Re: How protective is a textile jacket?
Texitle has come a long way especially if it is lined or interwoven with Kevlar. That being said leather is KING. I have crashed in both and would not hesitate to recommend leather over textile hands down. Road rash is a bitch!
Anyway this is an exert from an old tread that will give you some insight from controlled testing:
"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:
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
Boot leather (generally 2.2mm thick) 20
Leather stretch panels 20.4
There is also this test from a while back:
"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..."

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."
