Description

Speedo’s LZR Racer X Jammer is their latest top-of-the line swim jammer. They claim that it’s the “most advanced racing system yet.” We expect to see Ryan Lochte and other Speedo-sponsored swimmers competing in these jammers at the 2016 Olympic Games.

Speedo has a reputation for pushing the boundaries of swimsuit technology. Their Aqualab research facility in the UK explores new fabrics and manufacturing techniques to help swimmers shave time off their swims. They claim that the LZR Racer X’s “development has been made possible through analyses of the physical and psychological aspects of competitive swimming with over 330 elite swimmers, including multiple world-record holder Ryan Lochte, and 20 swimming experts from 26 countries.”

The suit is made from two fabrics — LZR Racer CompreX and LZR Racer PulseLite. The Pulselite is a lightweight fabrics with good endurance. The LZR Racer Comprex is engineered to provide one-way compression. The fabric compresses the muscles horizontally but stretches vertically, to allow the swimmer freedom-of-motion. The horizontal compression helps reduce the swimmer’s drag while increasing muscle efficiency.

The suit is composed of 65% Nylon and 35% LYCRA Spandex. Spandex is a popular fabric for use in jammers because it expands to form a tight fit. However, Spandex is not chlorine-resistance and, therefore, breaks down over time. Most jammers use a blend of fabrics, including Spandex or a similar material to give the suit a tight fit. In addition to a material that stretches, a jammer normally includes polyester or nylon. Speedo has chosen to use nylon over polyester in their LZR Racer X jammer. Nylon is more comfortable than Polyester, plus it absorbs less water. However, nylon tends to lose its color and shape faster than polyester suits. This jammer, like all technical suits, is made to be used for a swimmer’s most important races. It will become less effective with each use, although proper care and maintenance can extend the suit’s life.

The Speedo LZR Racer X Jammer is constructed using ultrasonically welded seams. This creates a very strong low-profile seam, which helps to cut down on the swimmer’s friction. The seams are designed in an “X” shape, thus giving the suit its name. According to Speedo, this x-shape helps connect the “muscular kinetic chain.”

The suit has been approved by FINA and is available in Bright Purple, Coral, Bright Green, Black. Speedo also offers a high waist version of this suit.

The Speedo LZR Racer X Jammer has received rave reviews, with many swimmers claiming this to be the best technical suit they have owned. Several swimmers, however, have expressed concerns with the fabric “rippling” around the seams. If you are looking for a high-end technical suit, the LZR Race X should be on your consideration list.
