Alpinestars A-10 Air-Flo Pants 4.2 5 43 43
Comfortable Protection at its Best! Ordered these after deciding to graduate from jeans to armored pants following a collision with a deer. Other Revzilla reviews suggested ordering a size larger than what I typically wear and I'm glad I did! Usually wear a 34/32 and the size 54 fits great. The knee and shin protection is substantial. The knee inserts move around some when first putting these on but once they're on and adjusted I've got no complaints. Good investment and safety upgrade for the money! August 16, 2016
Great Pants This are great pants for summer, a lot of air flow while riding. I had an accident in these pants they did the job! Personally prefer mesh material over leather, so when I was sliding on road and then grass in accident, I just slid and stopped, nothing ripped. Threw them in washer after accident, came out like new. May 31, 2016
Look Great and do provide some well needed Air flow I live in Dubai and in the summer the temperature here gets to around 50 Degrees Celsius (Around 130 Fahrenheit) so some riding pants that increased the airflow to my crown jewels are an absolute must. I have ridden a few times in them now and i can tell the difference between these and when i was wearing jeans. I also like the added protection around the knee, shin and hips as it made me feel a lot safer on the roads here where people drive like they are possessed! I would definitely recommend them if you live in a hot region and want to keep your plums a little cooler. May 26, 2016
Comfortable with great style Excellent fit with great style, good protection and comfort. Provides very good air flow to keep you cool in warm weather. I went up in size as my measurements were on the high size on the chart. April 26, 2016
Great air flow They are great for California weather. I have leathers but I wear the A-10 Air Flow pants almost every time. April 26, 2016
Poor design if you wear motorcycle boots I got these after reading the great reviews on here but am very disappointed with them as they suffer from a fundamentally flawed design at the bottom of the pant. The fit is small so I had to return to get the next two sizes up (excellent and fast exchange - thank you Revzilla). The replacements fitted well and were very comfortable with impressive padding, armour and protection. But this last point (armour and protection) are also the pants undoing. The bottom of the pants are so thick with material, inner lining and foam padding I can't get any of my motorcycle boots on over them... I have three different types of Sidi boots (Agueda's (motoX), Discovery's (commuter rain boots) and a pair of ST Air race boots) and I couldn't even get the small shaft race boots on over these pants. The other two wouldn't go on even if I extended the straps and buckles out as far as they'd go. I removed the shin guards from the pants to try and help, but the pants still have non-removable foam built into them that goes right down to the ankle. This - coupled with a lot of fabric and lining material means they are simply too thick/bulky to get any pair of boots that are more than ankle high on over them. Very surprised Alpinestars have designed these so badly. Although I don't note this problem in any other reviews so not sure if it's just me - or I'm the only one that tried to get boots on over these. I will reluctantly be returning them. January 7, 2016
Great Pants I'm at work so I can't remember exactly what size I bought, but all I can say is the Alpinestar sizing chart was pretty much spot on for me. They fit perfect upon arrival. Great air flow, which is one of the reasons I bought these. One complaint is the lack of some front pocket. Not really needed, but I'm constantly searching for one where a jeans pocket would normally be. The other complaint is that the included shin pads didn't really want to work with my boots. My boots offer some shin protection, but they would push the shin guards up into the knee pads and things quickly became very uncomfortable. Once the shin pads were removed, the pants were extremely comfortable. I can't speak to how they will hold up in a crash, but the padding seems decent. Hope I never find out. Overall, I gave a 4 because of the couple of issues that I mentioned. However, beyond that, these are pretty much perfect for me. I'd definitely buy again. December 14, 2015
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. August 28, 2015
