The materials and construction (double-sewn seams where needed/desired, front pockets are riveted) are okay.  Denim weight is somewhat lighter (and softer) than my Carhartt's and the polyester lining, though not as bulky as the Carhartt cotton flannel lining, does a decent job in terms of warmth and wind . Waist and inseam fit as described.  The chief difference here is the somewhat over-generous diameter of the legs.

On a more positive note, the legs do leave ample room if additional thermal protection (such as long johns) is necessary due to the wearing environment and also allows extra room if above-the-ankle footwear is worn.

As an Alaskan, I can see the possibility for the need of additional warmth, so the relative bagginess isn't a deal breaker for me.

Good value for the money.
