Don't let substandard shorts cut your ride short.

Nothing sours a day ripping enduro lines in your local region's trails faster than chaffing in your even more local nether regions. Alpinestars built the Pathfinder Shorts w/ Inner Shorts to be a multi-layered shield against discomfort, both inside and out. The outside has abrasion resistance to protect you from the occasional crash or grasping branches; the inside has a seamless seat and chamois-equipped lining to help reduce fabric-on-skin friction and saddle-on-cyclist bruising.

  • Ripstop fabric
  • Mesh liner with built-in chamois
  • Mesh ventilation inserts
  • Stretch rear yolk
  • Adjustable waist
  • 2 hand pockets
  • Zippered thigh pocket

How to Measure:
For best results, take measurements over your underwear.
Measure under your arms, around the fullest part of your chest.
Measure around your natural waistline, keeping the tape a bit loose.
Measure around the fullest part of your body at the top of your legs.
Using pants that fit well, measure the crotch seam to the bottom of the leg.

Solid shorts

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: 32

Love the shorts, they fit well aren't too baggy and annoyingly long the only issue I have with them is the chamois. Pretty crappy chamois liner and it doesn't have the silicone lining that keeps them from riding up. Fox chamois liners are the best but the actual A-star Pathfinder shorts are probably my fav. Get the shorts, find another chamois to sub in.

I really like the fit and material feel to these shorts. They have just the right amount of stretch to them, are lightweight, and the waist cinches work well. All 3 pockets are quite deep and large. You can fit quite a bit of gear inside each. I was kind of hoping for a smaller stash pocket for a car key, but that is just being picky. The shorts sit right at your knee, and a bit more baggy than tight, which I would say would pay well between either an all mountain or XC type short. The size seemed true, which I sized up a bit on and utilized the waist cinchs.

While the exterior of the short was great, I found the liner/chamois really uncomfortable anytime I wasn't on the saddle. It seems Alpinestars may have gone on the other side of the spectrum when it comes to liner sizing as the previous pairs of Manual shorts were much smaller.

Either way, the shorts were comfortable while in the saddle and seem quite durable.

Great shorts! I will buy the again!

i have been riding mtn and road bikes for over 25yrs. I have worn all kinds of cycling shorts/bibs over the years. These are some great shorts!!

I ordered them on Monday and received them the next day. I wore them that very day and headed up to a local mtn bike trail. From the moment I put them on I liked the chamois. The fit rivals high dollar road bibs.

I started up the trail and I had to think about my shorts. No pressure points, no hotspots they just fit. I headed up the trail and enjoyed my ride. I noticed after about 1500' of climbing (on a ridged carbon hard tail) that I was so comfortable that I didn't notice my shorts....

I plan on buying a second pair today and letting my other biking buddies know abut them. I love these shorts and can't beehive the fit. Worth every penny.
