Mother Nature knows what she’s doing, and wool is a great example—the original insulator is still the best. The Sierra Hood from IceBreaker kept me warm all hunting season: as an outer layer for cool mornings and evenings in early fall, and as a mid-layer when daily temps plummeted in November and December. Sleek and form-fitting, with a dark-brown Mossy Oak Breakup camo pattern, this hoodie became my go-to garment for chasing big game and upland birds alike. The best part? None of those girly thumb-holes to catch on zippers or other protruding objects. $220; icebreaker.com.
