Patching your pants' knees and butt

I consistently get holes on my butt from rock scrambling descents. 

Does anyone have a good method for repairing butt and knee holes on the pants?

I'm repairing it by hand with dental floss but it doesn't last. Was thinking about trying a patch with material like sunbrella.

Thanks

I don’t really have a good answer. Just a funny story.

Climbing at Joshua Tree National in the lost  horse area, we found a free soloist doing laps on the wall. He was wearing jeans that had at least 2 ft.² of duct tape on them covering various holes.I imagine he taped first from one side and then taped from the other so the duct tape layers would stick to each other through the areas of missing denim.

Face in when you down climb?

I have some sunbrella I can give you.

Pm your address.

I use duct tape

The easiest method is two iron on patches, one on the inside, one outside. It you have a sewing machine and can sew a zigzag stitch around the edge of the patch, it lasts longer. It’s typically fairly unsightly, but I personally embrace the crappy look.

I remember those.  And those patches are probably lighter than duct tape. 

I do also have to repair my pants often (mostly due to crampons).
I use a sticky path that I also glue with this magical glue "GUTERMANN HT2".
Apply some of the glue on the edges of the patch and it's pretty bombers even using a washing machine
