What I wanted and more

I bought this for a backcountry skiing when it’s a little wet or windy. I run very hot when touring so I found shells get too swampy. This has totally changed my layering system. I’m using it above my base layer and it stays on most of the day. I’ll even put it over my micro puffy on the way down on nice days and have been leaving my shell a lot of the time. The hood fits really well under a helmet to keep you warm when needed without being floppy or needing adjusting. It wicks and breaths really well but has enough wind and water resistance to avoid needing to stop and relayer unless it gets more than moderately wet. It weighs nothing and packs down to nothing you can literally put it in your leg pocket if you wanted to. The only downside is it does get smelly pretty fast so needs more washing than most of my other outdoor gear but so far it hasn’t lost a lot of water repellency using high quality outdoor detergents. Also great for running.

I have gone on a couple runs in the wind and light rain. I like how light and breathable it is yet keeps me warm and dry enough while running.

Jack of all trades

I just sweat a lot, so this is the perfect soft layer for hikes with a full sleeve as base layer. It also comes in handy for multiple little situations and packs super small.

Great Running Wind Shirt

This has been one of my favorite running wind shirts so far. It has kept me surprisingly warm on winter runs with only a mid to heavyweight base layer under (25-40F). Fit is slightly baggier than I would prefer for running, but makes it easy to layer (bought size L, I'm 6'1" ~185lbs). Can't comment on the hood yet since I haven't had to use it.

A-, but a quality windbreaker.

Good jacket that could be great, if it only had pit perforations. It does breath well and blocks wind well, so the jacket is very good. That said, I get a little clammy in the pits when working in the yard in low 50’s

Perfect jacket to roll up and toss into a pack ‘just in case’.

The Kor AirShell is the perfect jacket to roll up and toss into a pack on those iffy days when you’re not sure if the skies will open or not. While not a hard shell, it does a great job of holding off the rain until you can seek shelter under a tarp.

Great addition to the fleet!

I’ve been looking for something like this for a while, I opted for the newer version with some water proofing which is a huge plus. This jacket does its job as a windbreaker and actually breathes! No more being soaked in the first 5 minutes of a run.
