Been some questions about what kind of gear to buy. Found this awhile back and thought might be good to post up again.


Tear and Abrasion Strength by the numbers
Pounds of force until fabric tears Abrasion cycles on pavement until fabric fails
CottonJeans 4.5 pounds to tear 50 cycles to failure
70 Denier Standard Nylon 4.5 pounds to tear 165 cycles to failure
500 Denier Polyester 8 pounds to tear 180 cycles to failure
200 Denier Standard Nylon 7.5 pounds to tear 275 cycles to failure
500 Denier Cordura 22 pounds to tear 710 cycles to failure
620 Denier Cordura 35 pounds to tear 1200 cycles to failure
NEW Competition Grade Leather 80-110 pounds to tear 1200-1700 cycles to failure
1000 Denier Cordura 110 pounds to tear 1780 cycles to failure
Air Mesh Kevlar 1260 pounds to tear 970 cycles to failure Stretch Kevlar Blend 420lbs pounds to tear 1800 cycles to failure

This is how quickly some materials take to hole:
Material Seconds
Denim 0.2 to 0.5
Some race gloves 0.6
Most leather gloves 1.0 to 1.8
Keprotec stretch material 0.9
Poor Kevlar 1.0
Two layers of waxed cotton 1.3
1.3mm thick cow hide 3.8
Two layers of 1.3mm thick cowhide 18
Three layers of 1.3mm thick cowhide 55
Two layers of Kevlar plain weave 5.6
Suede 18
Boot leather (generally 2.2mm thick) 20
Leather stretch panels 20.4


There is also this test from a while back:

Drag Test

"For the Drag Test, samples were stitched to a bag that held a 75-pound
sandbag inside a milk crate, then dragged behind a pickup truck..."

New, 100% Cotton Denim Jeans ----------------------- 3' 10"
Senior Balistic Nylon ----------------------------------- 3' 10"
Leather, Lightweight, Nude Finish, 2.25 oz/sq. ft. --- 4' 3"
Leather, Fashion Weight, 1.75 oz/sq ft. ------------- 4' 4"
Two-year-old 100% Cotton Denim Jeans ------------ 4' 5"
Cordura Nylon Type 440 ----------------------------- 18' 3"
Kevlar 29 Aramid Fiber, Style 713 ------------------ 22' 1"
Leather, Competition Weight, 3 oz/sq. ft. -------- 86' 0"


Taber Test

"For the Taber Test, the specimen was mounted on a rotating platform and
scuffed by two rubber-emery grinding wheels." The numbers represent the
number of revolutions until the fabric totally fails. A vacuum clears
debris.

Two-year-old 100% Cotton Denim Jeans 168
New 100% Cotton Denim Jeans 225
Kevlar 29 Aramid Fiber, Style 713 506
Cordura Nylon, Type 440 559
Leather, Lightweight, Nude Finish, 2.25 oz./sq. ft. 564
Leather, Fashion Weight, 1.75 oz./sq. ft. 750
Senior Ballistic Nylon 817
Leather, Competition Weight, 3 oz./sq. ft. 2600

More to consider...

"Finally, protection from road abrasion cannot be guaranteed by a
materials abrasion resistance alone. A jacket may have panels of
highly abrasion-resistant materials, yet if low-quality stitching joins
those panels and the seams come apart upon impact or during a slide, then
the abrasion resistance of the panels could count for nothing.
Furthermore, an ill-fitting garment may ride up in a slide, contorting
the body and exposing the skin. And the best jacket in the world, left
unzipped and/or unsnapped, won't give riders the protection they pay
for. When it comes to safety, the issues are more complex than just the
abrasion resistance of materials." __________________

From another site:

The textiles vs leathers debate is all about tradeoffs. Choosing which material to use to cover your hide with and spend your pennies on depends on how much you value individual tradeoffs and ultimately, your intended use and riding conditions. Sounds easy enough, but deciding between textiles vs leathers has had great rider minds in a muddle and increasingly so over the last couple of years as the quality and versatility of both materials has improved so much! Just type in “textiles vs leathers ” into google and you will find that 90% of the results are from forums with the answer ultimately resulting in the fact that it depends on your personal preferences. The problem is that this does not help those new to the biking world who have not had the time or experience to develop their own, well-guided preferences… and so the argument goes on.
But, it’s really quite simple if you use the BMI (Best Motorcycle Information) textiles vs leathers test. This test takes the four most differentiating attributes of the two materials into consideration – price, maintenance, comfort and protection. Each attribute is also assigned to either leathers or textiles, depending on which material has the greater advantage in terms of the attribute. After reading the brief summary on each, assign a score out of a hundred to each attribute, giving those attributes that are most important to you higher scores, so that in the end the total score of your four attributes adds to 100. Then add up the score that you gave to the leather attributes and textile attributes, and the material with the highest score is your answer – and best of all it will be unique to your personal preferences.
Price - Textiles
Motorcycle textiles are cheaper to buy than leathers. It is also much harder to judge the quality of leathers and so you take the risk of paying a lot of money for a suit that does not have quality stitching and construction. (Just beware however that it is widely accepted that your textile suit will probably only survive one crash before you have to fork out for a new pair.)
Maintenance - Textiles
This one is simple – motorcycle textiles can be thrown in a commercial washer, while leathers will need to be sent to the cleaners.
Comfort - Textiles
Motorcycle textiles have an all weather capability: vents for when it is warm, liners for when it is cold and water resistance for rain. It breathes more easily than leather, and water slides off it like a ducks back.
Leather is also much heavier than textile.
Protection - Leather
Tests are conducted all the time to compare the abrasion resistance of motorcycle riding gear materials and leather always comes out on top as the most durable material. Furthermore, leather does not melt from friction, it will cushion your fall more than motorcycle textiles would and it offers the best protection against a road rash. The fact that leather also lasts through multiple crashes whilst textiles will probably only last through one, says a lot about the difference in protection and impact between the two materials.
The textiles vs leathers debate basically comes down to protection vs everything else.

