I use this jacket more than any other jacket that I own and after trashing one (rubbed it raw scrambling through slot canyons) I immediately purchased a second one.
My first Driclime Ether lasted a couple years and was worn as a casual jacket, insulation layer, and as a wind shirt.
With a thin wool layer underneath, it becomes much more versatile than most jackets. It breathes extremely well and has a soft lining. Wind is hard pressed to cut through and is easily kept at bay.
The only downside I have found is that it is extrememly annoying to wear over long sleeved dress shirts or flannel shirts. The nice soft lining in the sleeves does not move freely against these types of shirts and putting it over them is frustrating. Once adjusted over obnoxious casual clothing, the jacket fits like a second skin.
Arms are cut nicely and do not lift the bottom of the jacket when your hands reach over your head.
I’ve worn it as the insulating layer with a thin base layer and shell in near 0 degree temps with mild aerobic activity and it kept me warm without overheating.
5’11” 180lbs 42”chest - L fits comfortably and allows layering underneath.
