Synthetic garments are always compared to wool because, quite frankly, nothing is better for keeping you warm. That's why sheep wear it. The only problem is its inherent itchiness and need for dry cleaning. Ibex, a new line of clothing featuring natural fabrics, solves those problems with the Zepher T-Neck. Made of superfine merino wool, this nicely constructed shirt is velvety soft and can be tossed in the washing machine. It's the perfect layering shirt for cold-weather hunting, and because wool is naturally antimicrobial, it doesn't acquire that lovely synthetic funk after a few days' wear.
