It is characterized as polar, but what exactly does that mean?
Polar-type wool made of polyester 280g/m²
Today, when I wore it, I can confidently tell you not to expect a heater with sleeves; it is almost as warm as athletic hoodies from serious brands without the advantage of the hood.
I give it a 3 instead of a 4 because the description "polar" is misleading

This jacket is perfect! I first got the blue one and fell in love with it, then I got the black one, and then they only had red... so I got that one too. It fits perfectly and feels incredibly warm. It makes you want to put your hands in the pockets and snuggle. Good quality and stitching. I hope they continue to sell it and come out with more colors. There are sooo many colors out there... The red is super red, couldn't be any redder, and I don't wear it outside because it attracts all the attention, I have it for home. Also, the price is very good for the quality of the garment, well done to them!

The jacket is simply perfect! Very good quality construction and it has a perfect fit. I got the blue one first and I was thrilled with the comfort and warmth it provides. Then I got the other two colors as well. Unfortunately, the black one is a bit problematic because every speck of dust or lint that sticks to the fur is visible and also the red one is eye-catching like Little Red Riding Hood, it stands out... it's a shame it doesn't come in other colors. I would gladly get more because they are comfortable to wear both at work and outside all winter long!
