I can’t give you European recommendations, but as someone who has had pant challenges, I can make those. Consider evaluating why they are failing. Are the rips and tears in the fabric panels? You may be able to find pants that are reinforced in those areas or are of a more durable fabric. You could also consider repair. If the rips and tears are at seams, maybe you need extra stitching. This can also be repaired but isn’t always cost effective. Also consider fit - if they don’t for appropriately, this also can lead to increased wear.

Good luck! Sorry if I come off as a lecture and you know all these things.
