Just a FYI

Secret #3: Thin Kevlar® thread reduces seam strength.
Unlike textiles, more threads per inch in leather makes it weaker, not stronger. Kevlar® is a very strong aramid fiber made by DuPont® but it makes a lousy thread for motorcycle gloves because it doesn’t stretch when the gloves undergo stress. That makes it act like a cheese knife cutting through the leather and letting the gloves rip open. Lee Parks Design gloves use a special “dual-duty” design that has two strong nylon threads per hole, engineered with just enough elasticity to maximize the seam strength.

I tried them on at the IMS NY Show and they felt great. Wouldn't hesitate to buy a set, very comfortable.

I tried them on at the IMS NY show also, they had a really good feel and dexterity to them. I ended up going with Held "Steve" gloves which I like a little bit more ( even better feel), but for the money the Lee Parks are a bargain. (and the gauntlet coverage is a little more than the "Steves")

I've had a pr. for 3 years, maybe 4..

Nice fit, excellent quality. The leather is a bit soft; good for comfort, but gets chewed up by the knurled metal grips on my bike. Will proly have to spring for a new pr. this year. Overall, A+, IMO

You really need to consider how coarse the fabric is that you are stitching into.

Kevlar "thread" is in denier which equates to how many grams per 9,000 meters. Heavier/higher denier means a heavier thread.

You really ought to use similar denier to that which the jacket is made out of. Lighter denier can tear/cut the parent fabric, heavier can tend to displace the fabric where it punches through.

Some protective leather garments have seams both glued and stitched; so does not depend only on threads/stitching.

Lee Parks gloves are awesome! I order them a little snug and they 'wore in'. I decided to try a pair as I go through Joe Rocket gloves every few months.

i'm getting 2 jackets. one leather and text. the leather quality over here is actually as good as i've seen it in the states, and textile is also of good quality.

i've also seen spun nomex thread, any thoughts on that?
