Was wondering if anyone had any opinions on the benefits of one type of fabric over the next. Specifically I'm planning on building a sleep system and clothing layers for next winter slowly as things go on the end-of-season sale racks. At Goodwill today I saw throw sized fleece blankets for $2 in various colors which I would stitch together for an anorak and sleeping bag liner. I'm trying to decide if I'd be better off going with the wool blankets for 20+ dollars each or the cheaper and more readily available fleece clothing. If you can speak from experience about this issue I'd sure like to hear what you have to say. I'm really concerned with warmth comparisons as well as sweat wicking properties, which is better when it gets wet, breathability, etc.
