Alpinestars A-10 Air-Flo Pants 4.2 5 29 29
Excellent style and fit! I love these pants! I've worn riding jeans and over pants. Nothing seemed to fit. The pads and protective elements would shift around because regular pants are too baggy. The Alpinestars A-10 Air Flo Pants are fitted to my body, so that the protection stays put. They look amazing too! May 13, 2015
Great protection and flexibility This being my first motorcycle pants i ever wear it feels very weird. Overall the pants look good and fit good . I like the knee and tibia protectors, although they feel weird at first. I would recommend it. May 1, 2015
Summer riding pants Bought these pants to be able to drag an occasional knee on my new Ducati Hypermotard SP. Not all the time, but just in case. ;). Yep old guys can do,it too. Good pant, but I wish they were a bit higher in the back. I don't like to zip jacket for extra movement, so a higher waist would work better. March 30, 2015
A little overpriced Although the pants are nice, I kinda wish I went with the missile leather pants for a little more protection. Regardless I am still happy with them but do wish they had at least one pocket. They have good knee protection, and attach to my astars jacket which is nice. Sizing Is a bit funky. I measure at a 36 waist and 32 inseam. I bought a size 56 which fits snugly enough to keep the armor in place. They do breathe well and should be ok in higher temps. March 23, 2015
Another great alpinestar product Definitely keeps you cooler....that and it makes putting on your leathers so much easier.ll.l December 8, 2014
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

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
Reply to Vladimir Good answer? Yes (0) No (0)
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.

Ivan K 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

Answer this · Send to friends Good question? Yes (0) No (0)
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

matthew c asked: I am 6' 3'' and wear a size 32 jeans. I have a 32 1/2" inseam. Would a size 54 still work? Apr 3, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
Japjit G: I'm about 6'2" with size 38 pants and size 60 fits me perfectly, hopefully this helps. I initially went with a smaller size that didn't fit, if this happens to you don't worry, Revzilla has an awesome RMA policy, just keep all the tags and product packaging and ask to exchange ....These pants are awesome for the summer, good protection and awesome breathability. Apr 4, 2015
Reply to Japjit Good answer? Yes (1) No (0)
John B: Maybe. Go for it. The 54 was a little small for me on a 6' 34/34. Was a bit snug on thighs. It's a tough pant to fit for sure. Go with your jacket size. Apr 3, 2015
Reply to John Good answer? Yes (1) No (0)
Grant C: I am not able to answer other customers questions regarding size, other than to say that I have made many purchases through Revzilla and found their guidance on size to be reliable. They also have a good return policy so the risk is minimal. If you wear boots you have some flexibility with inseam length.
I have been riding with the A-10's in FL for a year. They are comfortable, have a good level of protection and good for hot weather riding (all things considered - they are not air conditioned!!)
