Whether you're hitting the track, commuting, or preparing for an epic adventure tour, having the right jacket fit is crucial for both safety and comfort.
For example, getting your RST jacket size correct means you'll enjoy every ride to the fullest, knowing your armour is sitting exactly where it needs to be. To help you find the perfect fit, we've put together this comprehensive RST motorcycle jacket size guide so you can shop with absolute confidence.
How to measure for RST jacket sizing

Before diving into the RST jacket size chart, you need to know your physical measurements. Grab a fabric tape measure and, for men, measure around the fullest part of your chest, keeping the tape flat against your body. For women's sizes, measure around the fullest part of your bust, the narrowest part of your waist, and the fullest part of your hips.
RST Leather Jacket Sizing

If you're looking for that second-skin feel for track days or spirited road riding, getting your RST leather jacket sizing right is essential. Leather will naturally stretch and mould to your unique body shape over time, so you want a snug fit straight out of the box.
Our RST leather jacket size guide below will help you find the perfect size before you buy. Typically, your UK chest measurement in inches corresponds directly to your UK jacket size. For example, if you measure a 42-inch chest, look for a UK size 42 (M). Be sure to match the sizes on our product pages to the RST leather jacket size chart below to find the perfect fit for the specific model you're eyeing.
RST Textile Jacket Sizing

For touring, commuting, and all-weather riding, textiles are the go-to. RST textile jacket sizing tends to be slightly more forgiving than race leather, accommodating removable waterproof and base layers. However, the fundamental RST motorbike jacket sizes remain the same.
When looking at an RST textile jacket size chart, keep in mind what you plan to wear underneath. If you commute in thick winter layers or office wear, consider how that affects your overall fit. Always double-check our RST motorbike jacket size guide below before adding your new gear to your basket!

RST ladies' jacket sizing
For female riders, RST jackets offer a fantastic, ergonomically tailored fit. RST ladies' jacket sizing follows standard UK high-street dress sizes (e.g., 8, 10, 12, 14, etc.), making it much easier to select the right gear without fuss. Whether you are after sport leather or waterproof textile, checking the RST ladies' motorcycle jacket size chart below will ensure your jacket flatters your shape while keeping the impact armour perfectly aligned on your shoulders and elbows.

RST Motorbike Jacket Sizing Frequently Asked Questions
Are RST jackets true to size?
Generally, yes! RST is a British brand that follows standard UK sizing, making their sizes very accurate for most riders. For example, if you measure a 44-inch chest, a size 44 UK (L) will usually fit.
However, a pro tip from our riding experts at Bikers World: if you are buying a heavily armoured adventure textile jacket with thick thermal liners, some riders prefer to go up one size to ensure full freedom of movement.
Similarly, their aggressive track-cut leathers are designed to be quite tight. Always review the specific RST jacket sizes for the style of jacket you're purchasing, and factor in how you prefer your gear to feel.
RST jackets: What size is medium?
When looking at a general men's size Medium (M) RST jacket, it typically corresponds to a UK size 42 (or Euro size 52), which fits a chest size of approximately 40 to 42 inches (102-107cm).
A woman's Medium (M) would generally fit a UK size 12 or an EU size 40. If your measurements roughly fit between 97-101cm bust, 80-84cm waist and 105-109cm hips, this is the size for you!
If your chest measures right on the border, consider how you want it to fit for your riding discipline: a snug, aerodynamic race fit or a slightly looser touring fit?
Can I return my RST jacket if I've bought the wrong size?
Absolutely! We understand that sometimes a jacket just doesn't fit exactly as you hoped, even when you've carefully followed the RST jacket sizes. At Bikers World, we are more than happy to accept returns within 30 days of purchase if the size isn't right for you.
To ensure a smooth refund process, please make sure your RST jacket meets these simple conditions:
-
It must be completely unused and unworn (trying it on for size in your living room is fine!).
-
It must be returned in its original packaging with all tags still attached.
How to return your RST jacket:
-
By Post: You can mail the jacket back to us. Please be aware that return shipping costs are your responsibility. We highly advise using a tracked and insured delivery service, as we cannot refund items that do not arrive back to us safely.
