Womens Sphere Short Sleeve Low Crewe Stripe XL - Tasman. The Women's Sphere Short Sleeve Low Crew Stripe shirt incorporates our Cool-Lite⢠fiber, a unique construction of wool and TENCELî, giving it outstanding comfort and breathability in summer, and also a different look. Just the wool is dyed, so the fabric has tiny stripes that give it a heathered-effect. Casual yet interesting, the slightly open neckline and outstanding breathability of the fabric make Sphere a perfect travel and adventure shirt.
