Designed for active support, the soft and breathable Merino Blend 125 Cool-Lite™ Sprite Racerback Bra features an open back design that improves freedom of movement as well as icebreaker's jersey Cool-Lite™ fabric, which blends TENCEL™ Lyocell and merino wool to naturally keep you cool and odour-free when you're on the move. Flatlock stitching and a no-side-seam design prevents underarm chafing when you're on the move. Soft merino wool and TENCEL™ Lyocell, a sustainable plastic-free lyocell, combine to create icebreaker Cool-Lite™, a lightweight, breathable and quick drying fabric. Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics.
