Yeah - pretty pleased with it - it's a bit stiff so glad I did not get the jacket. I like the fact it is long both top and bottom as really keeps my neck and upper shoulders warm and goes below my shortie jacket.
Not having a cable is a treat - battery seems to last a good bit and the vest is warm on its own but I would tend to advise leaving it on low so your core heat does not drop in the first place.
Has not been cool enough to really test.
On the first ride I realized after the ride it was on high the whole way....pretty toastie.
Was clear from a couple rides with my set up it's my back, neck and shoulders getting cold from back pressure from the "wall" up front.
Since those areas get stiff riding anyways this is a real treat.
Careful with the size as it's a slim fit so a size up might be wise. There is no give in it.
