The price on those is in line, or a bit less than the stuff I wear, and they look pretty good, but I’ve never heard of them.
I’d always be cautious about wearing a jacket “rated to -54” because conditions change so much in a day, or even a couple miles, that I’d want the ability to add or drop clothes throughout the day… as an example, I was working north of Denali Park last week. In town on the highway, it was +33 degrees (in which case I just wear my daily wear jeans and jacket). 3 miles north of town it was +5, and a few miles past that, it was -12.
Huge difference for spending a couple hours outside, and a completely different type of dress.
