The prAna New Moon Long-Sleeve Top blends hemp, recycled polyester, and TENCEL lyocell into a drapey, breathable fabric that holds up through an intense yoga session. A low-cut back and boat neck let a favorite layer underneath show through, while the loose long-sleeve silhouette keeps the fit relaxed rather than restrictive. The TENCEL content comes from a closed-loop process that uses less water and energy to produce.
