I love this jacket! It's really warm and comfortable, and it looks great! As far as warmth goes, I'd say it's a medium to cold day jacket, because it's well insulated, but if you want to wear it in the spring it has large vents on the sides that make it really versatile.
There are also lots of pockets in the inside and out, and it has super comfortable hand gaiters which are a great feature.
I have the Calypso Coral coloured one, and found the colour to look slightly brighter than it does on the website. I actually like it better in person than I did on my computer screen. Also, do note that if you're buying it online, I usually wear medium outerwear (I'm about 5'7), but found the medium in this jacket to be a little bigger than I would have liked. I exchanged it for a small and it fits perfectly! The small is slimmer but not much shorter than the medium, so if you're an in-between size I would probably lean towards the smaller end of the scale.
Overall, this is a good buy. I have two different jackets, and this is the only one I wear now. It looks great, fits great, and is both durable and waterproof.
