Alpinestars ACR Air-Flo Mesh Pants
Sizing Information:
Use the chart below to choose a waist size. If you plan to wear these over your street clothes, choose a size that offers a waist size about 2” larger than your actual measured waist size. We’ve listed a waist size range since the pants have a pretty effective waist size adjustment feature. The largest waist size listed for each pant size would be the waist size with the adjusters fully open. Just to give you an example, I wear a 36” jean so I’d choose an XL with a waist range of 34 to 38. So if I wore these pants over underwear, I’d adjust the waist down some, but if I wore them over jeans, the pants would be about right with the waist adjusters fully open at 38”.
| Pant Size | Waist (inches) | Inseam (inches) |
| Small | 27-32 | 32 |
| Medium | 30-33 | 33 |
| Large | 32-35 | 33.5 |
| XL | 34-38 | 33.5 |
| XXL | 35-40 | 34 |
| XXXL | 36-41 | 34 |
| XXXXL | 38-42 | 34.5 |
The main features this pant has over the Air-Flo is the attachment zipper for connection to Alpinestars jackets and the handy zippers near the waist to allow you to reach into your jeans from the outside without taking the pants off. Like the previous version, the leg zippers go all the way from the ankle to up above your knee and then cross over the pant face. This makes it VERY easy to slip the pants over street clothes—great for commuters. It really is as simple as putting on a pair of shorts, even with jeans or slacks on. The pants come with armor in the knees. Take the “View Larger Pictures” link above to see the pants up close.
