Check out Motoport or Aerostich pants, depending on what you are looking for. Both are US brands that have the option of being repaired as needed. Motoport is 100% custom made to your measurements and Aerostich has custom options like shorter or longer inseam, etc. Both are pricey, but so is Klim.
Motoport is awesome if you are looking for warm to hot weather gear, particularly in dry weather. It also works in the cold and wet if you're willing to layer. But the armor coverage is huge and it is very abrasion resistant. The Kevlar mesh is great for warm to hot weather. The Kevlar stretch works great in cool to warm weather. The stretch also is good for long rides in really hot weather so you don't get dehydrated.
Aerostich uses Goretex, which is great for wet, cool weather. But is hot in warm weather. I only use my Aerostich Darien about a month a year. But I'm in Phoenix, so warm weather gear makes more sense for me. Hence the Motoport gear.
