After reading many reviews for a lightweight warm jacket I went with the Xenon X hoodie. I just spent a week I the mountains with temps hovering around the mid to low 30 degrees and I am glad to report that with nothing more than a t-shirt and this jacket I was warm! This trip was a vacation and by no means humping gear in the wilderness but a sight seeing trip to the concrete jungle. I am happy with my decision to purchase this item...can't go wrong. For what it is why I am 5'-10" 180 lbs.
