We measured a sampling of these jeans of different waist sizes and lengths and find they are much like other jeans you’d buy these days. They are just a bit “vanity” sized in the waist and pretty true in the length. Across the size run, the actual measured waist was about 2” larger than the stated waist size (typical vanity sizing). So my primary advice would be to buy the waist size you normally wear in jeans; you’ll likely find a fit.
If you aren’t sure whether your jeans are vanity sized like I’m describing, then either measure your waist where your normal jeans ride or measure your favorite pair of jeans to verify. You’ll probably find that you measure out a bit bigger than your normal jeans size and also the waist of your favorite jeans measures out an inch or two bigger than their stated size. If so, you will be on track following my advice. The denim used in these pants has a good deal of stretch to them, so if you are sometimes between sizes, I’d advise you to buy the smaller.
The inseam length is right about 33” inseam in the mid-size ranges. The smaller jeans measure just a touch shorter at around 32” and the biggest waist sizes are about 34”. These are slim fit jeans with a relatively low waist. The legs are slim enough to hold the armor in place well without being very snug. The ends of the jeans are tapered. If you are concerned about how big the leg end opening is, you can measure jeans you have and compare. These jeans measure about 6 1/2” across when laid flat in the smaller size ranges and about 7” across in the larger size jeans.
Note: We’ve notice just this season (2019), Alpinestars jeans run more “normal” than in past years (good news!). Previously, we found almost all Alpinestars jeans ran small, but these jeans run comparably with other riding jeans and normal jeans. So if own Alpinestars jeans from past years, you may find these jeans to fit larger, size for size.
Our Two Cents
Alpinestars has a new line of denim riding jeans for 2019. This Merc Denim pant is a “pre-washed” version of their two “standard” designs… this Merc and the Copper 2.
I mention both the Copper 2 and Merc Denim pants in the opening line because they are SO SIMILAR, I really can’t see a difference other than the color wash. The Cooper 2 color choices are dyed darkly where the Merc colors look more “pre-washed”.
Both these styles are made of a very nice 4 way stretch denim with separate Kevlar panels fitted in behind the denim shell in the impact prone areas… the seat and knees. Both are fitted with removable BioFlex armor in the knees. Hip armor is not included for the hips, but pockets are built into the pants if you want to add the hip armor. Bio-Flex armor is thin and highly flexible and this style of armor has become the choice among the premium brands who offer jeans (also used in many riding shirts). For example, REVIT has their very similar Seesmart line and Dainese has Pro-Shape. I really like this style of armor because it shapes around your knee well and works well under slimmer cut jeans.
Note about hip armor: As of this writing, Alpinestars has not offered their optional hip armor to the US market. We checked and the REVIT Seesmart, size RV33-L1 is a good fit for the fabric pocket in the Alpinestars jeans, so take the link below and order for about twenty bucks. We also carry the Dainese Pro-Shape optional hip armor, but it is significantly smaller than the armor pocket in the AS pants.
As I mentioned, the overall fit of these jeans is slim and they have a relatively short waist, which is currently the most popular cut of jeans. Both styles have similar pocket layouts and designs. Both are button close at the waist with a zip fly. The only physical difference I can see is the Merc jean has a horizontal seam behind the knee where the Copper 2 doesn’t. Not sure why the seam is there… it would be better without it as it serves no purpose I can see.
I really like the overall fit, materials, and cut of both these jean syles. As I mentioned in the sizing advice, Alpinestar’s sizing has been “off” from the American market for many years and I’m pleased these new jeans are well aligned with US sizing. :: Paul, 12-10-19
