You know don't be afraid to spend some money on good (read that as durable) clothes. I have a pair of elasticized wool tights (Descente), that I purchased as a teen back in the 70s. And all I remember about them (at the time) was that they were freaking expensive as hell. I still have them and still ride with them probably 100+ days a year. I think I got my moneys worth out of them!
