This is a piece of witchcraft! The hoody is superbly lightweight (I own a windproof that weighs more than this) yet offers microfleece warmth for very little bulk.
The fit is excellent. I'm 6’ tall with 38" ish chest and the medium is perfect with decent sleeve length and a warm hood that fits under a climbing lid well.
The reversible feature is less of a gimmick than I was expecting and I have found myself wearing the more breathable side outwards to shed heat when getting a pace on. I have spent all day in showery weather wearing the jacket and keeping nice and dry as it sheds water beautifully so I could keep the Goretex in the pack.
It is very lightweight so I have not worn it climbing as I'd hate to see grit tear it, but for walking it is now my go to jacket.
