In order to be a ninja, one must possess intelligence and physical acumen. Sheep have neither, but their fleece is known to cover ninjas the world over. We think. SmartWool made its Men's MerinoMax Full-Zip Sweater with merino wool. This body-hugging piece gives you an under-the-radar profile when being discrete is essential to your mission. Slipping around unseen is only part of the problem—you also don't want them to smell you coming. Merino maintains your body temperature by moving moisture vapor to the surface for rapid evaporation. Odor-causing bugs can't grow where there isn't perspiration, and you won't get sidetracked by sweat-started shivers. A zipper garage protects your chin against chafing and thumbholes keep your sleeves in place, even when you're practicing with your nunchucks. If covert ops aren't your thing, this soft jacket shines as a baselayer or stand-alone piece for more tame winter activities (like running and skiing, to name a few).
