At Prois, performance fabric choices are EVERYTHING. We believe the cornerstone to the best outdoor gear lies in its fabrics. Merino wool is far superior to the synthetic fabrics available on the market and we have sourced the highest quality merino available. Merino wool is naturally anti-microbial, odor-resistant, moisture-wicking, offers UV protection, static resistance, and the fibers are much finer than traditional wool. Because of this merino wool is not itchy like the wool produced by other breeds of sheep. This gives our Olann line an ultra-soft touch with none of the itchy feel of regular wool. Our Olann line is constructed of 96% Merino Wool and 4% Lycra. This racerback bra features athletic styling, and a wide elastic band for optimal support and comfort. This merino sports bra offers superior moisture and odor control, excellent support, and all day comfort.
