Alpinestars Air-Flo Textile Pants 3.8 5 14 14
Extremely small fit I tried these on at a local shop before ordering online with revzilla. The fit is insane. I'd normally fall into the Large Tall size category at 6'2" 190lbs, 34" waste, 34" inseam in jeans. The XXL fit me and that is crazy. When I say fit, I mean: I might be able to wear them as an overpant, but most likely just wear some thin shorts underneath. I'm returning them. After sitting on the bike they're too short for my height; they rise up above my boot with my feet on the pegs. I never wore them out, but here are my thoughts: Airflow: excellent. There's mesh everywhere. Protection: ehh. There's enough nylon in the right places. Good enough for summer commuting. Armor: A joke. You might as well cut some pieces off of your mattress cover and slide them into the knee pockets. Fit: EXTREMELY small, but if you pick the right size (2 sizes up) they have a good shape to them and my favorite features were the elastic panels and long boot zippers. I say: steer clear. Not worth the money, alpinestars should chalk this one as a loss. May 27, 2016
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!
