The idea of wearing jeans in water dates from their very beginning and continues today. Jeans were originally shaped in only three sizes, and the user would jump into a body of water – either a stream, a pond, or a horse trench, to shrink them to fit. Today, Jeans are available in a variety of styles, from tight to loose fit, and are sold either pre-washed or shrink-to-fit. And may never even be worn in water, if the user chooses not to. However, the best method of ‘breaking-in’ Jeans ruins the same .buy them with a snug fit, wear them fresh, jump into a warm tub or spa — then swim, and allow them to dry-on, for a delicate fit.
Jeans are handy for outdoor activities, most athletics, and aquatics. The famous ‘top and Jeans’ — a neoprene jacket and shrink-to-fit Jeans ruins one of the best skin-diving and scuba suits or dive skins, offering protection from overexposure to the sun, stings, and scuff. This is especially important in open water and in the ocean – where salt water makes the diver more floating than in fresh water. The very same jeans that might feel ‘heavy’ to a novice swimmer when they go into a pool are a second skin to the experienced intrepid swimmer/diver in open water. Some swimmers and divers preserve specific pairs of jeans and dive skin jeans for the water, just as they do with their neoprene wetsuits and Lycra skins. The ideal approach is to be able to go from dry land to water and back to dry land wearing the same jeans or skins always when on, in, or underwater.
Jeans ‘skins’ provide swimmers and divers with additional expediency because in warm weather and climates where a complete dive skin is needed underwater, but not at the warmer plane (which might cause over-heating), the neoprene jacket can be removed and you can swim with just your jeans or with a lycra top. Most swimmers and diver merge their ‘skins’ with dive fins and a mask/snorkel for a very realistic and functional set of swim/dive gear. The surge in the denim fabric acts as shark tendrils in that it funnels the water over the swimmer/diver’s body letting them to become hydrodynamic and swim quicker underwater
Rescue Divers, marine First Responders, and Rescue Swimmers find jeans useful and a life-saving measure because of their versatility and because they guard the rescuer from sharp metal and fiberglass when doing saves follow-on from boat accidents and submerged vehicles. Jeans or skins enable the rescuer to be primed to swim and dive to respond to an in-water crisis without the added problem and waste of precious time required to ‘suit-up’. It must be remembered that if the rescuer is put at danger or injured while responding to a water emergency, then the victim might encounter more severe injury or even face death. In addition, the increased protection that Jeans and Skins provide in water allow the rescuer to look risks more boldly during storms and place themselves between the injured party and hazards in the water such as a rocky shoreline, piers and jettiesâ€™, to prevent the victim from the bottom of more injury during egress from the water. During World War II, relatives in the U.S. would send Jeans to their sons in the U.S. Navy and U.S. Marines stationed in the Pacific — because their fit was improved for swimming than the baggy dungarees issued by the military. In the U.S., Jeans first became widely accepted for swimming in the 1960’s with the introduction of “White Jeans” for surfers on the West Coast. White Jeans fit lean and tapered, and made of unbleached, un-shrunk denim, which shrank and bleached-out to an ideal white in chlorinated pools and in the ocean.
