First off, I am Attaquer loyal with cycling apparel. I love their gear, basically live in it haha!
That said, I am yet to understand this product and how to feel comfortable in it during a Victoria winter. We've had pretty artic feeling winds, cold rain, feels like temps well near or below zero and I've had to keep this item at home lacking confidence in its ability.
For the times I have worn it, layered the undergarments, I find myself way colder than necessary. Taking a second jacket (windproof) shouldn't be necessary, but I'd not go without now.
I love the design, I love the feel of it, but for myself, I can't get warm in it unless climbing.
I wouldn't suggest not buying this jacket, but it isn't for me.
Sorry Attaquer, I love you guys and my wardrobe of gear, I just fall short of liking this one.
