How Should Motorcycle Leathers Actually Fit?
Most riders find out their gear doesn't fit properly the hard way. In a slide, when the elbow armour has migrated halfway up the forearm, or the back protector has ridden up past their shoulder blades. Fit isn't just about comfort here. It's the difference between armour doing its job and armour being in the wrong place when it matters.
The armour has to sit on the joint, not near it
CE Level 2 armour only performs the way it's rated for if it's actually over the part of the body it's protecting. A jacket that's a size too big lets the shoulder and elbow pads shift in a fall, and once they've shifted, the impact lands somewhere the padding isn't. This is the biggest thing a standard size chart gets wrong. It assumes your proportions match an average build, and most riders' don't quite match it.
Snug, not tight
A well-fitted jacket or suit sits close to the body with your arms down, but still lets you lean into a riding position without pulling across the shoulders or riding up at the back. If you can't comfortably fake your riding stance while trying something on, it's not the right fit, whatever the label says.
New leather is firmer than it'll end up being. A jacket or suit that feels a touch snug in the first few weeks is normal. It softens and moves with you as it's worn in. That's a different thing entirely from a jacket that's simply too small, which stays restrictive no matter how long you wear it, and never lets the armour sit where it should.
Pants and the knee slider problem
Leather pants and race suit legs need the knee armour centred on the kneecap while you're actually seated in riding position, not standing straight at the counter. A lot of off-the-rack pants get sized standing up, which means the knee protection and the external sliders on a race suit end up too high once you're on the bike.
Why made-to-measure actually solves this
The only reliable way to get armour placement right for your own proportions is to build the suit around your measurements instead of squeezing your body into a stock size. That's the whole idea behind Motorce custom race suits and custom leather jackets: every piece is cut from your own measurements, taken either at a fitting or through our guided measurement form.
If you're not sure your current gear fits properly, there's a quick way to check. Get into your normal riding position and see whether the armour has moved. If it has, it's not doing its job.
