The pathfinder comes in a few different weights. Heavy, Extra Heavy, and Blanket weight. I've got one of each and can tell a difference. I wouldn't call the heavy a true heavy weight. I feel it's more mid weight. I think the majority of the patterns are Extra heavy, which is pretty heavy. Only a few patterns come in the blanket weight. I would call that a true extra heavy weight. I just got them for Christmas, so I haven't had a chance to test any of them, I'm just going by how they feel in my hands. I got the heavy weight first. I was a little disappointed at first. I think it will be fine for everyday wear, but I think it's a little light for something I would wear hunting. Maybe early season on a cool morning. The extra heavy is what I would want personally for a hunting garment.
Also, of the (3) different weights, the heavy is by far the "itchiest" of them all. It's not bad, but it's far from merino. I wouldn't wear it next to my skin. The two heavier weights are much softer.
I agree with your sizing comment. I read a lot of posts on another forum. They all said these were oversized, so I thought I needed a smaller size. I ended up exchanging it for the size I normally wear.
I really like these pieces. I'd recommend them to anyone who was looking for this style of clothing. When I wanted to exchange for a different size, I called and spoke with Mrs. Asbell and she was very nice. I'd buy another if I didn't already have 3.
