Product Details
The Helstons Trust men's motorcycle jacket in Dirty Brown combines substantial full-grain cowhide with strategically positioned stretch leather for easier movement on the bike. Its fitted cut, removable body-and-sleeve Thermo-Alu liner, rain-protection membrane and supplied removable protectors make it a practical road jacket with distinctive heritage character.

Protection and conformity
Removable protectors are supplied at the shoulders, elbows and back. Helstons describes the Trust as tested and compliant with CE requirements and indexes a separate Trust Dirty conformity document. A current standard, class and certificate validity could not be confirmed from the accessible official document, so this listing does not assign an EN 17092 class or protector level.

Product questions
Does the Trust Dirty include a back protector?
Yes. Removable protectors for the shoulders, elbows and back are supplied with the jacket.
Does its thermal liner include sleeves?
Yes. Helstons specifies a removable Thermo-Alu liner covering the body and sleeves, with dedicated wallet and phone pockets.
Is the jacket waterproof?
Helstons specifies a membrane for protection against rain, but no waterproof rating is published. Treat it as weather resistant rather than guaranteed waterproof in prolonged heavy rain.
How does the Trust fit?
Helstons describes it as a fitted men's jacket. Use the chest and waist measurements rather than choosing only by your usual casual-jacket size.
Leather care
Clean gently with Marseille-type soap and a clean, damp, non-abrasive cloth, rinse away soap residue and allow the leather to air dry. Feed it regularly with a suitable neutral leather cream or natural-wax product. Avoid machine washing, tumble drying, ironing, alcohol-based products, oils, abrasive contact, prolonged soaking and extended direct sunlight.
Moto Central fitting guidance
The jacket should allow comfortable arm movement while keeping each protector securely positioned. Moto Central can help assess the fitted cut with your usual riding layers and gloves in our showroom.
