I have had it for just over 2 months and I have covered many kilometers with it.
Initially, it is indeed very warm and does not let rain through (at least not yet).
The ventilation, especially compared to the competition, is well below average as the pockets are very small and there is no ventilation zipper on the sleeves.
The overall construction quality is well below average with just 2 months of daily use, the strap of the thermal lining has torn.
The velcro on the main front pockets has completely lost its properties, resulting in the pockets opening while in motion!
I would recommend avoiding it, it does the basics decently but it will barely last a winter season of use...

Purchase for travel use! It passed the first test successfully with a 3-day trip on a mountainous route. I didn't feel the slightest sensation of cold at temperatures of 7-8 degrees and speeds of 100-120 km/h. I was wearing thermal clothing inside and a thin t-shirt. I didn't experience any rain, so I will come back with an update. Good fit, good buttons, and zippers.
