Alpinestars A-10 Air-Flo Pants 4.2 5 24 24
Great Overall Pants First off, these pants do run small and fit snug as most "track" styled pants do. I am 5' 7" about 130ibl with an athletic build (~5-8%bf). These are the epitome of an "European" cut. It is hard to find pants that fit my build in general, much less riding pants. I am currently wearing a 44 US / 60 EUR and they fit like a glove. They seem substantial and as another reviewer said will stand up in a crash. I expect them to do their job but be a one use type of deal just like any textile gear. The knee and shin protection is great and placement is dead on when riding. The knees have a jelly/foam texture over the armor for comfort and there are no pinch points. The first ride I took in these was about 50mi and they were comfortable but after my second ride breaking them in they felt perfect. They flow air pretty well and are suited for Southern California weather. They can get a bit chilly in DEC - FEB but any other month are just the ticket to avoid a swampy underside, if you catch my drift. I would suggest taking the shin armor out if you want to tuck these into a full boot; if you want to wear them stock then go with a shorter style boot. All in all I am very pleased with this purchase and would advise anyone who is a smaller build to try them out. February 5, 2014
Torn easily I am quite disappointed with these pants, since I only had them for 6 months when they got torn in between my legs. Never have I fallen in them or done anything awkward. I guess, just walking in them could have done the tear. Warranty claim was also refused. I would expect better from quite pricy product and a firm like Alpinestars. :(( December 17, 2013
Love em! The first pair i ordered where way too small bc i have long legs. but with a simple and easy return i got the new ones and love them! they fit snug with enough room i wear basketball shorts underneath and i sure i could (tightly) wear jeans. I love the knee and shin armor and the hip, thigh, and buttox armor could be thicker but i trust it! they look dang nice and do not ride up and crush the family jewels if you know what i mean. The air flow isnt great but i have yet to sweat and over heat while riding in them. Sitting still gets a little hot but thats expected. October 14, 2013
GREAT great product and great for warm weather. the fit is a little tight but does stretch over time to fit more comfortably July 23, 2013
Solid summer riding pants Great option in lieu of leathers for summer time in Florida and a perfect match to the Air Flow Jacket. Great protection and very comfortable riding positions on my Panigale and Diavel. Sizing: I am 5'11, 190lbs, 36 waist, 44 chest, I ordered a size 54 and the fit is absolutley perfect. My only concern is the attachment zipper for the jacket is a standard clothing (small and does not feel rugged) size so I hope it holds up.. June 24, 2013
Highly ventilated, all textile pants ready for knee pucks, but the fit could be better. They're the only high airflow, all textile pants that come set up for knee pucks, but the loose waist and wimpy jacket-attachment zipper make me fear getting caught with my pants down. These pants are very comfortable. I'm actually planning on doing a 900 mile weekend trip in them. However, part of what makes them comfortable is that the elasticated waist is quite loose, so much so that they slide down while walking if my jacket isn't zipped into them. And there is no waist adjustment. I had to go with a size 54 because of my height (6'3"). Any size smaller and my bare legs would be showing out of my boot while in riding position, and any size larger I'd be able to fit a pillion in the waist with me. I wish I could be reassured by the jacket-attachment zipper, and it does hold the pants up just fine, but in a crash I'm afraid the wimpy little teeth would give way and I'd grind my behind across the asphalt. The thighs, knees, and lower legs fit nice and snug, and although I haven't had the pleasure of dragging knee in them, I'm confident that a puck will stay in place during more aggressive riding.

Good summer pant Wanted some decent lower protection for hot summer mountain riding. The A-10 Air-Flo's draft a lot of air when moving, and seem fine up to about 85F, but do get hot when just standing around. Seem to have decent protection but light compared to the GP-Plus leather or Track pant. Go 1-2 sizes larger compared to your normal pant. I'm 6'2" 175lbs, 32/33 waist with a 35" inseam and the EUR 52 - USA 36 fit snug and a little short. Knee pads feel fine and the pant material does not feel slippery on a stock R1 seat. June 10, 2013
Overall Great Pants I'm 6' & 170lbs with a slender build and a traditional jeans size of 32. I started with the 50s and they were too short in the upper leg such that the kneepad was very constricting. I moved up to the 52s and I could tell that they were noticeably larger. The waist was still fine, probably a bit more comfortable than the 50s and the leg length was good. I think the kneepads will take some getting used to, but I did 150mi right out of the box with these. Airflow was great, zip into the jacket is a nice feature, and I feel very well protected with the padding. Overall, I'd recommend the pants, but sizing is key. May 20, 2013

