Abstract: A headwear insert, system, and methods to define and control the shape of an article of headwear are provided which may be used to change the shape of an already manufactured cap to the shape of the insert, completely changing the shape and style, and the headwear insert may include an elongated body having a first end, a second end, an elongated upper surface, an elongated lower surface, an elongated first side surface, an elongated second side surface, and a curved body section. The elongated upper surface, the elongated lower surface, the elongated first side surface, and the elongated second side surface may each extend between the first end and the second end, and the curved body section may be formed by a first portion of the elongated upper surface having a convex curve shape and by a first portion of the elongated lower surface having a concave curve shape.

Abstract: An artificial turf infill comprising an organic material including ground walnut shells having each organic particle completely coated with an anti-microbial agent. Water-retaining particles are added to the infill ranging between 0 and 60% of total weight of the mixture. Synthetic, ecologically-safe resilient granules preferably between approximately 20% and 25% by weight may be added to the infill to improve shock attenuation (lower G-max) properties of the infill mixture. The water-retaining particles and synthetic resilient granules within the infill are completely coated with the anti-microbial agent.
