DescriptionThe whole story▼

Acid Yellow is the brightest version of the 2027 Leatt Moto 5.5 UltraWeld Jersey. Its pale neon-yellow base with light blue watercolour clouds makes the rider easy to spot, while the jersey underneath is Leatt's ultra-light race construction: 180 g in size L, 360° stretch and 238 laser-cut vents.

It is meant for motocross and supercross at full race pace.

Key Features

  • Ultra-light race jersey, 180 g in size L according to Leatt
  • Virtually seamless build with taped seams
  • Abrasion-resistant zones where the jersey takes wear
  • Fabric with a cooling function treatment
  • Improved durability in the washing machine
  • OEKO-TEX, REACH tested and PFAS(PFC)-free

Ventilation

Count them and you get 238: that is the number of laser-cut perforations Leatt places in the Moto 5.5 UltraWeld. Mesh sections add more air exchange, and a treatment on the fabric supports cooling. It is a ventilation setup for riders who are working at their limit.

Materials & Care

At 180 g in size L, according to the manufacturer, this jersey is built to weigh as little as possible, and Leatt quotes a saving of roughly 10% over the previous generation. Despite the low weight, washing-machine durability has been improved. Material credentials include bluesign® APPROVED, OEKO-TEX, REACH tested and PFAS(PFC)-free.

Three-Panel Build

Fewer seams mean less to rub. Instead of a patchwork of panels, this race jersey is shaped from three pieces of bluesign® APPROVED fabric, cut to the anatomy of a rider on the bike. Taped seams lie flat against the skin. The fabric itself combines compression, anti-snag and abrasion-resistant properties with high breathability.

Fit & Sizing

Expect a close fit. The 360° stretch lets the jersey move naturally with your body, while the semi-compression shoulders and sleeves stay put at speed. Because there is little excess fabric, the UltraWeld feels more like a second skin than a shirt. Available sizes: S to XXL.

Collar and Hem

As a neck brace manufacturer, Leatt has designed the neckline of the UltraWeld to work with its braces: a minimalist collarless cut that is comfortable with or without one. Further down, silicone at the hem grips the pants and keeps the jersey from creeping out during aggressive movement.

What you should know

A close race fit is not for everyone. Riders who prefer a relaxed jersey may find the UltraWeld snug, especially over protection. It offers no padding and no certification class, and with 238 perforations it is designed to let air in, not to keep rain out. Leatt sells it as a single jersey, without matching pants.

Colour

The jersey is a soft neon yellow overlaid with cloudy patches of light blue and mint, as if the colours had been painted wet on wet. A black Leatt logo panel sits on the chest and on the sleeve. The bright tone gives good visibility on track and on the trail. Light colours show mud and roost marks sooner, so expect to wash this one more often.
