Abstract: A zipperless wetsuit constructed of a plurality of panels of material, some of which are stretchier than others. A majority of an upper body region of the wetsuit is constructed of panels of highly stretchable wetsuit material which utilizes a central layer of foam rubber and one or two surrounding laminates of nylon having a higher denier value than previous wetsuits. Strategic panels of the wetsuit are constructed of single nylon laminate foam rubber material which has maximum pliability and stretchability. A double-collar upper entryway allows a wearer to enter the suit without the use of a zipper. An inner collar includes an aperture which may be stretched apart to allow entry of the wearer. An outer collar extends over the head of the wearer in a continuous circle to seal the inner collar against the wearer's neck.

Abstract: An aquatic garment, such as a wet suit or dry suit formed of a water-impervious material having a thickness dimension sufficient to provide thermal insulation for a user during aquatic activities. The garment includes stretch areas having an array of grooves with a depth dimension sufficient to significantly increase the elasticity of the garment transverse to the grooves while maintaining the mechanical integrity and thermal insulation in the stretch area. Variation in the elasticity and in the direction or orientation of enhanced elasticity can be achieved by varying the spacing and direction along which the grooves extend. A method for formation of grooved aquatic garments to enhance their stretchability also is disclosed.
