I bought a wool sweater. I went internet shopping and thought I had decided on a Fjallraven, but the store that sold them could not answer my question, so I emailed Fjallraven USA and they never got back to me. Oh well. I ended up with an LL Bean at half the cost. My deciding factor was the sweater I thought I wanted was listed at 15oz and the LLB sweater I ended up getting was 21oz. That's all I had wanted to ask Fjallraven, I wanted a thick sweater and how did the one I thought I wanted compare to their others. Maybe they had what I wanted, but we'll never know. And just to say, I did not want to jump into the $3-400 range. So my LLB sweater arrived yesterday. Perfect fit! Really nice looking sweater and 100% Merino wool with cotton wear patches on the arms and shoulders. But it sure does feel thin. It's not as thick as an older wool sweater I had years ago. Maybe that doesn't matter? I don't want to wear a lot of layers when I go out. I want to wear a T, a sweater and my coat as an outer garment. I will be testing out the sweater today. I am hoping that being wool it will be warmer than a sweatshirt, which was warm enough a few days ago, but truth be told my sweatshirts are thicker than this sweater. Maybe it's a psychological thing. Maybe I'm thinking I need a thick under layer, when with today's weaves maybe I don't. But the way your mind works can affect how cold you feel, IMO. I could not imagine taking my coat off with this sweater in winter weather the way I used to years ago with my other sweater. For instance, to dress a deer or when I am exerting myself. Are thick wool sweaters a thing of the past? Or is that when you make the jump into the higher priced range? Not every maker lists a fabric weight, nor gets back to your emails and phone calls, so it's hard to compare equally. What say you wool wearers?
