The Firstar Offside Womens Lace Up Longsleeve Top was designed using MST Technology, which dissipates most of the odor, heat and moisture that builds up during work-outs. Its loose-fit will keep you relaxed while the Bact-Out material helps to keep bacteria away from your body at all times.The style of the Lace Up Top stands out as much as the design. With a referee armband on the right bicep and actual hockey laces stitching up the left shoulder, the Offside Lace Up Top is a must for any female hockey enthusiast.