on the road tests, from personal experiance -
jeans & t-shirt - road rash to the bone & broken limbs, severe bruising.

jeans & denim jacket - same as above

jeans & waxed cotton bike jacket - same as above but elbows escaped.

textile bike jacket with elbow & shoulder pads + leather bike pants - bad bruising and road rash to arms & sides, bottom half bruised.

heavyweight armoured leather bike jacket & pants - no bones broken ( apart from hand lol) road rash to knee at side of slider, bruising all over but no road rash to upper half.

i know what i'd rather be wearing
not too sure about the figures for kevlar - on the road it really doesn't offer much protection and gets shredded almost instantly, rendering it useless, whereas leather (usually) buffs up ok after a minor off.

not doubting the figures, just saying that roads have different surfaces, some fine, some very coarse ie tarmac vs concrete would be very different wear characteristics for each fabric.

main point of interest, as i've said before, denim is only good for soaking up blood.
NEVER RIDE WITHOUT GLOVES!!!

It would appear that riding in jeans is about as effective as shorts. The issue for me is I know what the best protection would be, but I have not found any that is comfortable enough to wear all the time. It is a balance between the two (comfort and protection) that I try to strike. I always wear gear helmet to boots, but when it gets warm it is just difficult to dress in armored pants and leathers and not sweat into a big puddle. I do have a couple pairs of kevlar lined jeans and a mesh jacket for those warmer days. If it so uncomfortable that you leave it at home, the best gear will do you no good.

Thanks for posting that chart, Sherry, I had never seen it before. Some day, when I get rich, I will have a good set of Leathers for Winter riding. Winter is when the roads around here are most treachorous and the people on them are at their nuttiest!
Thanks again......there's good info there.
It must be good.......it pretty much goes along with what I've believed for years :biggrin:
 
#12 ·
you guys need to remember that leather slides a LOT better than textile regardless of what durability characteristics it may have. when textile catches pavement and tears, it doesn't do you any good.

kangaroo and stingray leathers slide better than cowhide, full grain better than top grain cowhide, and so forth. abrasion resistance doesn't tell the whole story.

then again i'm a guy that rides in a 2 piece leather suit, race boots and gloves....so what do i know? :D

How are you able to do that in the summers? Do you just deal with the sweat? Do the vented arms provide enough venting to make it tolerable? It has to be at least as hot in Georgia as it is here in northern Alabama.

I do plan on buying some leather stuff when it cools off a bit. Buying all your gear is expensive. So, I can't do it all at once. I still need some pants. My temporary solution is a pair of 15oz (very thick denim) Carhartt pants that are on the way, combined with some motocross knee pads that fit under my pants. I've been eyeing some "slider" undershorts, but those have to wait until next month too.
 
#15 ·
my leather jacket is vented, but my other leather jacket isn't and i got by with it all last summer. yes, you simply deal with the sweat. yes, gear is expensive. yes, it's worth it.

yes, your friends and everybody you meet up with will think you're crazy or weird at first. i kinda like that feeling i get from people, the wtf how can you do what you do kinda shock value of it all.

the irony of it is, over time, you seem to hear it less and less. i've only had like 3 people this year ask me if i was hot. last year it was like 30+.

lol @ assless chaps. i never understood the point in that. like it's hard to pull a pair of pants down when you have to do your business. well it can be easier said than done with track pants but eh, it's certainly do-able. not to mention there's no protection for your manhood. how do you explain to a woman that you lost your dick in a motorcycle accident because you thought i was more important to cover your legs than your balls?

