hey Bruce,
No worries ... glad you've had good experience with your jeans. Using rain pants over is smart ... I do the same over my dirt riding pants or leathers.
What brand Kevlar Jeans are you using?

If you look into so called "Kevlar Re-inforced" jeans you'll find that first off, they use a small amount of Kevlar strands, and only in the "Impact" areas. (hips, butt, knees)

This helps protect the fabric from burning through when sliding down pavement at 50 mph. But most serious injury happens on IMPACT.
But it would be nice to have that Kevlar protection if sliding down a gravel road. But I'd imagine the jeans would still get torn up?

For me good quality armor and pads are more important than Kevlar fabric. Ballistic Cordura fabric is pretty rugged ... but I rely more on armor I use underneath than the fabric itself. If armor is placed accurately it can prevent broken bones.

The other thing about Kevlar Jeans is that a very small percentage of actual Kevlar is typically used in the impact areas ... like 5% or 10%? So it's a bit of Kevlar thread woven into the Cotton fabric. Several moto magazines have looked closely at several brands of the Kevlar reinforced jeans.
Not all good reviews.

"Draggin Jeans" are one of the most popular brands. But several other companies now make these jeans ... even Cycle Gear.

In high heat and humidity with temps over 35C I find jeans are HOT and sweaty. They also get wet both from your own sweat and from a tropical shower. They do not dry out quickly. Crotch Rot and Monkey Butt seem to be a common complaint of jean wearers I've ridden with. Heavy jean denim fabric is relatively heavy compared to dirt riding pants.

Riding off road sometimes can be hard work, so we sweat a lot. Vented, mesh type gear tends to allow the sweat to evaporate fairly quickly. Jeans stay wet for hours. Monkey Butt?

But can't argue with your experience ... and it sounds positive! When I lived in El Salvador and Guatemala (2 years) I gave up all my jeans, for casual wear (not riding), wore what locals wear: Wash & Wear wrinkle free syn blend pants. Thin, light, no wrinkles, easy wash (unlike Jeans) and dry super quick ... and less sweat!
