Great Value for the price Pants are a little long but ride good. I recently moved to Kauai and have had several opportunities to try them out in the rain. I've gotten to work dry every ride. The full length side zippers make it very easy to get them on and off and they are comfortable on long rides. I'll defiantly be buying another pair when these are ready to retire. July 13, 2016
Alpinestar Products Shine Again! As always - if you're willing to spend a few extra bucks, Alpinestars will make you happy. I am a year-round scooter rider (not a "big boy" bike like the Ducati bros like to remind me) and these pants manage to keep me warm in the coldest Pacific Northwest temperatures that I've encountered; even at highway speeds. I am 6'1, 195 and ordered a size L. I know they're meant to be worn as an overpant, but instead of being super bulky I just wear them over my Under Armor long underwear/base-layer and they're very comfortable (just carry jeans in your pack). I also paired them with the Alpinestar Dusk jacket and I am nice & toasty even after a few hours of riding. PROS: very warm, roomy, blocks all wind, good pockets. CONS: no elastic/velcro ankle strap to keep air from going up your leg, doesn't zip to my Dusk jacket, hard to walk in them without having them sag a little bit. 8/10 overall, would definitely recommend.

Great over pants, a bit on the smaller size These are great, They are waterproof, I took them snowboarding with the knee pads removed. They are a tighter fit then regular over pants, just like my A-Stars jacket. If you are in the military get at least a size larger. I can barely fit a large with my ABUs on. I am 6' 190 lbs if that helps. But they held up to all day on snow and ice without getting torn up, so they seem durable. December 7, 2015
Decent When I first put them on, they seemed to be wayyyy too long. However, with boots on they do not drag at all. Also, when you mount your bike they suddenly become very comfortable. The knee pads slide down to the shin when unmounted. I would not wear these for long after getting off my bike. They feel somewhat like light duty snowpants with the liner in. The outer textile seems very strong. The lack of an adjustable knee is my only complaint with these. I ordered a size medium; I am 5'10" 165 31x31. I would likely fit better in a small, but the medium fits perfectly fine due to the adjustable waist. Per another site, I believe the small and medium are actually the same inseam length at 33.5 or so. I purchased these for cool/cold weather use and they are very warm. I will probably never use them without the liner, which is fine because I would probably want the small if using them without the liner. September 29, 2015
Maybe a bit too oversized? Perspective: By most accounts, I fall under the "average" title. I'm 5ft 10in (178cm), weigh about 150 lbs (68 kgs), and am of average build (neither too flabby nor too athletic). If anything, I might seem "skinny" by north american standards. Sizing: The medium size for this product tends to run a little long in length and a little loose around the waist. With boots on the back of the pant drags ever so slightly as I walk. If the silly thing came with belt loops I'd just cinch them up a little more but in lieu of the sensible option they have ineffective elasticized adjustment bands that do little to keep things up. Protection: Haven't crash-tested the gear (yet?) but it all feels solid. As others have commented, the armour hits mid shin while walking but this corrects itself when perched on the bike. (just be sure to keep your knees bent when you hit the ground, yea?) Features: Waterproofing feels solid. I can't yet comment on the all-season comfort but they don't get sweaty in 80°F (26°C) weather over a pair of shorts. July 25, 2015
Sizing Is Very Interesting On These Overpants... The AlpineStars Drystar Overpants have impressed my with their quality and features. They can be comfortable and keep me warm and dry on those cold mornings. I do have a major gripe with these pants though. I'm 6' 3", weigh 250 lbs, and typically wear a size 40 pant. However when I originally ordered the Drystar Overpants I ordered the XXL because they were the exact length I needed and the website said they should fit my waist no problem, fitment should be a little big due to the product being an OVERPANT!!! So when my XXL's arrived my excitement quickly turned to disappointment when I realized the XXL Overpants wouldn't even come close to fitting my waist. The pants were small to the point that I couldn't even zip them up or button them up, and this was without even trying to wear them over anything! So I exchanged the XXL's I ordered for XXXL Drystars. I can wear the XXXL's as Overpants however it's a tight fit at the very top of the pant. Also the XXXL length is long to the point that I have to roll the pant legs up a little so that they don't drag on the ground. So if your tall like me and where a size 40 pant beware what your getting into. May 11, 2015
In my opinion.. 5 Stars easily. I'm about 5'10 at 190lbs and ordered the XL as I planned on wearing them as over pants as intended.They fit well over jeans or sweats and I never think about the comfort as they never intrude on my riding. I use them to commute to work and also as my weekend riding pants. I couldn't be more happy with the results so far. I live in New Jersey so we get all kinds of weather, I wear them when it's cold, and/or when it's raining and never had a problem with water intrusion or with the cold. It was even snowing on my ride home and they worked flawlessly. overall I rate them 5 stars for the quality at the relatively low price. Your fellow rider Jeff. November 13, 2014
Great Construction, Slightly off fit These pants are leaps and bounds better than my old Joe Rocket ones. My old ones had the zippers bind on the flaps and eventually it destroyed them, so I bought these. The zippers are higher quality, the design is better and they zipping is very smooth. I'm a tall slender build, so the fit is a bit off. The knee armor seems to be just below my knee while walking. Once I'm sitting on the bike, everything seems to be in the right place. These can get pretty hot on a 70+ degree day, but are acceptable while moving. June 2, 2014
