Speedo LZR Racer X Technology Guide

Speedo LZR Racer X Technology


The new Fastskin LZR Racer X design combines four crucial performance components: compression, construction, sensitivity, and support, which together create the psychologically important feeling of being fast, which can lead to an actual improvement in performance. This suit is a hybrid of increased core support and compression, which together gives athletes a better feel for the water. In both male and female suits, the Fastskin LZR Racer X is constructed using two fabrics: LZR Racer CompreX and LZR Racer PulseLite. Unique to Speedo, LZR Racer CompreX uses smart-stretch technology to provide compression one-way (horizontally) and stretch the other way (vertically) in the same fabric. It is Speedo's highest compression fabric and targeted where it's most needed, i.e. around big muscle groups such as the hips, glutes and quads, whilst also facilitating freedom of movement.
Reducing drag but increasing muscle efficiency. LZR Racer CompreX uses one-way stretch technology, where it stretches vertically, allowing swimmers freedom of movement during their stroke but is resistant to horizontal stretching. This provides high compression and reduces drag while increasing muscle efficiency.
Improving the linkage of the muscular kinetic chain. The support seams enhance the link between muscles of the upper and lower body. They connect major muscles of the thigh, back, and shoulders.

The support seam intersects at the hip bone, allowing rotation, then runs across the lower back with an identifiable 'X' shape. The construction of the seams provides feedback to the swimmer, maintaining a better position in the water and a high-leg kick.

Hi, I am a distance swimmer that also does a little bit of everything. I have raced in the LZR X before but I am trying to decide if this is the best suit for me or if I should go with an Arena. I am 5 2 and have bigger thighs and hips. What suit would you recommend?

Hello Emma,
Arena has a lot of great tech suits as well as Speedo. The LZR X has the most compression out of the Speedo line. If you like the compression but want to try something different, the Arena Carbon Flex would be a great option. If you want to try something with less compression, the Arena Carbon Air or the Speedo LZR Racer Elite 2 would both be great options. All of these suits will work for all swim style/distances however, most distance swimmers like less compression in their tech suits. This really comes down to personal preference though. We hope this helps!

Hi!
Any of the Speedo suits would be fine for sprinting.. Speedo Fastskin LZR Racer Elite 2 Recordbreaker Kneeskin Tech Suit is one of the more popular options.

Which is the best suit for a highly competitive breaststroker. She has worn the closed back Speedo in the past. The Laser X is too hard to get on over her hips. Tiny waist compared to hips. I read there are better suits for better strokes.

Hello!
If you feel like the LZR X is too hard to get into, the Arena Carbon Flex is a great option for breaststroke.

Hello Hoyoung!
The Arena carbon flex is a great suit with the flexibility that he would need when doing the breaststroke.

Please, what is the expected durability of a LZR for men?

Hi Alexandre, The expected durability of an LZR ranges depending on how it's taken care of. If you are following Speedo's care instructions (rinsing the suit in cold water immediately after each use, not washing suit with any detergent, and always hang-drying in a well-ventilated space) then generally they can last UP TO 8 swim meets. Tech suits are delicate, so we suggest being careful when putting them on to avoid any tearing of the material with sharp nails. I hope this is helpful!

My daughter swims fly and backstroke. I was wondering if there is a difference between swimming on an open back compared to a closed back. Which is best for those strokes? Do the open back give you more freedom for arm movement? Thanks!

Hi Rosa,
The advantage of the closed back is it will provide a tiny bit more compression with the back material, whereas the open back does not have this extra material. Aside from that difference, the open and closed back depend on personal preference and both will provide the same amount of range of motion. If you have any questions, feel free to reach us anytime!

I just wondering about how to look after the LZR Racer X for men ...?
Swimoutlet.com

Hi Randy,
After every swim session, wash your swimsuit by hand with a mild soap and water. We would recommend turning your swimsuit inside out when you wash it to avoid damaging the delicate outer layer. Allow your suit to dry naturally when drying outside, do not hang in direct sunlight. Try to make sure that your swimsuit is laid out flat to dry to avoid folds and wrinkles. Let us know if you have any questions. Have a great day!