I'd love the protection of leather but won't spend the bucks on it because in this heat I know I wouldn't wear it. I think a bigger problem with the heat is not the sweat but the possibility of dehydration and heat stroke. I can sweat, that's fine. It's simply not safe or smart to defeat the body's natural way of cooling itself by suiting up in full leather. Indeed, it does get to hot to ride.
IMHO, while it does afford the best protection I think for me leather is to much. I mean really. I believe if I'm ever in a motorcycle accident (again) it will be more impact and less slide. Mesh or textile with good armor seems to be more important to me than the ability to slide along the pavement at 100mph. I don't push mine or the bikes limits, I cruise and if theres a wreck it's going to be someone turning left in front of me or rearending me or something like that, most likely in town at speeds under 40mph or so. My biggest problem will be broken bones and blunt force trauma, not lack of skin. I try to pick gear that fits my riding style and if I were young and riding rockets to the edge, I'd match that up with quality leather. But I'm older, wiser, and much more careful. I won't say I won't get a bit of rash should the worst happen. But if the worst does happen I'll have much bigger problems that a little rash.

it's not hard to bring along a couple gatorades or stop and buy one now and then.

you're simply justifying a lack of protection. sliding at 50 mph isn't much better than sliding at 100. it doesn't matter how hard you think you ride, ok? i know what you mean, but it simply doesn't justify your reasoning. old age and wisdom doesn't help you in an accident.

Theres someone driving past you in their car saying ''all that gear wont help that kid on the motorcycle if hes in a crash''.. Theres an SUV driving by that car saying ''that little thing will get crushed by my car''

Your on a **** bike!!!

If you atgatt nazi's are so worried about crashing, please get off your bikes and into a cage.

Dont get me wrong, gear is important. But having 2 grand in the latest most technologically advanced gear isn't going to do sh1t against the real threat.
 
#19 ·
With all of the debating aside, I still think it is good data (the abrasion data) for people to use in making up their own minds, to help them decide what gear to buy. For us new riders (like me) I could wreck in any way you could probably imagine. My closest call so far has been instinctively jerking my head to avoid a small bird, while in a curve!

I'd at least want to know "how much better material X "could" protect my skin in a slide. Personally, I love the mesh, armored summer jacket I bought, but I will buy some leather for late fall, winter, and early spring. Hopefully I can come up with the cash by then.
 
#22 · (Edited)
you guys keep justifying riding without gear. call me a gear nazi, whatever. that's cool. but telling me it won't do me any good if i hit a car or solid object is complete BS. it will do it's job of keeping you in one piece, preventing worse bone breaking/ligament/tendon tearing, dislocation of limbs and digits. it can allow you to keep the blood in your body that you can lose during severe road rash. hard back and chest protectors can prevent spinal damage and chest bone breakage, which can pierce the lungs/heart/etc. it would suck to die with all your skin but a rib poking through your lungs caused them to fill with blood and you simply suffocate to death. wearing full gear can be the make or break point, it's not simply about abrasion resistance.

of course there are certain situations where it won't matter, but the same goes for you thinking old age and wisdom keeps you protected. admit it, it simply doesn't. at least wearing all the gear is taking a proactive stand, a personal insurance policy instead of just going with the 'whatever happens, happens' ideology.

two grand on latest technology? get real, i have less than $500 invested in all my gear. i don't exactly have a new Dainese airbag suit, ya know?

telling me to get in a cage if i'm scared of crashing....you really aren't acting your age, if you're as old and wise as you claim. i'm certainly not scared to go down, because i know what it feels like to go down when you're protected. if you want to run a belt sander all over you body willingly, that's fine. i don't care to know what that feels like.
 
#24 ·
that's how i feel about it, in real life i never have anybody give me any **** about wearing full gear. it's only online. go figure?

in the same light, i never chew out the guys on my group rides for not wearing gear. ironically enough, they all start wearing more and more gear as they ride with me more often. coincidence? who knows.
 
#26 ·
This I like. I've heard many folks say " I should probably wear a helmet but I don't." They already know they should wear gear and have a certain amount of guilt about chosing not to I suppose. Then they start hanging with a guy who's got the balls to wear it full time and all of a sudden they feel like less of a person. "Heck, if he's tough enough to wear it I'm certainly as tough as he is" and they start wearing it too. Good way to get people into better habits.
 
#25 ·
First, I never claimed to not wear gear. In fact I wear full gear, gloves to boots. I simply don't wear leather gear.
Second, assuming you were refering to me with the "acting your age" comment, I never told you to drive a cage.
Your choice of gear is fine by me, more power to ya. My choice is my own and you don't have to like it or agree with me. And getting all bent because I'm not inclined to agree with you is a better indication of your maturity level than my choice of gear is my own.
Besides, I'm not really disagreeing with you, just agreeing that gear is important on a different level.

I had a thread earlier this year when a Harley guy asked me how I ''ride with all that **** on''.. I told him ''my sweat dries faster then my skin and bones heal''

I didn't give him an attitude that I'm a better/smarter/safer rider then him. nor did I tell him hes stupid for not wearing full gear.

Sometimes I don't wear any gear. If its hot as balls out and I'm driving through the city at 30mph, I'll go in shorts and a T.

That's my right to do that, and if it means I get some road rash if I fall.. Owell, that's the risk I take, just like the risk I take every time I get on my bike.
that does not give anyone the right to say they are smarter or safer then me.

After 300,000+ miles I would say I have the wisdom and experience to wear whatever I want on my bike without some internet warrior telling me I should do otherwise.
