After about 20 years of use, my fabulous Endura MT500 MTB shorts are finally close to being ready for the bin. I've looked for a straight replacement but it seems these are no longer made and have been replaced by a newer product but the Endura website neglects to say what this product is called. Does anyone know where I could get a new pair of MT500s (old stock) or what the equivalent is in the current Endura line-up? I don't want bibshorts or shorts so thin you could spit through them. My old MT500s are quite a thick material and are super comfy and hard-wearing.
