Men’s Shield Spectra® Denim Jeans – Black – Short


Size Guide

The pinnacle of the Knox jean collection due to their amazing strength and high-performance Class AAA rating, a class normally reserved for leather suits.

The Shield Jeans are a true single layer jean with no extra mesh lining like most single layer jeans and are made with a newly developed Spectra® denim. They look exactly like regular jeans but with incredible strength and durability.

Spectra ® is 40% stronger than aramid and fifteen times stronger than steel and is one of the world’s strongest and lightest fibres. Knox, being a Spectra partner have the privilege of being the first company to work with this new denim. The weave of the denim is patent pending and is entirely unique and delivers unparalleled strength in like for like weights.

This spectra denim not only has supreme strength, it also incorporates stretch for all day comfort. Additionally, Spectra repels moisture, so you stay dry. By pulling away heat from the body, Spectra fibre helps you to stay cool. Also, because Spectra fibre is stronger, it lasts longer. Non irritating and hypo allergenic.

There are invisible armour pockets with external access for easy removal of low-profile Knox CE Microlock protectors in the hip and knee that are fitted as standard.



The Shield Spectra Single Layer Jeans are the epitome of the Knox jean collection, offering unbeatable strength and performance with a Class AAA rating that meets EN17092-2:2020 standards.  Made from Ultra-High Molecular Weight Polyethylene fibres, these jeans are known for their high strength and durability, yet still provide added stretch for all-day comfort on a motorcycle.

Spectra® fabric, which is 40% stronger than aramid and fifteen times stronger than steel, offers not only exceptional strength but also repels moisture, keeping the rider dry and pulls heat from the body to keep them cool.  With regular wear and tear being less of a concern, these hypoallergenic jeans won’t cause irritation.

The jeans feature four invisible knee and hip armour pockets with easy external access for removal of low-profile Knox CE Micro-Lock protectors in knees.  These protectors come with a five-year guarantee when registered and are part of the Knox Seasonless Collection. Simply wear a waterproof overtrouser or base layer for added comfort.

With a carefully tailored and tapered fit, the Shield jeans are designed to look perfect both on and off the bike, with leather branding on the waist, Knox branded rivets, key ring, waist button, and YKK zips all adding to their high-quality finish. With four deep pockets and machine washability, these jeans are both stylish and practical.

The Shield Spectra Single Layer Jeans come in black or blue and are available in either a short 30” leg or a regular 33” leg.  Men’s sizes range from S to 3XL.

Waist: To work out your size, measure your waist in the position your trousers usually sit. As a guide, this is roughly 2 inches (approx 5-6cm) below your belly button. Once you have this measure, minus 2 inches (approx 5-6cm) from it to get your trouser size.

Inside Leg: Measure from the top of your inside leg down to your ankle. You should do this whilst standing to get a more accurate measure.

Please note: The measurements given are body measures and we recommend you do not measure over the clothing. Also please hold the tape measure firmly and not loosely as the measurement needs to be fitted.
