Alpinestars Oxygen Air Over Pants 4.3 5 25 25
Its like riding in shorts They were snug when I first got them but after 2 days of riding they stretch to fit a little bit. Order a size larger than you want. Great summer pants. August 15, 2016
Great overpants I'm a new rider and was hesitant about buying overpants as if i was to look doofy while riding or just let alone being there. I commute to work with all my gear on whenever i ride to work, also wear all the gear whenever i ride. but the pants fit perfect, i wear a 30 in jeans and a small fit just fine. feels like it's a bit long while just standing but you can adjust the end of the pants to tighten it around the sneaker/boot, whatever you're wearing. The pants zip up all the way up around the knees which makes it easier to put on and take off on the go which also you can remove without removing your footwear since i wear alpinestar smx-1 boots. while riding, it feels lovely, can get quite hot while sitting at a light and your buttocks can get sweaty but aside from that i feel like it's a wonderful overpants especially for the price and if you have an alpinestar jacket, it zips up to it as well which makes it a wonder as well; as for protection, it has some knee pads and some foam inserts on the hips, i can't speak on how good they are since i haven't went down and really wouldn't like to either.

Good aiflow, but.... These pants are good as far as airflow is concerned. I thought maybe riding with protective gear on my legs would be uncomfortable, but it's very cool and comfortable. When you are moving at speed it it refreshing and you feel secure with the protection for your legs. My only grip is the slider button. Everything about these pants is fine except the slider button for the waist. I'm probably just too dang fat, but that button doesn't do a good job. I probably have extra wide hips for a man, but still, I leaned over and the slider undid itself somehow. I mean cheapo-bigboxstore-noname brand jeans that cost less than $20 come with buttons that don't come undone. Can we get a better button? That's why I recommend that you buy an Alpinestar brand jacket with a waist zipper. You can zip the jacket and the pants together. I don't know if other brands' waist zippers are compatible with Alpinestar pants. My Alpinestars jacket mates perfectly with the pants and keeps them from falling down. Jacket+pants= great protection, and style. May 31, 2016
Great product, good air flow I normally wear a 31/32 pant and the Medium size fits great. I tightened up the waist cinch straps a little and the legs go right down to the bottom of my feet, but not so far as I'm walking on them. The pants offer great protection and good air flow, although I wish the air moved a little better through it. I also wished the pockets were pass through to underneath, but that's a personal preference. I do like that it zips to my Alpinestar jacket as well to provide complete coverage. Overall, great product at a good price. May 10, 2016
Nice summer overpants I wear 33"x30" pants, occasionally squeeze into 32"x30" Levi's. The MED size Oxygen Air Over Pants are a little tough to get buttoned, but otherwise fit snug and comfy. They breathe well and are pretty light. The leg zipper wraps around from the outside of the ankle to the inside of the thigh, which is a little wonky, but still easy to get on and off over riding boots. I love the clean black styling, though I'd take some reflective piping or other subtle visibility if I could get it. April 19, 2016
Gets the job done I use these pants to commute to work, only 30 miles, and have no complaints thus far. Easy to get on and off over my boots and pants. I'm 5'8" and with a 33" waist and I ordered the large knowing I wanted them to be a little bit bigger to fit over my pants. They fit perfect, the knee protection is a tad low walking around obviously, but scoots right into place when I'm riding. April 12, 2016
Large was good fit for typical 32-32 jeans Fits very well over my 32W-32L jeans. Some of the material is mesh so abrasion protection may not be as good as other products, but the convenience of wearing these over my work pants is worth it to me. Air flow is great. Comes with combined knee/shin inserts. There are pockets for hip inserts but no hip inserts are included (there are flimsy pads instead). Zips into my T-Jaws Air jacket at the bottom of the jacket.

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
