カイヤナイト ライトウェイト ジャケット メンズ

Very comfortable. It's light, stretchy, soft inside and out. I bought it mainly for running when it's in the 40s, also wore it in the 50s to walk the dogs and it was a nice layer. Good value compared to other jackets and quarter zips of similar weight.

The jacket is extremely comfortable and very lightweight. Size S weighs 273g, size M weighs 283g. The zippers are extremely smooth and made by YKK. Despite the fabric being elastic, there are no wavy zippers (wavy zippers can appear on some full-zip hoodies when the zipper is too long, or when the fabric shrinks). The outer surface is smooth and does not collect lint and does not appear to pill. The two outside pockets have zippers. The jacket is extremely stylish and just looks really great. The only disappointment I had was that there are no pockets on the inside. On most jackets / hoodies there are inner non-zipper pockets on the inside - these are very easy to add because there is already extra fabric used to make the outer pockets. But not on Kyanite, and I think this is a missed opportunity. If it had the inner pockets, I would literally be completely out of ideas on how to make this product any better. It is that close to perfection. I did test two colors - "black" and "black sapphire". The black is definitely more versatile and it just works with anything. The black Kyanite is the ultimate universal jacket that you can wear at pretty much any occasion with any wardrobe and it will always look great. The black sapphire is also a wonderful color and when you match it with some white-ish or milk colors, it is incredibly beautiful and looks even better than pure black. But it is not as versatile and doesn't look so great with jeans for example. So, black sapphire looks better (and definitely more stylish) than black when you find a good color match, but there are fewer good color matches. I would have loved to own both but if I can choose only one, it would be the black one. I attached some photos showing black vs black sapphire, but do note the black sapphire is pretty much impossible to photograph accurately, because it depends on the ambient lighting so much. Regardless, black sapphire is a mixture of black and navy blue and with some additional factor that I cannot identify. You really need to see it in real life and in various lighting conditions including direct sunlight. One last point I wanted to make - I ordered both jackets in size S. However, one was 10g lighter than the other, and 1.5cm tighter. It was enough of a difference to make one feel too tight while the other one felt perfect. So there are definitely some QC issues because I would not have expected so much variability within a single size class.

I bought one of these in black and beige, they are the perfect spring/fall jacket for temperatures below 20degrees celsius I wear them everyday aorund town, at home, and in the office. Haven't managed to test it for sports since I think it's already too warm where I live but I can imagine it is a very nice layer to have in the winter. I usually love wearing turtlenecks and this jacket feels just like one with the high collar, with the added benefit that it can be unzipped.

In preparation for next winter, I got the Kyanite LW Jacket, which does not have a hoodie. I prefer ski clothing without hoodies, as these are non functional when consistently wearing a helmet. I shall it use as my mid-layer under my hard shell Arcteryx jacket and over an Oslo first layer. In general the cold does not truly affect me, whereas I ski at least 80 days per season. I most certainly love the return to the past grey blueish coloring as the understatement is much more of interest than dysfunctional fashionable colors.
