The Henry performs excellently. I have worn it in dry weather over a simple cotton T-shirt at freezing with no concerns and in snow storms with a Gore-Tex outer shell down to -8C and can confirm that it was a thoroughly pleasant experience. It does have a few bad points for me, The hood is too big, probably so it can accommodate a climbing helmet, this leads to the hood synch cords being a lot longer than is really needed and managing the hood can be a chore, especially if you are wearing it as mid layer since it is a lot larger than the hood on my Berghaus shell. Types of weather you will be camping in – Camping in the winter? You will need something warm for when the temperature drops. Summer camper, you may just need to take a lightweight waterproof in case you get caught out. It also suffered with the fairly typical loss of the odd piece of down at the seems in it's first few days as well. Nothing unusual there.
