Alpinestars Air-Flo Textile Pants 3.9 5 13 13
Very comfortable and great air flow but not much protection The pants have great airflow and are super comfortable but do not offer much preotwction. The pants have an adjustable waist that comes in handy if you are wearing basketball shorts or sweatpants underneath. The sides also zip all the way up to the knee although im not sure why. Good pants if it is a hot summer day and just cruising around the city. Not wheeling. Lol July 16, 2015
Good for warm weather riding Looks great, fits great, solid quality for a good price. Not sure about the knee protection and there's no hip protection at all. Decent airflow, better than jeans. I wear 34 x 32 jeans and the size large fits perfectly. Easy in and out with full zips. No cuff adjustment to snug up around boots but I suppose that helps the airflow. June 21, 2014
Pretty good, not perfect Overall, these pants are pretty good. They fit my 5'9", 155 lb frame pretty well in a size M, with room to fit my knee pads and protection shorts. They are fairly fitted, becoming more snug towards the bottom. They are advertised as having a lot of air flow, but I only rate them as moderate. The fact that I always wear pads underneath does have an effect on the airflow. If you plan to run raw underneath, you should be just fine. I do noticed airflow in my more sensitive areas and inner thighs, which are not padded up. They do flow considerably more air than my kevlar jeans (with the same pads underneath), so they do fulfill their intended purpose. Just don't expect airflow comparable to wearing a mesh jacket, and you won't be disappointed. December 10, 2013
well made materials Pants fit good and look to be made to hold up to average riding. The fit is like most pants with knee pads low until sitting on bike. I have 32 inseam and they fit great, zippered legs work well for fitting over boots. Protection is average but looks like it could be upgraded if I choose too. like any pant , they will be warm when stopped in 90 plus heat. September 5, 2013
Good but bad knee protection Everything is excellent on this pants except for the knee protection... It's a joke. But it is removable. August 5, 2013
great overall good pants!! even tough the weather is really hot over here I had no problems with the pants the air flow was great, the pants run small and the knew pads are low, I wish it had the zipper to zip it to the jacket, good price also. overall I'll recommend this product July 12, 2013
Disappointing product from legendary Alpinestars Pros: 1. Material quality - I really believe it won't rip that easily 2. Boot accessibility - zipper opens all the way up Cons: 1. Protection - will probably keep your skin intact when sliding on the tarmac but there're no effective impact protection at all for the hip, knee and shin areas. 2. Sizing - waist measurement should never be dependant upon a person's height; a fully adjustable waist would be perfect BOTTOM LINE: Alpinestars R&D team could've done way better... it's an absolutely disappointing, half-cooked product! July 8, 2013
You get what you pay for. I was very excited to get these in and was so disappointed with them. I did not like the fit of these pants and there's basically no protection in them. I would imagine a good pair of jeans would offer the same amount of protection, which isn't saying a lot. The knee armor (more like foam padding) sat very low and I don't think they will offer much impact protection in the even of a crash. I quickly exchanged these for Dainese New Drake pants and while those are $100 more, they are easily worth it. The Dainese pants are very nice fitting, have better materials thoughout, and has great protection in all the right areas. November 6, 2012

Allen C: Good pants for the price, they don't offer the best protection but you get what you paid for. However they do hold up to their name, they offer amazing airflow, not once has my legs gotten sticky with sweat. The air just keeps on coming in. Very comfortable as well, no restraints anywhere.

A shopper asked: Are there pockets to add knee and hip armour to these pants? Feb 2, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Rick P: No. The pants come with temper foam in the knees, they are short and wide (5"x7"). I had a seemstress install larger pockets in the knees for the Alpinestars Smart Guard kit (7"W x 12"L). She did have to sew through the whole pant, including the lining, well worth the upgrade. There is no hip armor option as there is a zipper on the hip area. I have Icon armored shorts, they are a good option. These pants are light weight for summer, not race level protection. All this gear is generically sized and varies from brand to brand, a little bit of customizing is required for better fitment and protection. Good luck. Feb 3, 2014

Rick P: Yes on the knee pockets and no on the hip pockets. However, the pants come with temper foam that is short and wide (5L x 7W), the pocket are the same. I had a seemstress install pockets for the Alpinstars Smart Guard knee armor kit (7W x 12L). She did have to sew through the outer shell and the liner, but well worth it for the upgarde. More comfortable and hardly noticeable. There is a zipper in the hip area, so a pocket there was not an option. I have the Icon armored short, a good low profile option. Feb 3, 2014

A S: There is pockets for Knee armour. They come with cheap foam knee inserts. Definitely need to upgrade to CE standard. No pockets for hip armour. Fit is quite roomy. General quality is excellent. Feb 3, 2014

SP 634910688 i: For the knee yes and it comes with a thin pad .. And None for hip .. But I recommend you go for the forcefield armor, perfect and comfy Feb 2, 2014

A shopper asked: I'm 184 cm tall, waist 104 cm and hip is 112 cm. What size of this pants is fitted for me? May 14, 2012
Answer this · Send to friends Good question? Yes (0) No (0)
RevZilla: Based on your height of 6 feet and .5 inches (184cm), your waist of 40.9 inches (104cm) and your hip dimension of 44.1 inches (112cm) we would recommend the size 4XL, which is not currently being produced for this particular pant. These pants are offered in sizes XS-3XL. However, Alpinestars does offer a few other pants in a 4XL. May 17, 2012

Colin F asked: Are the XL's in this pant any longer than the Large size? Im 6'3" and found the L to be a bit too short. Prefer to have pants that do not rise up when seated on bike. Jan 30, 2014

vlad k: Hi Colin,
I bought the L in these pants and had the same problem, I'm 6'2 and when standing all good, but riding was different as the knee pads crept past my knees. Would like to size up to see how the length would be. As I'm in Australia I don't have the option to try another size. Good luck

Colin F: The knee foam is removable and should be replaced. Its crap, really. Im sure Alpinestars makes knee guards for it but I use knee guards that strap directly to my leg to avoid the shifting. Jan 30, 2014