RevZilla Store asked: Why did you choose this?
Steve F: Wanted an aggressive pant, but not leather, to go with my Alpinestars Viper jacket in summer. These are very comfortable and look pretty good, too. Mar 12, 2014

Samantha S asked: What boots are meant to be worn with these pants? I have a pair of SMX-5's but the shin protector will not fit inside of the boots, and the pants will not fit over the boots. I also have a pair of SMX-1's and they look completely goofy with these pants. What are these pants meant to be worn with? Sep 5, 2013

Neil A: I wear the A-10 pant (as-shipped with the shin protector inserted) with lo-boots (Dionese Dino CB2).

To wear the A-10 pant with boots that cover the shin (SMX-1, i believe cover the shin) I remove the shin guards from the pants... velcro at the bottom and just above the pocket for the guard hold it in. I then wear the A-10 with SMX-Plus boots. The fit is snug but the boot allows sufficient adjustment to make it comfortable.

Japjit G: I love these pants, and I understand your issue... I personally wear a low profile SIDI boot with these pants with the boot being worn over the pants, I personally find the ankle zip up area to fit very tightly and it would be nearly impossible to fit a boot underneath it... Hope this helps (the SIDI boots go well with these pants) Sep 5, 2013

Vladimir B: This pants are perfect to use with full protection boots and should fit your SMX-5. I use em with my Dainese Torque RS Out and there's plenty of space for the pants. Maybe it's because my boots got the calf adjuster, but anyway ? the part of the pants that go into the boot is really thin. Sep 7, 2013

Sebastian G: I'm not entirely sure what boots they are designed for but I personally wear them with my SMX-1s. It may look goofy but they do their job perfectly which is to keep you safe. If you are worried about impressing other people and how you look, you are riding for the wrong reasons. Sep 10, 2013

Sergey M: Hi there.
I have SMX Plus and they fit perfect to A-10 pants.
When I wear SMX Plus with jeans, it's goofy. But with A-10 pants inside it's tight fine.

PETRO- Steven S: Samantha this pants are neant yo wear with an underneath boot. The pants do come a little small in size. Though these pants feel great lost of airflow and are ment to wear tight Sep 5, 2013
Todd T: These pants are designed to be worn on the inside of boots. Alpinestars have an excellent selection of sport bike boots and they go great with these pants.

A S asked: How would these pants fit with a SMX-1 boot? Are they meant to be worn with a shoe or high boot? Apr 12, 2014

Luc M: Works perfect with the SMX Apr 12, 2014
Reply to Luc Good answer? Yes (1) No (0)
Jon B: I believe the SMX-1 boot is a low cut from Alpinestars. These pants are clearly made to be worn inside a high boot. I wear a pair of SIDI ST Air boots and they fit perfectly tucked in. I would NEVER wear these pants in a low cut shoe/boot.

Hope this helps.

Tommy N: Although these were meant to go with high top style boots, these will work with SMX-1's if your a short stalky build like myself. I am 5-6" height and wore a size US38 for reference. In my opinion, if you're 5-10" or taller, some of your ankle may be exposed with a short boot. Apr 13, 2014
Reply to Tommy Good answer? Yes (0) No (0)
John M: I believe they are designed for boot wear only as they are not long enough for shoes nor should you wear anything below the ankle. When worn inside of boot yes they work very well with SMX-1 Boots and are great warm to moderate weather riding pants. Apr 13, 2014

A shopper asked: Does it have a waterproof liner? Oct 10, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Japjit G: These pant don't have any liner, or not anything you can remove anyway. Although if it's water you're worried about, I wouldn't worry with these pants. I personally also have the matching jacket that zips together with these pants and I've been caught in the rain a few times where this gear. The outer shell of these pants will repel water very nicely. Last time I was in a down pour the clothes I was wearing underneath were bone dry. I highly recommend these pants for warm/hot weather riding. The allow massive air flow to keep you cooled down... hope this answers your question :) Oct 10, 2013

Luc M: These pants come with both halves of the connecting zipper...My wife sewn the free half to my Dainese Air jacket since the Dainese one was not compatible. My guess is that it should fit, my Dainese pants fit with my two jackets... Aug 12, 2013
