I seriously don't think it's worth getting proper cycling trousers - just a pair of tracksuit bottoms with shorts underneath see me just fine.
I think someone else said something similar, along the lines of wearing "technical" trousers with shorts underneath.
My experience (such as it is) suggests that the cycling specific stuff can be better if you need to to use the pockets to carry stuff. Certainly my
Altura shorts hold stuff in the pockets in near perfect comfortable position while riding, and are far better than the non specific baggy shorts I was wearing. If the Altura trousers are as good as the shorts, they'd be worth considering (although the sizes are on the large side, imo).
