm when you wandering. The only problem is that I will never take it off..."

Lars K. (5/5)

Great product

"I love this. Perfect with a vest on milder days or under a coat on cold ones. Fit is good (large at 6" 170#). Reason for only 4 star, order took 3 weeks to arrive and the tag is very scratchy to the point of being uncomfortable, but a seam ripper took care of it."
