Outdoorsmen actually used to wear a scratchy wool baselayer intentionally, to stimulate circulation. We're not into that. Paradise is ultrasoft, highly breathable and moves with you just about as easily as another layer of skin. It lives up to its name - nothing's softer or performs better against your skin. It's also moisture - wicking, quick-drying and, for the sake of your tent mates, resistant to odors (no offense). Ultra-comfortable, clean-finished waist. Machine wash. Precision layering. "In the mountains, many times your baselayer is your outer layer. it should feel soft against your skin, perform in the outdoors and look good off the mountain." - Peter Whittaker
