Great riding jeans for the $$!
I'm 5'7" and have tried on several riding jeans. They are mostly oversize, bulky, and ridiculously long. Most are designed to hem to length, but if you're shorter they look like clown pants.

So I took a chance and ordered these. Wow. They fit true to size, with enough elasticity that a slimmer guy could perhaps go down a waist size for style. After about 250 miles on them I can report that they are comfortable, and that the knee pads sit just about right - a big advantage of having pants sized by inseam, rather than just by waist size.

The downside - while they are Kevlar reinforced, the impact areas covered could be larger. And there is no hip protection.

Bottom line: For the price these jeans are outstanding in fit and feature. We'll see how they hold up after a few washings. But so far, so good.

Critical Mass Jeans
I'm 5-7 and normally wear a 36/30 pair of jeans. After watching the video and seeing the amount of stretch I ordered the 34/30. I actually could have gone down to 32/30 due to the stretch, and I'm sure it would have fit fine. The jeans are dark, almost black. I absolutely love the color and the style of the jeans. They look great and I have some extra room to move around. The knee armor sits perfect for me. This is my first pair of riding jeans and they do offer more protection than what I normally wear.

Perfect riding jeans!
These are my first pair of riding jeans, so i really can't compare it to any other brands, However, these fit and feel just like normal jeans. They look even better ( I got the dark blue ones...very cool). My wife and kids couldn't even tell they were riding jeans. I guess you can call these straight fit, but because of the elastic, stretch fabric, they feel like relaxed jeans. I'm 5'10", 200lbs, with an athletic built, especially with my thighs, so I usually buy relaxed fit in normal jeans. Knee pads fit perfectly. My only gripe was no hip armor, but not a deal breaker. I love these jeans, I can wear them to the office and around town and no one knows they're motorcycle jeans. Highly recommend them! Great job Speed and Strength!

My new favorite riding jeans!!
I wear a 34x30 and from reading other reviews I decided to get that exact same size. The Speed and Strength Critical Mass Jeans fit me perfectly with no issues whatsoever; there may even be a little extra room in the waste. Initially, riding with the leg armor installed was slightly uncomfortable but after a few miles I completely forgot about it. I would highly recommend these to anyone looking for a comfortable and mildly affordable pair of riding jeans.

Looks great, feels great, knee armor position is weird
First purchase from Revzilla, SUPER fast shipping holy cow!

Anyway, I love the look of these jeans. They basically look just like regular jeans, except with a knee pad in it. They fit true to size, I usually wear a 32x34 and these fit exactly like my 32x34 dickies. I'm 6'3" at 170lbs, so I'm on the tall and slim side of the scale, I wish S&S made these jeans in a 36 then they would be perfect.

My only gripe is that the knee armor pouch feels like it's really high up, so in a standard/sporty riding position, the knee armor really becomes thigh armor. Cruiser riding position or guys with shorter legs should not have an issue.

I'd say if these are your first pair of riding jeans, give them a shot. They feel sturdy and I would trust them in a mid-speed booty skid

Great jeans!
Wear a 33 normally but 34 in these fit perfect. Look and feel ass close to regular jeans while providing protection way above. The stretch makes these very comfortable. I have athletic legs (thighs and calves) and these fit the best of several jeans I tried on by a mile. Great bang for buck too.

Wanted to like them
After all, the price is great. But can't recommend them. Bought two pairs, tried them on, everything seemed to be in the right place. Washed them, so now I can't return them. Normally wear 36x32, bought 36x32. When standing, they fit perfect. There's enough extra at the bottom that I could cuff them a little and they wouldn't look bad. But when I sit on the motorcycle, the armor is so stiff that it hikes up over the knees. I can pull the armor lower, out of the pocket a little since it's velcroed in but it still doesn't sit right on the knees, there's no pre-curve or scoring. When I do kind of get it right (because there's so much stretch to the fabric) the armor on both knees twists inward significantly.

I can still wear without the armor because of the kevlar and get SOME protection, but I can't recommend these, which is a shame. When standing, they look great and it's a good price.

Not Dad Jeans
The only pair of motorcycle jeans I have found that don't look like hipster skinny jeans, or dad jeans. Perfect cut.

For comparison 5'10" 170 lb. 32/32 fits true. Knee pads are alright, but everything else, down to the stretch denim is great.

*I got my set on amazon.

Great Jeans, Great fit. Few Nitpicks.
I'm 6'1", 200 pounds, and I wear 34x34 in Levi's 501s. The fit of these jeans is the exact same as the 501s. I purchased 34x34 in the Critical Mass jeans. The waist seems a little big, but that could be due to the elastane baked in. The length is spot on. I got the dark blue color, and the overall finish is very nice. The jeans are not as thick as a pair of 501s, but they are thin enough to breathe well during the summer heat and have enough stretch to not bunch up anywhere. These jeans are extremely soft and comfortable; so much that I could definitely wear these all day at work. I don't feel that the denim material would hold up extremely well in a slide, but I didn't expect it to be the best. Hopefully the Kevlar would make up for that, but I don't plan on finding out.

The only nitpick I have is the knee armor. The armor tends to ride up onto my quad while riding. I do have to wear the jeans quite low on my waist for the armor to sit in the right location, but it's not low enough to be uncomfortable. This could be that I am riding with forward controls; riders with rearsets on their bikes may not have this problem.

Overall I'm very happy with my purchase. Thanks RevZilla!

Wanted to love but couldnt get size right
These seem like great jeans, the strech is awesome. I am 5'11" 215. Normally I wear a 38 in Levis but 36 in most stretch denim. I first got these in 38 they fit well but were baggy in the butt and thigh, so with them being stretch and listening to the video to size down, I sent them back for 36. With the 36 they were significantly smaller, waist had to use all the stretch and the butt, legs, knees where too tight to be comfortable or useful. So if you can get the right size they seem super comfortable, protection is not the highest it seems but i did not test that. Quality seems to be good.

Since there is so much stretch, if I am in between sizes should I get the smaller size? I noticed HVB wears 33 and he is in 34's in the video.....
A C on Feb 9, 2017
BEST ANSWER: on regular jeans a 34 is too tight, 36 too big ... 34 in these fit me perfectly. the stretchy waist helps with the smaller size.
Are they waterproof?
A shopper on Nov 6, 2017
BEST ANSWER: No. I plan to spray mine.
Do these have a place for hip pads or are they not comparable at all?
Jeff E on Oct 20, 2017
BEST ANSWER: they're stretchy so you could wear armored shorts under with no issue.
Are the critical mass jeans made out of Kevlar?
A shopper on May 28, 2017
BEST ANSWER: As mentioned before, Kevlar in the seat and knees only. Seems breathable. Good luck getting them to fit right.
Are these boot cut. Wondering if they’ll fit over my Sidi Cobra Air boots?
