EvoShield's Chest & Back Guard features 1 custom molding chest Shield and 2 custom molding back Shields. The Shields slide into the compression shirt pockets and mold to the body for comfotable, custom fit protection. Custom-molding pads begin soft and flexible, transform to hard and protective in minutes. Impact is dispersed, not absorbed like in foams and hard plastics. Comfortable compression fit doesn’t interfere with mobility – move with freedom and confidence. Molds to the contours of your body. Fits like a second skin. Once formed, Shields provide season long protection. Sweat wicking performance fabric keeps you dry and comfortable. Tough flat-lock seams provide full season durability. Shirt is machine washable. Shields are removable and hand washable.
