Alpinestars Oxygen Air Overpants 4.2 5 26 26
Upgrade from jeans already!!! Upgraded to these from a lifelong use of jeans as riding pants. I wish I did it sooner. They are more comfortable flow better air and have much better protection than any jeans. I wear shorts underneath in warm weather, long underwear with sweats or jeans in cold weather. They are not an overland but the work great as both. I bought my true size but they have the room to wear a layer underneath. Just love these things an will never be without these ever again. Get them!!! March 30, 2015
Not a lot of air, but well-made These are my first overpants, and I'm a relatively new rider, so I have nothing else to compare them to. I'm a size 33/32, and went with the Large. They are a bit too long, so they bunch up a little at my boots, but the waist is about right, and they fit well over shorts or pants. The build quality is good, and they seem durable. No issues with the zippers, though the velcro on the leg openings are already getting a bit frayed after several months of use. They zip on and off easily enough, and I appreciate the exterior zippered pockets. The knee armor seems to sit in approximately the correct place while riding, but when standing, it falls just below my knees and the top of the (fairly inflexible) armor hits the bottom of my knee cap when walking, which is slightly uncomfortable, but nothing serious. The armor is fairly hard, and shifts around a bit, but it's not terrible. The rest of the padding is minimal, but probably better than nothing. My only real complaint is the relative lack of airflow. Only the thigh area has any mesh, which seems odd, since that location doesn't get a lot of direct wind in the sitting position. If I ever have to stand on the pegs, I notice a good amount of air passing through for a moment. otherwise they're fairly windproof, and I might be looking for something else to use in the 80-90 degree temperatures soon.

Baggy as These pants are baggy as. They look tapered on the pic however they are not. December 22, 2014
Fantastic pants great to ride with good airflow Fantastic pants great to ride with good airflow And true to size also no need to order larger December 15, 2014
Almost like riding commando Had these for two weeks and 400 miles, and they are great overpants! Mesh allows plenty of air, but isn't see-through. Leg zips open up wider than the Cookie Monster for dressing with boots on. Front pockets have zip closures. There are no rear pockets. Zipper for jacket connection extends from hip to hip, not just 6 inches across the back. Knee protection feels like foam pads, but is CE-rated and stays where it should when riding. There are some ephemeral hip pads, but they're not advertised, so I see them as 'extras', and won't pass judgment. They're black, though, and have very tiny reflective piping and no hi-vis patches. I've got 4x4 reflective patches on order that I'll sew on either side of the cuff zipper. (Wish the pants came in white or hi-vis lime/yellow.) Style? Some. The A-stars logo is prominent; maybe that's important to you. They fit and feel like my bell bottom jeans from years past. Comfort? Lots. I'm 5-11, 190 lbs, and the size chart found the right size. Legs are a little long for walking, but precisely right for riding -- which is the idea, right? Protection? Mesh is heavy-duty; kneepads are CE and stay in the correct position ... I'll guess protection will be fine. Air flow? Mega. Worn these over blue jeans, canvas shorts, and spandex running tights. When summer comes around, I'll consider wearing them over boxers. Features? Nothing other than what's listed above. Overpant pockets do NOT allow access to "underpant" pockets so transfer wallet, keys, phone, etc somewhere else. (Shouldn't be carrying hard objects against your body anyway, IMHO.) Recommend? Yes. If you want a no-frills protective overpant that ventilates like crazy, this is what you're looking for.

Solid value but order at least 1 size larger than normal First off, it took me a few attempts to get the right size in these pants. I've been losing weight recently, and am now somewhere between a 36 & 38 waist in jeans. I'd think that would put me in an XL. The XL's wouldn't even go past my knees they were so tight. I returned them for the XXL, dubious that even those would fit, and ready to potentially try 3XL. The XXL's ended up fitting, but just barely. They have plenty of room through the calf, and are perfect length wise, I'm 6'4" and wear 34" inseam jeans. These feel long, until you sit on a sport bike in normal position and then the length ends up being just about perfect for me. It puts the knee pads in the perfect position, and the length just covers to the correct length on riding boots. There are at least 2 usable pockets (I haven't checked to see if there are any more hidden somewhere, I haven't needed to). Padding is good, and they seem like they'd make a pretty big difference in a crash, though I hope to never find out. I did have a friend who crashed while wearing the same pants this weekend, and they held up, although it was a relatively tame crash as far as those go (low speed, front impact). These seem to have saved his shin though, as the shin pad was dislodged and had some scratches in that position on the pants. I have yet to ride with these in anything warmer than 65 degree weather. I have a feeling though they will be QUITE warm in anything above 75, but then again, I get hot incredibly easily. I don't think they'll be worse than the kevlar jeans I have, but probably about the same. May 7, 2014
Good pants I've been wearing these pants every day on my 20 min commute to work over a pair of jeans. I've only had them for about two months and they've worked great so far. The weather has been cooler and hasn't broken 70 degrees. Over a pair of jeans they keep the chill out but I can see how they might get a little too warm once the temp reaches the 80s and higher. Overall I am glad I purchased these pants. They are comfortable and I feel good with a little more protection with the knee pads. February 11, 2014
Good Fit I bought these a size small because they were not to be used as an overpant as recommended by the video. Things l like: Nice fit without a baggy feel. Good upper ventilation where the mesh is located. 2 good size pockets up front. Things I don't like: Not much lower leg ventilation, will have to slightly unzip the bottom when it gets warmer. Hip padding is weak. Overall I would recommend the product however I think it is slightly overpriced for what you get, $150 would be a better price point for these pants. As always great shipping, received item in 2 days. November 18, 2013
