With well-over a year’s worth of testing across three separate sets, we’ve sure given Leatt’s GPX 5.5 IKS pants and Ultraweld jerseys the Enduro21 tested treatment. Here’s what we found…


Fast growing apparel manufacturer, Leatt has a reputation for strong design, function and above all safety in their riding gear. 

Building from a whole new outlook on rider safety with their innovative neck brace over a decade ago, the South African brand has since moved forward a long way to branch across a wide remit, taking in all aspects of off-road riding with a comprehensive range to match. 

One thing that marks Leatt out is their design – a bold and unique look to riding kit matches attention to detail and function.

Leatt’s GPX 5.5 offering is their top-of-the-range, high function kit. Stacked with features for comfort and body movement, we’re also taking a look here at the IKS pants – designed specifically for knee braces to fit underneath when riding.

They say:

The top-of-the-line factory racing GPX 5.5 pants are lightweight and flexible with more than 75% made from a durable Ripstop stretch material. Offering a tailored, pre-curved, stretch fit with 3D fully floating knee cap reinforcement, the GPX5.5 pants offer comfort as well as protection during riding. 

The Internal Knee Brace System (IKS) prevents knee brace wear and tear and is compatible with the Leatt knee brace, as well as all other leading knee braces. 

A durable seat area and four-layer inner leg is made of high-tech NanoGrip material known for its durability and superior wet/dry grip properties. The knee area also has four-point knee ventilation and all seams have multi-row safety stitching.

Other features are the adjustable front and side waist straps, 360 ̊ silicone waist grip and YKK highest quality zippers for a rock-solid fit that works with and without knee and hip protectors.

The super-light, ‘Ultraweld’ jersey is ventilated with air channels, laser-cut vents and stretch mesh to ensure a tight fit. This enables you to ride with or without body armour and the collar is designed to be compatible with or without a neck brace. 

The rear silicone grip keeps the jersey tucked into the pants during rides and the welded seams at the cuff and hem make it ultra-comfortable. 

Reinforced with Brush Guard over the elbows, an ultra-thin flex film that is feather-light, it greatly increases the scratch and abrasion resistance properties of the stretch material.

We say:

We’ve had GPX 5.5 kit on test for well over a year now and tested it in some tough events including the three-hour Weston Beach Race, October 2017. 

The short verdict is the kit has been good all the way. Quality and wear across three sets of riding pants and jerseys has been consistent and our oldest set has taken a beating over many hours of riding (including the sand race above). The jersey too stands up well to snagging from branches and thorns in the woods.

The look or design gets a big thumbs up from us – particularly this grey/teal colour, which is a hit with our guy Philippe in Portugal (he’s all about the style).

Distinct design

Across the different colours in the Leatt range the look is quite distinct from other riding kit on the market and it has a quality about it that you don’t always find. 

Both the pants and jersey have a tight fit, something both testers prefer rather than baggy gear. The jersey particularly is ultra-light to wear too with good ventilation in different riding temperatures.  

Another good feature on the jersey is the collar, which fits well with a neck brace, plus strategic silicone grip patches on the cuffs and rear bottom. Working with the additional silicone grip on the pants waist band it keeps things in place while riding.

Knee brace compatible

A strong positive for the pants is fitment with knee braces – part of the IKS model remit is to be compatible with braces. The proof is in the pudding and they do accommodate different types of knee braces well, fitting around them well when riding and allowing good movement without puling tight or hitching the pants down at you backside. It is an aspect that marks them out from some pants on the market that haven’t had knee brace wearing incorporated in the design.
