1 Piece Suits

About

One piece suits are the benchmark for track and fast road riding, joining torso and legs into a single leather shell with no waist gap to creep open in a slide. This range spans Shark Leathers, Berik, Difi and Macna in race-cut leather built around a tucked, forward riding position. One piece leather is the strongest abrasion package you can wear on a motorcycle. Full-grain cowhide across race suits runs 1.2mm to 1.4mm thick, the depth that lets leather char and resist tearing through a long slide rather than splitting on first contact. Race-cut leather suits sit at the EN 17092 AAA tier, the highest abrasion class in the standard, above AA and A. Spec Track / race riding Fast road riding Construction 1 piece, zero waist gap 1 piece or zip-link 2 piece EN 17092 class AAA abrasion AAA or AA abrasion Leather thickness 1.3mm to 1.4mm cowhide 1.2mm to 1.3mm cowhide Armour standard CE Level 2 at 4 points CE Level 1 minimum at 4 points Stretch panels Accordion at lumbar and knees Accordion at lumbar Fit is the safety feature on a one piece suit. A race suit should feel tight standing up and correct in the tuck, because armour only protects when it sits over the joint. The 4 impact zones (shoulders, elbows, hips, knees) must hold CE armour, and CE Level 2 absorbs more impact energy than CE Level 1 at the same point. Look for accordion stretch across the lower back and behind the knees so the suit moves with a 30 to 45 degree forward lean without pulling tight across the shoulders. Sizing runs to the rider, not the wardrobe. Most race suits track chest measurement in 4cm steps, and a 2cm error at the chest moves armour off the joint. Perforated leather drops running temperature for summer track days while holding the same 1.3mm slide rating and EN 17092 AAA class. Pair a one piece with full gauntlet gloves and over-the-ankle boots so wrists and ankles are covered to the same standard.
