Bought this in the Amazon sales, but I'd happily pay full price for it having worn it for a while.
In cool weather, this and a tech t-shirt are plenty for warmth. For cold weather, this works well as part of a layering system. Very warm despite being synthetic rather than down. Pretty good breathability - I've worn it under softshells and hardshells when on long walks on the North Downs Way, didn't ever feel clammy, but sometimes the warmth surprises you and you need less layers than expected.
For moderately active pursuits in cool or cold weather, this is a very good choice.
