Warm and comfy
I've been a fan of Mountain Hardwear and Northface products, so I was hesitant to try a different brand. First off, REI products are equally as good as the above labels. But they are better because it is less expensive. I snagged this one on sale, which was a bonus. The product is warm, soft, and breathable for those who lead an active life. I just finished shoveling 8 inches of snow with this and my Mountain Hardwear windstopper. It kept me warm and dry. Loved it so much, I got two more before the sale ends.
