This men's favorite is far more than a basic, it's a necessity. Crafted of a baby alpaca/silk blend, it's incredibly soft to the touch. It fares well over a t shirt just as well as a button-down, or under your favorite sportcoat. Unique channel stitch accents are found on the collar, shoulder, and elbow. Alcantara, an unrivaled vegan suede from Italy, offers durability and strength and is 100% carbon neutral. Double zip enclosure, side pockets, zip accents on cuff. Dual interior pockets, dual outer accent pockets.
