no vents, zippers leak air
nice coat, haven't worn it below 19degrees yet, but warm at that temp with just long sleeve on.
comfy fit, a little room for 2nd layer. and length is perfect for strapping in (no cold air up your back), but not too long that it's constricting.
zippers, both front and for zip-off sleeves let air in.
no vents (even tho tag says mesh lined vents)
not many pockets
