Kor Air-shell Jacket Doing What It Is Supposed To

So far so good. I have worn it in cold weather as a layer garment over a base layer for walking and hiking. (I put an insulation layer over that....) Something like 10 times as of now. It is doing what I planned. It packs down very small and along with that, is very light. In such a layering configuration as I described, 20+ mph winds and 25 degree F did not bother me.

Awesome Jacket

I was hoping that this jacket was going to be a wind layer for me while playing golf and it has worked out really well. It is NOT wind proof but it does stop a lot of the wind, and it is breathable so it will not be like wearing a trash bag. The jacket is super light and you can not really feel it while it is on and it does not really make a lot of sound either when you move. When you are not wearing it, it can pack down into a very small size so this thing tics a lot of boxes. It is one of those jackets where you keep thinking of ways you can use it, rather than intending a jacket for something and figuring out that you can not use it for this or that, I am thrilled with this one - an amazing layering piece or as the outer shell.

The best

This is my third airshell from MH and it won’t be my last. First without hood and it’s great for running and I don’t live as cold of a climate now so I don’t need the hood for 90% of my runs and hikes. These things are the best and I have put them through everything.

Very lightweight

Very lightweight and just enough to not need a puff jacket.

Perfectly Utilitarian

There's a reason you see so many really favorable reviews of this jacket. It checks all the boxes. Packable, super light, blocks the wind, repels mist or light rain and looks great. Pull it out of your kit at a windy summit or the top of a pitch. If you are slim and athletic, it fits true to your usual size. I have a paunchy "dad bod", so I had to go up one size for midriff room. You won't have to, though. I also have the lined hoody version of this garment, and like it equally for belaying or just spectating at the base of the crag.

Color in accurate

I purchased color "moon moss" and it seems like more like yellow on the website but actual product is more so light green. They need to color accurate the product on their website.

Perfect ascent shell to dump heat while breaking wind. I wear this over a 250gram smartwool baselayer while ascending mountains in 25-45 degree weather.

Love it!

Huge fan! Perfect arid desert wind, mountain biking, submitting, or wearing to work. Blocks wind and is actually breathable. Easily packs down super small. Looks great. Fit perfect. Very happy with purchase. It's not water proof at all, though. Don't expect that.
