Best-selling and buttery-soft, the Baritone Collection is ultra comfortable when youre lounging, and beefed up with ActiveTemp when youre moving. Its soft, brushed interior makes it perfect for cold weather activities that demand warmth, stretch, movement, and moisture management. Each Melody piece uses ActiveTemp, the thermo-regulating technology that adjusts to your body temperature to keep you cool, dry, and comfortable during high-exertion activities.
