Hot pants! I wear these over my underwear and under my regular jeans. It makes your balls sweat. I don't realize how sweaty it gets down there until I take it off and my underwear is damp. Other than that, it fits comfortably. I can't comment on the protection and hope I never have to find out if it is truly effective. September 1, 2015
Cold weather only. Got these for extra protection during commuting. They are really sweaty in any temperature above 50F and will only be using them in the early Spring, late Fall, or for winter sports. April 20, 2015
Great product Fit well, unfortunately too cold to wear yet...... March 2, 2015
Very comfortable I'm 32" and these LG-size shorts fit perfectly! Soft tail bone protection helps me not to jump on my thin bike seat :-) Good all-around butt, hips protection. Very comfortable and low profile. Great work with riding jeans. Additional protection layer without making you bigger. April 14, 2014
runs way small, no elastication at seams Great concept, terrible execution, really wanted to love it. Based on the size chart I ordered LG, couldn't even pull these up past my thighs. I am 5'10" 185lbs normally wear size 33-34 straight cut jeans with 30" inseam. You should order 1-2 sizes up. The stitchings that attach the red elastic bands to the mesh chassis, those stitches have almost zero give. So A* basically defeated the elastics on these shorts by making stiff seams become choke points. What were they thinking... Otherwise the mesh is excellent, stretchy, etc. Those stitches ruin the shorts for me. For guys who want a fly and actually elastic waist loop, just take scissors and cut the entire front part out. The crotch mesh and the front black segment of the waist band. Then take it to a tailor and have a real elastic bridge sewn across the front waist. $5. Problem solved. February 16, 2014
A little extra protection, good price, but runs small! I bought these to wear under a pair of kevlar jeans along with add-in CE knee armor for a little extra protection. They're similar to slide shorts for paintball but have the added hip padding, which is nice. They're not too bulky, and fit well once they're on. Problem is, they run a little small in the waist and the waist band isn't very stretchy. Translation: if you've got a bit of a booty on you, they'll be hard to put on because you'll use up all of the elasticity. They also don't breathe super well, but that's almost to be expected. All in all I'm happy with the purchase, they're not a revelation or anything but I feel they're worth the price. And order one size up if you've got a round rear end! January 29, 2014
Pretty much you get what you pay for. Functional and low profile. Pretty much you get what you pay for. Functional and low profile. Might want some additional padding if you know you will be hitting hard :) January 5, 2014
Very snug fit, order up a size for sure!!!! If you are litterally looking for some CYA protection these are a good thing to get. Not noticeable under reasonably fitting jeans (I have the ICON Hoodlum jeans) and a decent, but not earth-shattering amount of protection. That said, ORDER A LARGER SIZE UP!!!! I'm 5'10'' and weigh 175lbs and have a 32 in waist and I had to get the large. No way was the medium even going to make it halfway past my thighs! #I have some other Alpinestarts stuff that is medium and fits perfectly, but these are a whole different story.# The large size is even a bit snug, but it's tolerable keeps the pads in place.

C W: Wanted just a little padding for trail riding and snowboarding. These shorts are perfect. Very comfortable too. Jun 11, 2014
Ramy H: These shorts work great! Wont protect from impact but for road rash it will help!! Apr 30, 2014
Gregory T: I chose to buy these undershorts because I thought they were a good alternative to buying motorcycle specific jeans or overpants. The price was right and the brand is proven. The padding isn't too thick that your regular jeans won't fit normally (no weird bulges with jeans on either) but seem to be thick enough to provide some level of protection. Feb 20, 2014
Jin P: solid coverage of thigh area, low profile, can be worn under normal clothes,, great price Feb 10, 2014

Brandan B: Based on reviews and knowing alpinestars to be a top brand in motox sport science I was a kid, and didnt want to go cheap on protection. Oct 1, 2013
Josh O: Needed something easy to slip on under jeans, and these work perfectly for what I need. Sep 14, 2013
victor r: Dirt rider review Sep 2, 2013
Jack J: Heard good things about these shorts, thought I would give them a try. Aug 22, 2013
Kyle S asked: Will this offer any in the way of slide protection? I'd like some protection for cruising around town (under 50mph, mostly) but that would be useless if the foam pads tear apart upon sliding. They look more comfortable than the Dianese hard pant. Which would be more suitable for my application? Sep 5, 2013

Chris G: These are lightly padded shorts best under an outer layer for abrasion resistance. They are made of a double layer of material with the pads sewn between them. When stretched you can see through the material a little. It is not opaque enough to wear as an outer layer. If you hit the road and slid in these without anything over them I think the material would shred pretty easily. As a light padding under riding pants though they are a nice pair of shorts.

Daniel N: These are really meant to be warn under something. The material is a thin mesh so I would not think it would hold up well in a slide. Not sure how it would do under jeans or something like that.

I wear them under my leather pants for bit of extra padding while riding. I don't think the pads would just tear out in a slide if they were under your jeans.

Antonino d: this shorts are made with two mesh layers and the foam pads are in between them. so, you must break your pants and the exterior mesh layer of the shorts for loosing the foam pads. Those shorts are very comfortable. I use a 34 size pants and an M size shorts and it fits me like a second skin. Sep 26, 2013
Reply to Antonino Good answer? Yes (0) No (0)
Samuel M: Honest answer to your question, at under 50 mph the pro shorts will work fine however if your an everyday rider keeping them clean is kinda a hassle. If you happen to lay it down pretty good the pads will tear apart but the shorts will keep you protected. I how this information was useful Sep 6, 2013
Reply to Samuel Good answer? Yes (0) No (0)
Haziz H: I wouldn't think it'll hold up in the way of slide protection. They're very soft and nothing sturdy at all. I got then more for padding since my seat is hard. My brother has a pair of the Dianese hard pants and that would be more suitable for your application, I believe. Hope this helps. Sep 6, 2013
Reply to Haziz Good answer? Yes (0) No (0)
Karan l: No slide protection from these shorts Kyle. Go with the hard pants or I'd invest in a good pair of Kevlar pants to go over these for complete protection. That how I roll and should be enough for your needs too. Sep 7, 2013

Eric C asked: Are these meant (or at least able) to be worn under track leathers for extra protection? Sep 11, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
Hassan M: I am not certain if they were meant to be expressly worn under leathers. They certainly fit on top of my under armor onesie and under my A* leather suit. If nothing else, they (should) offer a bit more impact protection, damping any immediate impact force, while the leather protects you during a slide. I also commute and go on spirited rides at times, using them for an added layer of impact protection, wishing I would never need to test them. :) Sep 11, 2015
Reply to Hassan Good answer? Yes (0) No (0)
Hugh P: These are more for mx use, however you can wear them on under your track leathers depending how tight they are. I wear them under my regular jeans occasionally and they are really snug. Also wear them when snowboarding as well. They're light but will fit snug if you already have fitted pants. Sep 11, 2015

Robert H asked: Are they CE approved? Dec 16, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Steve P: I have not seen anything that says they are CE rated. I really have never seen underwear/base layer rated for protection. It does have foam padding but no hard armor so I would say it offers some impact protection but minimal slide/rash protection. I use them under Kevlar jeans and they work well. Dec 17, 2014
Reply to Steve Good answer? Yes (0) No (0)
Chris G: These are not ce approved armour, they are about 3/8 - 1/2 inch comfort foam. It's like the foam back pad that comes in their jackets. That being said, they are nice shorts if a little additional padding is all you need. Dec 16, 2014
