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

RevZilla Store asked: Why did you choose this?
Gerard Jr M: Quality versus price RevZilla always offert the best quality and lower price than other distributors. Mar 19, 2015
CASEY M: good reviews need summer pants Feb 9, 2015
Aaron D: Promised: Good abrasion resistance, adequate breathability for multiple seasons, and good sizing.

I'm looking for safety, comfort and convenience. With pants designed for riding I hope to get all three. The safety promised by Alpinestar has been borne out by the experience of my friends. The comfort has been proven by trying on similar items at stores for twice as much. The convenience? We'll see!

Todd V: protection / airflow Dec 28, 2014
D Y: I needed some overpants that are protective and practical for everyday riding and commuting and high enough quality for road trips. These look like they will do very well. Dec 21, 2014
Dylan F: Because of the protection and airflow qualities and being an overpant, I'll get more abrasion resistance from my jeans underneath and from the overpant itself. Dec 5, 2014
Jonathan B: I commute in a warm climate. Hopefully these will work well over shorts and provide protection while staying reasonably cool. Dec 2, 2014

Leon H: Needed a great pair of pants to match-up with two great Alpinestar Jackets. Feb 15, 2014
jesse r: I thought I would free ball it in these on hot days. Never did for the lack of complete confidence in textile/mesh pants. Plus carpet burn would not be pleasant. They zip to my A* Indy jacket, keep you a bit warm on cooler days, at the same time keeping you cool on hot days. Somewhat. The black absorbs heat from the direct sunshine. They worked great paired with padded riding shorts. Dec 5, 2013
R A: looking for some extra protection over my jeans when I ride to work in the summer. Nov 15, 2013

Jacky C: There's a velcro strap on the ankle which allows you to adjust the circumference of the opening.

Furthermore, the zipper on the leg goes all the way up the knees, so you can leave your boots on as you get in and out of these pants.

Pat V asked: I'm 6 ft tall and have a 36" waist. Would the L or XL fit me better? Oct 9, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Ryan I: I'm 5'10" 200lbs w/ 38" waist and the XL pants are slightly too small around the waist (with shorts/pants on underneath). Also they're a couple inches too long so I would say the XL would be perfect for ya. The sinches on the side will help with the fit as well. Also make sure to get the updated ones with the venting on the shins. I sweat like crazy when the temps are >90 degrees with the older non-vented version. Oct 10, 2014

Geoffrey M: I bought this pant for my son almost two years ago as a gift. He's 6'1' about 195 lbs and athletic with large thighs but a 33 waist. Same question as to best fit L or the bigger in the waist XL. We went XL and it was the right decision. The knee pads fit in the right place and the waist was not too large to adjust to a snug fit.. It's been in constant use and still in great condition.. Oct 10, 2014

Arnold C: I'm 5'10", waist is about 33, I wear an L. I could also wear something under it when its cold. The adjustable waist helps out when I wear something under it or when I don't. In my opinion you should go with XL, I think... Hope it helps. :) Oct 9, 2014

Chad H asked: The description says it will zip in to "selected Alpinestars leather and textile jackets". Will these be compatible with my new Alpinestars GP Plus R jacket? Thanks May 11, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Joel M: I don't have that exact jacket but all their stuff is compatible. They don't do a good job describing it but the "selected" part refers to items with zippers; their wording makes it sound like there are different types of zippers.

If the top says it fits bottoms and the bottoms stay they fit tops, they fit. It's really that simple.

What they should say though is, "Fits all Alpinestars pants that zip together with jackets" and for pants, "Fits all Alpinestars jackets that zip together with pants.

Matthew L: I don't know if it will fit that jacket for sure but I do know that mine came with an extra zipper piece that matches the one on the pants. I used the extra piece and sewed it to my icon overlord jacket so they would work together. May 12, 2014

Mike T asked: I ordered these in 2XL since i wear 40" waist jeans. Unfortunately, they were way too small (to use as over pants). I am wondering if they will be large enough if I bump up to 3XL Revzilla was great with the return and all. I just don't want to keep going back and forth. Are there are other over pants folks would recommend instead? Apr 9, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Colt T: Mike, I think you'd be hard pressed to actually use these as an overpant with a 40" waist, if you have large thighs. I bumped up from an XL to XXL and still have ZERO room in the thighs. They are snug. If I wear anything other than boxer briefs, I legitimately think I'm going to tear them and it's uncomfortable because whatever I'm wearing underneath is scrunched up. I have larger than normal muscular thighs, but they're not HUGE. And for the record, I'm in between 36" and 38" waist jeans, with a 34" inseam. I have no issues with the length, my issues are in the thigh room and waist. If the increase from XXL to 3XL is anything like the increase from XL to XXL (jwhich was relatively minor), I'd probably need a 4XL to use these as an over pant for jeans. I might be able to get away with a 3XL as an over pant for suit pants though. May 7, 2014

Geoffrey M: I purchased this pant as a gift for my son to go with his Alpinestars jacket. I can't answer about size other than, in his case at 6' 1", 205 lbs and athletic build similar to the demonstrator in the video, the XL was an excellent fit. However, as a vented overpant that has been in almost daily use for over a year, he's been very happy with the quality, comfort and durability of the pant and would definitely purchase this pant again.

Matt D asked: I am pretty thin and tall. Usually wear a 31x32 or 31x34 size for jeans. Do you think a medium will fit? Sep 17, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Andrew L: I'm 6'2" and generally wear a 33/34-34 jeans. I went with the large since I wear them as overpants and the waist is perfect. The length on them is good but the knee armor is a little high on me so it rides up over my knee on longer rides. I ride an SV650 on stock pegs so take that for what it's worth with respect to leg position. Sep 17, 2013
