A-Stars A-10 Air-Flo pants crash tested on 2nd wearing!!
I bought these pants from the Revzilla showroom in Phiadelphia (staff was very helpful) since I wanted to try them on. Size 58 fit my 34 inch inseam/225 lbs/6'3" very comfortably. On riding, the air flow was excellent. 2nd time out with the pants, a car turned directly across my path while leaned over pretty far on my RC8R. Tapped the Brembo Monoblocs and...woosh - there goes the front end (rider error). Went down hard at about 50 mph. Bounced, tumbled and slid. Banged my scapula/rear ribs pretty hard (will review jacket separately). Pant were shredded (check photos) but I has zero - nothing - nada from the waist down. No bruising, soreness, scrapes, nothing. And I hit the road HARD. Check out the photos of the pants. They're toast but they did the job beautifully which is to protect me. And they did that is spades as well as being very comfortable. Negatives? Would like to have one small zippered pocket for convenience. If you're looking for more protection for street riding in a sporting manner short of leather and need a nice flow of air to keep cool, check out the A-Stars A-10 Air-Flo - you won't be sorry. Crash tested and PASSED!

A10 vs Dainese New Air Drake Comparison
I just picked these pants up to replace my Dainese New Air Drake textile pants. I've been wearing the Drakes for the last two years so I will compare the two since they are competing products and I think anyone looking for this style of pants will look at both of these.

I am 5'6", 30ish inch waist, with skinny legs. I think my inseam is 28-29". I have both pants in a 46.

The A10s definitely have tight calves like others have mentioned. I have to pull the pants down a little to zip the calves. They're comfortable once zipped and I expect them to maybe stretch a tiny bit based on other reviews. The length is also a bit short. The legs stop right at my ankle. Ultimately these are benefits as it is clear these pants are made to be worn with full length boots which is what I wear.

The Air Drakes have more room in the calves but maybe slightly less room in the thighs. This means you have to fold the lower leg over on itself if you want to tuck them into boots. However, the legs aren't wide enough to fit over full length boots. The legs are also longer. Compared to the A10's, the legs will drag on the floor when wearing socks. However, it also means you can wear these over short boots.

Knee and shin protection for both pants is roughly equal. The Air Drake pads cup my knee a little better. The A10 pads are slightly larger which is probably a good thing.

Both pants have dense foam around the hips. The Air Drakes feel like they have a little better coverage in this area.

The A10s have a little ribbed padding piece under your tailbone. It's hard to tell if it will offer any significant protection though I would rather not find out. It doesn't seem to affect comfort when riding.

The A10s have much needed stretch panels along the lower back and above the knees. This is an area where the Drakes are lacking as they are definitely tight in the knees and you can feel the back of the pant tighten when in a tuck. The restrictive knees in the Drake also make it harder to hang off the bike. The A10s also have velcro patches on the knee for sliders. This is one of the primary reasons I am switching to the A10s over the Drakes.

Both pants are equally snug in the crotch area which is through no fault of my own. You can feel this restriction when hanging off the bike. More room or stretch panels would be nice to have.

The Drakes have a tighter waist than the A10s. The A10 waist is elastic and much more comfortable. However, the Drakes have a rise built into the back of the pants that the A10s do not. If you don't zip your jacket to the pants then you're going to have a gap when riding.

The A10s obviously flow more air then the Drakes. The A10 textile is a better comparison when it comes to air flow. Dainese just released a mesh version of the Drake so that is a better comparison to the A10 air. It looks like it has more mesh than the A10s so it should flow better but may also offer less abrasion protection. I would expect the alternative versions of either pant to fit the same.

The textile material used in the Air Drakes feels studier than that in the A10s so it seems like they may offer better abrasion resistance.

Both pants have mesh lining inside of them.

The Air Drakes also have two side and one rear pocket. The A10s have no pockets. I am indifferent to having pockets in my riding pants but I can see how it could be useful to others.

Both prices are about the same for these pants which isn't too unreasonable. On one hand, you can get nice leather pants for not a whole lot more than what you will pay for these. On the other hand, decent riding jeans cost about the same but are inferior in protection and in the features they offer.

My reason for switching to the A10s is to have more air flow and because the Air Drakes are too restrictive in the knees, both when riding and when hanging off the bike.

Also, as with any Alpinestar product, their name and logo is plastered everywhere. It looks tacky and I don't like being a walking billboard for their company. I removed the rubber Astar logo on the knees by cutting out the stitching. They look much better and you could never tell a logo was sewn in there. I also used a black fabric dye pen to black out the Alpinestars name on the velcro shin patches.

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. :((

sizing is key!
So we all read these run small. I will use myself as a prime example of why I selected the size I did. I am 5-7” tall, 223lb with athletic build, 38” US waist with 30” inseam. I have an endomorph body frame combined with me working out means I have a dominant lowerbody. What I did was take my jeans waist size and add 20. That puts me at 58 EURO. For the average guy, I suggest you stick with adding 18 to your waist. For the skinny/staving folks, I would stick with Alpinestars sizing chart. As always, make sure to call Revzilla and see what they recommend first!

