Garments made from a composite, protective fabric are disclosed. The composite fabric has textile layers placed in proximity to metallic mesh layers of woven stainless steel mesh. The metal mesh layers formed from any metal which forms suitable fibers. The textile layers are fabric formed with well-known fabric fibers selected from those including para-aramid fibers, meta-aramid fibers, ultra-high molecular weight polyethylene fibers, polyethylene terephthalate fibers, cellulose fibers, polyamide fibers, a mixture of para-aramid fibers and meta-aramid fibers, and a mixture of para-aramid fibers and carbon fibers. Forming the non-metal textile layers is by any suitable method for interlacing yarns including weaving, knitting, crocheting, knotting, or felting, or combinations thereof. The garments made using the fabric include gloves, bullet proof vests and chain-saw resistant trousers.

An article of weightlifting equipment includes a weightlifting jacket having a main vest-shaped body having a front covering the torso of a user, a back connected to the front, and one or more pads that provide a cushion to provide comfort and to protect the user from injury by reducing the force on the body caused by a barbell. The pads include a front pad that is positioned on the portion of the jacket front to cover the lower torso of a user wearing the weightlifting jacket. The jacket also includes one or more adjustable straps that allow the jacket to be fitted for users of different sizes. The equipment can have other forms, such as a belt instead of a jacket for positioning the torso pad.

A system, method, and blocking pad for receiving strikes from a special individual. The blocking pad includes a pad configured to receive the blows from the special individual. The blocking pad further includes a number of handles connected to a back of the pad. The number of handles include at least two handles in a middle portion of the back of the pad and at least a handle at ends of the pad.

An impact protection foam includes the reaction product of an isocyanate component and an isocyanate-reactive component. The isocyanate component includes at least one isocyanate. The isocyanate-reactive component includes from 20 wt % to 80 wt % of a hydrophobic polyol component and from 20 wt % to 80 wt % of a hydrophilic polyol component, based on the total weight of the isocyanate reactive component. The hydrophobic polyol component includes at least one natural oil hydrophobic polyol, and the hydrophilic polyol component includes at least a polyether polyol having a number average molecular weight from 3,000 g/mol to 10,000 g/mol and a primary hydroxyl content of at least 50 wt %. The isocyanate index is from 50-120. The foam article has a rate of energy dissipation less than 35 KN over the temperature range from 10 C to 40 C and a Shore A hardness of less than 55 at both 23° C. and −10° C.

A body armor system includes a pouch and an armor plate and hydration bladder disposed within the pouch. The shape of the hydration bladder corresponds to the shape of the armor plate and is dimensioned such that the hydration bladder is hidden behind the armor plate during use. The pouch includes a front pouch in which the armor plate is disposed and a rear pouch in which the hydration bladder is disposed. The hydration bladder can be filled with fluid, which is configured to absorb and disperse ballistic energy transferred from the armor plate when struck.

A self-modelling padding for garments or supports which has an elastomeric matrix having a cross-linked, three-dimensional open cell structure, and a self-modelling paste embedded in the elastomeric matrix is provided. The elastomeric matrix is configured to have a shape memory. The self-modelling paste has a plastic behavior.

A protective hood for a garment is provided. The hood can have a multi-layered sidewall that has an inner fabric layer and an outer fabric layer that cooperate to define a first pocket. A padding layer is positioned within the pocket.
