What material do you recommend for jackets? Keep in mind I'm in San Antonio. Its regularly 104 deg. right now and we have very mild winters.
If you go textile look at pretty much anything denier, typically, a higher denier rating is applied to area that are likely to spend anytime on the pavement, and primary initial hit areas.
Like 1000 in the elbow area, ( I believe this rating is actually how many pounds per square inch is required to tear the fabric), naturally, if its not stitched in well, its not worth the money.
Granted you live in texas, so unless you really, really, need goretex in the jacket, stay away from it as it doesn't breathe like normal fabric..
Stay away from nylon, (another melter).
Not knowing you style, but look over that site I mentioned before, then review the writeup. Maybe an adventure jacket with a zip in liner would suit you well. Look for ventilation, zips under the armpits and such.
Also think about the color, black is common, but hotter than hell on a sunny day, then there are the hi-viz colors, you will likely hear about in your class.
if you are on a fairly low budget, cortech/tourmaster makes some very good motorcycle clothing, however with the color schemes, ya either like it or ya don't.
Firstgear also makes a great jacket for 180.00
They can be had under 200 on sale and also check ebay from time to time once you find one you think you like.
I'm at the high end of gear now, a Darian Jacket, and heated liner for winter riding here in PA.
Just always be sure to review any protective wear prior to purchase.
Enjoy your new machine,
