The pants are sold in ordinary US Alpha sizes. To help you get the right size, we’ve developed a chart that shows Alpinestars “official” estimate of size along side our own size estimates based on measurements of the actual products. Alpinestars size chart information was pulled from their own website and from sales literature supplied to their dealers (sizing info is new for 2021 season and will differ from older size charts on our site). Generally speaking, we find the pants to run close to their size estimates in smaller sizes, but in the larger size ranges, the pants run increasingly smaller than what Alpinestar’s information indicates.
To find a fit, we advise you to use a tape to measure your waist and choose a size from the chart using our recommendations. You’ll want to measure yourself up a bit higher on your waist than ordinary jeans because protective pants like this are a little higher waisted. Take the link below if you need advice on how to measure. Please note that we are listing a waist size range for each pant because the pants have adjustment tabs on the waist that allow you to snug them down if needed (but they do not get bigger).
With this particular pant, if you find yourself between sizes in the chart, I’d advise you to choose the larger. These pants have a generous thermal liner which makes them run a bit more snugly through the legs, and also they are equipped with suspenders to help hold them up, so if you get a waist that is slightly bigger than ideal, the suspenders will help you out.
