Our Tri Sigma Aqua Rain Jacket by Charles River is made from 100% polyester polyurethane with heat-sealed seams for superior weather protection. Both wind & waterproof, this rain jacket also features underarm vents for air-flow circulation, a 2-way zipper and full-length wind-flap, and 3M™ Reflective trim on the front and back to provide high visibility in low light. Sigma Sigma Sigma's Greek letters are shown in white on the left chest for a classic look. Keep dry this season while still showing your Tri Sigma pride around campus!