I test fitted the 58 EURO and it was a perfect fit minus the inseam. Me being a short rider, there is no way around it so I’ll suck it up. 58 Euro puts me at a 41” waist and there is plenty room leftover in the waist line. The thigh and calf area however were spot on. The rear end WILL sag if you do not zip this up with your motorcycle jacket. As mentioned, you will mimic a plumber without these pants zipped up. I can see myself squeezing into a EURO 56 but I wanted a more relaxed fit than a tight fit for my commute. I can pinch just enough material on anywhere of the pant using my thumb and index finger. Everything fits in place and I only wish I was taller then it would be a perfect fit to compensate my short inseam length. As I was trying these on, I ran a small fan to test its “air flo” title. Let me say with the personal sized fan I was able to feel the air flow through the pants all around. I can only imagine flowing tremendous air while riding. The hip padding is a nice touch. Combined with knee protection, this makes the A* Air-Flo pants a nice touch. I replaced my jean/knee armor combo with these pants and glad I did. I recommend this product if you have the funds for it. Oh yeah, the inseam stops at the ankle bone so these are meant to go with full boots. If you're a tall rider and plan to run full race boots, there shouldn't be any worries. It's us shorter folks who will find sizing the biggest challenge ;)

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.

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..

Excellent Track or 'Sport' gear
The A 10 is excellent.
Fit: I'm 5'10, 185lbs,, ~31/32 inseam, muscular, wear 34 jeans and 36 measure around navel. Euro size 54 is perfect fit for me. Leg length is not a concern with track boots or any high riding boot.
Weight, Comfort: A 10s are relatively light weight (compared to leather, duh) and very comfortable on and off the bike. In prep for track I spent a few three hour rides in these at 90+ degrees and they are cool while moving. In traffic, yes, they get a bit hot. At Track, 7 a.m. - 5.p.m., 80 to 90 degrees. they were great; comfort, some air flow while riding and okay walking around the pits.
Protection: Strong layers of aramid and denier (sp?), well placed armor in hips side of thighs, cixcix and heavy knee shin armor. No crashes, thankfully. But my bet is they'll hold up and protect in a bad slide or low impact high-side. I'm completely confident.
Overall: A bit pricy but I recommend A 10s. When you get you hands on them, and put them on, you'll feel the quality, comfort and protection.

Great pants for any type of riding
Knee and Shin protection is great and removable.
I removed the tibia protection to slip the pants inside my boots which already protect the same area. The pants are great comfortable in 30 to 90 deg weather for me atleast (really depends on the person) Will get a little damp if you get caught in rain for about 30 miles and was fine. Anything further or really heavy and I would have been soaked. Definitely suggested for nice days and could easily get away with a chance of rain.

Nice pants and a very good value
Pro's - These are a great pant mated to an alpinestars jacket. I have mine with a stunt. They feel rugged... for a material pant.. and have very good protection. I found them to be VERY confortable on and off the bike. Do not have a loose bunched up look when walking around. The knee slider patches are great. I wear pucks and they get used "supermotard" and do track days every once in a while and its a great feature.

Cons - Like most pants when not connected to a jacket they feel like they are falling down in the back. Its just the correct cut for riding. They are not nor will not fall down but it feels that way. You get used to it quickly. Its not really a problem. When you put them on your foot will somethings catch the armor in the knee. You just need to go a little easy and you just need to get them settled in on your knee when on. Then you do not need to touch it again.

the only non leater race style pants
I try to avoid leather as much as I can ( animals sake) and tese are the only non leather race style pants you can get as that is the style like.
The fit was very tight around calfs and backs of the knees at the start but after a month of weekend rides they are perfectfit now.I live in Northern Ireland so I only use these and the T-RC1 jacket between April and October as it can get a bit cold in the winter and the pants let the water in straight away, but I only use the bike in the dry.
I hope I can get these in the future when I need new ones or I will be lost for any race style clothes.
Apart from my boots and helmet everything is Alpinestars as they are such good quality and tick every box for me.

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?
Samantha S on Sep 5, 2013
BEST ANSWER: 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.
Would the zipper connection for these pants connect with the Alpinestars Jaws perforated leather jacket?
A shopper on Aug 10, 2013
BEST ANSWER: hi good day, it is correct, you can connect the pant with jacket
Removable knee slider covers. Does that mean you can attach actual a-stars knee sliders?
Kasper S on Sep 18, 2013
BEST ANSWER: Yes you can attach any Velcro slider to the pants.
I want to sew in the zipper into my non Alpinestar jacket. If it doesn't come with it is there any way to buy the zipper seperately?
A shopper on Dec 13, 2011
BEST ANSWER: Typically they do, but if for some reason it is missing, you should be able to source one directly from Alpinestars at 310.891.0222.
Will this work as an overpant? I'll usually be wearing jeans or cargo shorts if anyone has tried it
John Michael H on May 27, 2016
BEST ANSWER: No. These pants are snug fit and will not allow for any pants underneath. When stationary these pants keep in a lot of heat; however once you are riding they are quite comfortable. My only complaint is I wish they had an air flow pocket on the thighs so that it's cooler to wear when stationary.
How would these pants fit with a SMX-1 boot? Are they meant to be worn with a shoe or high boot?
Ivan K on Apr 12, 2014
BEST ANSWER: 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.

Does it have a waterproof liner?
A shopper on Oct 10, 2013
BEST ANSWER: 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 :)
Do they have any hip protection?
Brandon N on May 3, 2016
BEST ANSWER: Yes. A measurement through the fabric gives me a guess of 1/4" pads that are smallish and on the hips. There's also smallish 1/4" pads on the buttocks and the outside thigh. The knee padding is fairly sizeable.
I bought it last month.
But how do we wash clean it ?
Can we remove all protectors ?
Soumendra J on Sep 24, 2015
BEST ANSWER: I wash mine occasionally in the washing machine. All the protectors are removable. I try to wash them by themselves or with my jacket in cold water. I lay it out to dry.
I am 6' 3'' and wear a size 32 jeans. I have a 32 1/2" inseam. Would a size 54 still work?
matthew c on Apr 3, 2015
BEST ANSWER: 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.
