Alpinestars Oxygen Air Over Pants 4.3 5 18 18
Fits me spot on! I bought this pants for commuting and I have to say these pants are great on airflow! I am 5’7”, 30” inseam and a 31 inch waist and the size 46 fits me spot on. I don’t use these as overpants so I cannot comment on having a pair of long pants underneath but I do use gym/workout shorts and they fit with no issues. I use these with a pair of Alpinestars SMX-3 boots and again no issues. With the wide openings when you unzip the bottom of the pants, you can easily put on/remove on the pants with your boots on. I think the only gripe I have with these is the knee armor. It might just be me but the armor on the knees feels a bit out of place and I feel a pressure point but it goes away after I start concentrating on the road more. Overall a great pair of riding pants for commuting or summer/warm weather riding. December 7, 2015
Great for its intended purpose! Great pair of pants...I swear they were tailored just for me (5'10" / 140 lb. / 31.5 in. waist) to fit perfectly over my jeans and AlpineStars leather boots. I only give it an "Average" rating for the "Protection and Durability" category because they are overpants, after all...which are meant to sacrifice a bit of protection everywhere except for the knees (when compared to, say, racing leathers) for the convenience of being able to easily remove them and then go about your business (e.g. when commuting to work).

Good Over Pants for Commuting I commute to work most days on my CBR250R and bought these over pants to keep my work pants (khakis, etc.) clean and for added protection. They work well for this purpose. The pros... they fit me nicely and are not too baggy. I'm 5'11" & 170 lbs. and typically wear 32"x32" jeans. I ordered the over pants in Medium and they fit great. They are easy to put on/take off even with motorcycle boots on. Each leg has a zipper that starts on the outside of the ankle and goes up and over your knee. The over pants connect to my Alpinestars Jaws Perforated Leather and Alpinestars Viper Air jackets with a waist zipper. Temperature-wise, they are comfortable for summertime commuting. I've worn them in the high 90's and while I was still hot the over pants didn't add appreciably to the discomfort. Lastly the knee/shin armor is decent and fits well. The not so good... The hip armor is sad - 1/4" of perforated foam that may take the pain of a hip smack from a 10 to a 9.99. I just ordered a pair of Forcefield's Hip Protectors to replace the foam. The level of abrasion resistance is probably not the greatest. The 600 Denier fabric on the back and sides of the legs does not feel very sturdy. Conclusion... I'll continue wearing these for warm weather commuting but will probably be looking for something more protective with less polyester in the future which will undoubtedly cost more. However, at this price point, the selection of over pants is not great and feel these are one of the better ones available. August 18, 2015
Works for it's purpose I bought these almost specifically for wearing a pair of shorts underneath. Then, when I get to my destination, I can take them off, throw them and my boots in my bag, toss on the flip-flops, and go about my business in comfort. Definitely wouldn't recommend these for anything more than casual riding. Don't think they'd hold up too well in a high-speed dump, but I didn't buy them with that in mind. I think they could be priced a bit less for what they're good for. Ventilation is definitely there. I got these originally when I was living in Arizona. It's hot there if you weren't aware. I'm in Texas now. It's also hot here. These work great for hot day rides. They will be a little baggy in the leg area, but that's to be expected as they are overpants. You'll almost definitely want to use the velcro fasteners at the bottom cuff to prevent them from flapping too much and possibly getting caught. I am about a 33x30, and I got the medium. Waist fits great, even with shorts. Pants seem a little long until you sit on the bike, then everything fits basically where it should, which is how it should be. July 21, 2015
A Solid Protective Summer Pants Option After living with my Alpinestars AST-1WP pants through the fall and winter, it was time to get some summer pants.. so I went with these. They are comfortable and flow a good amount of air. To be honest I'm glad that these have the additional textile pieces.. they don't really restrict airflow too much but I'd rather have the higher denier stuff. Thanks HVB and Revzila for the excellent service and recommendation. May 30, 2015
Good over pants First off, they are not nearly as slim fitting as they look in the picture, kind of baggy, they fit fine over my baggy jeans. I'm 5'7" 150lb and wear 32/32 loose fitting jeans, ordered a medium, waist is snug, and a little long for me. Since they are long, the knee guard is a little low and no adjustment. Easy to get on over riding boots or a pair of Vans. All in all, for what they are, they are good, not uncomfortable riding, and hopefully enough protection. April 21, 2015
Nice Pants I purchased these pants to go over work clothes on my commute. They are easy on/off with the large zips. The knee pad and hips pads work for me. My only complaint is that if you store your pants in less-than-perfect position where the pads are forced to not lay flat they take on that shape. In other words they bend and stay bent until you re-work them into shape. Otherwise great pants for the money. April 20, 2015
Pants are pretty much as expected I've only had these pants for a couple weeks now, but they ended up being exactly how I expected them to be after reading the various reviews. The dual full-length side zips make these pants quite easy to get on and off over boots. I haven't had any problems with the top snaps letting loose like some other reviewers have described. I'm about 5'9" and wear 33/30 jeans. I got the large and they fit me well over jeans. I haven't really had a chance to try them over shorts yet. They may be a bit baggy, but I think they'll be fine. The velcro adjustments for the height of the knee pads are easy to use, but the left one doesn't seem to want to stay quite at the correct height. I rejoined the lower velcro and paid particular attention to lining up the two sides as best as possible. I hope it will make the knee pad stay at the correct height. My other concern will be about comfort when the summer temperatures get into the 80s and 90s. These pants have very little airflow, so they will probably be very hot. I spent a long time going back and forth trying to decide whether to buy these over pants. I am happy with my purchase and would recommend these pants for somebody looking for extra protection and some extra warmth, especially for commute rides. January 5, 2015
