The Knox Shield Spectra jeans are the pinnacle of Knox's jeans collection with a high-performance Class AAA rating - normally reserved for one-piece suits. Made from Ultra-High-Molecular-Weight Polyethylene fibres (UHMWP) and Spectra fabric with added stretch for excellent freedom of movement and comfort in the riding position. Spectra is one of the world's strongest, yet lightest fabrics and is 40% stronger than Aramid. It also offers heat resistance tested to EN ISO 11612:2015 and passes the requirements for Radiant and Contact heat. The Shield Spectra jeans also feature CE Knox Micro-Lock knee and hip protectors. The Micro-Lock armour comes with a 5-year Knox guarantee when registered. The casual jean styling looks great on and off the bike with a tapered fit leg and the classic five-pocket zip fly design and leather branding at the waist. Premium YKK zips at the fly give a secure closure, and these are machine washable - just remove the armour and read the washing instructions. Knox branded rivets, key ring and waist button add to the look.
