📋 Technical Specifications

📏 Size Guide

Official Macna "Mens Jeans" size chart, fully reported and also converted to inches; sizes with ✔ are those we sell. ⚠️ Denim numbering (28, 30, 32…) does not correspond to body waist measurement: refer to the measurements in the table, not the number on the label. Waist is measured at navel height, hips at the widest point of the pelvis; if you fall between two sizes, choose the larger one. Macna publishes short inseams from size 34 upwards: for our "32 Short" the measurement is not declared.

🎯 Perfect for whom

These are the jeans for those who use their motorcycle every day in the city and don't want to change once they arrive. On hot days, a technical suit is too much: here, the stretchy denim allows movement, the aramid under the knees and on the hips works where needed, and CE protectors are already inside. Once off the bike, they remain a pair of jeans, and the Backonnect keeps them attached to the jacket when riding seriously.

❓ Frequently Asked Questions

What colour is this version of the Macna Stone?
This is the Black colour, code 165.4003.101: black denim, with slight fading on the thighs and knees. Each Macna Stone colour is a separate listing, with its own article code and barcode, so the size you choose always matches the colour you are looking at.

Are the protectors included in the price?
Knee protectors are included: they are CE level 1 certified and fit into dedicated internal pockets. Hip protectors are not included, but the jeans have pre-fitted pockets to accommodate them. The garment itself is CE approved according to EN 17092-4 Class A.

What is the Backonnect system?
Backonnect is the short zipper sewn on the back of the jeans' waist. It is used to attach the trousers to a jacket with the same pre-fitting: Macna presents it as a system to prevent the jacket from riding up during an accident, leaving the lower back exposed.

What size should I get and what does "Short" mean?
Sizes follow denim numbering (28, 30, 32…), which does not correspond to body waist measurement: measure yourself and compare with the table above, reported in centimeters and inches, and if you fall between two sizes, take the larger one. "Short" sizes have the same waist and hip measurements but a shortened inseam: Macna states 76 cm (29.9 in) instead of 81 cm (31.9 in).

What material are they made of?
The fabric is a stretch cotton denim composed of 90% cotton, 8% polyester, and 2% elastane. On the knees, hips, and seat, the denim is reinforced with aramid fiber, which resists abrasion much longer than cotton alone during slides.

Are these original Macna jeans?
Yes. Moon Bike S.r.l. is an authorized Macna dealer: these Stone items are original, new, and never worn, supplied with invoice and legal warranty. We ship from Cercola, in the province of Naples, with appropriate packaging for the garment.
