Grady P on Jun 20, 2016
from your video I got a pretty clear idea of the type of protection the pant provides, and of the air flow
bill b on Jun 10, 2016
Reasonably priced with reviews equivalent to more expensive shorts.
Mattia P on May 28, 2016
The only shorts I could find that have hard pads. Very pleased with the padding and it is pretty low profile so it fits beneath most pants. These run large so I would order a size smaller than you think you are.
John B on May 27, 2016
highly ranked

robert c on Dec 20, 2015
I'm hoping these padded shorts will fit under my regular jeans. The jeans I have are one size bigger to accommodate knee pads and padded shorts.
Myrdale L on Oct 18, 2015
Needed some additional protection under my adventure riding pants. These work well and are not too hot in the summer.

wanted hard plastic and tail bone protection to wear under motocross pants
gary j on Apr 11, 2015
I ordered another pair before this and the protection did not feel very solid. I plan to ride off road a lot and needed something with hard pads for better protection. These seemed to be the best fit for my need.
Kyle C on Apr 8, 2015
Because I feel naked without any protection around my waist

Rebecca T on Aug 25, 2017
Any word if they will be coming out with updated bionic shorts?
A shopper on Feb 19, 2017
Would these be suitable and good for street riding? Daily commuting, and joy riding? I can't always suit up in leathers. But would like to have some peace of mind knowing that if I slid across the pavement my hip and thoughts will still be useful. What other suggestions do you have? I like to be able to wear jeans when I'm in a rush and get called into to work for an emergency
A shopper on Mar 6, 2014
BEST ANSWER: Yes, they work well for that. They do not get too hot in the summer and provide better protection than most hip pads and riding pants. I purchased them and am using them because of the fact that I wanted more protection. As others have described they are well padded and you might have to get a pair of pants that will comfortably fit over them. Jeans with Kevlar panels will not help you in the initial impact, that's where these will come in and they could protect you from fracturing any bones in a crash. They run at least a size small though.
How does this armor compare to CE 1&2 level armors?
James D on Sep 29, 2014
BEST ANSWER: It's obviously very rugged, if not a bit overboarddue the enourmity and thickness of the pads. You really have to size the pants up to handle that thickness especially if you have large upper legs. On my superbike, I simply can't use them because my suit isn't sized accordingly. so I use my FOrcefields with a couple layers of padding removed. For offroad, I use my forcefields with all layers. I suppose the Alpinestars offer greater protection than my soft armour for punctures and point loads due to the hard plastic shell, but I tend to gravitate towards the more comfortable gear and hope for the best. For a racer, I'd choose Alipinestars for greater protection and size my suit/pants accordingly.
if my waist measurement is 32 what is the best size for me?
A shopper on Apr 23, 2011
BEST ANSWER: I'm 5'8", weigh 158. 32 pants are a bit large for me. I wear 31 waist when I can get pants in that size. I purchased MEDIUM and they fit fine. The waist/seat was maybe a tad large and the leg opening maybe a tad small, but I wore them for 2 full days at Cornerspin 'roadracing in the dirt' school and they were nearly perfect for me.
How well would this fit under a 1-piece racing suit? My suit came with some cheap foam hip protectors that have since torn off and I'm looking for something with a bit of hip/thigh/tailbone protection but don't want it to be too bulky or stick out of the suit too much.
A shopper on Dec 27, 2013
BEST ANSWER: I could not directly say. I ride off road so my pants fit a little loose but these shorts are pretty slim fitting. The hard panels are a little bulky but I do not see how you can get around that without going to just soft padded armor. If you want some hard stuff between you and the ground, I would imagine you have to accept a little bit of bulk. That being said, I doubt they would make it stick out a whole lot.
Hi, if i will wearing it with pants 'alpine stars A10 sport' it be comfortable or not?
Denis I on Jun 1, 2014
BEST ANSWER: I'm never aware that I'm wearing them while riding. They're that comfortable. I sit just a little forward of upright and ride an R1200GSA and a Yamaha WR250R.
Does these fit along the lines of compression shorts and boxer briefs?
A shopper on Jan 28, 2013
BEST ANSWER: More like boxers if you go up in size, but if you try true to fit, then like compression shorts.
I have a 38" waist and went for the XXL and they fit me perfect, even though they are slightly snug, but after one ride they have stretched a bit and I do not even feel them while I ride.
How good is the tailbone protection? I'm tired of tiny little tailbone pads that don't offer much protection. I fall on my backside a lot and I need better than average tailbone protection.
Gregory W on Feb 9, 2015
BEST ANSWER: It's pretty decent. It may not feel like much, but it has saved my behind multiple times (including landing in some rocks). If you're going to be coming down from more than 3 feet or so, I'd recommend looking for a little more protection. The price/performance is great, just make sure you get the sizing right.
Would you recommend using these shorts with, alpinestar Atem race suit? Is there added value?
Thamer I on Sep 20, 2014
BEST ANSWER: Recently crashed at a track day wearing these, about the only part of my body not bruised was my hip, so yeah, they work, and work well. you just need to check the fit of your leathers, mine are bit wide at the hip so had no problem wearing these, if you've tailored your leathers or have to really squeeze into them I can see it as being a problem.
How to wash and dry ?
A shopper on Jan 9, 2013
BEST ANSWER: They have wash instructions, but I am spraying them with a fabric freshener between washes, then hand washing and line drying them when they do need need a real wash. If you do machine wash them I would suggest putting them in a load with other large soft times like towels and pants. I would personally avoid machine wash as much as possible though, for both their sake and your machine's sake.
