GQ did a good roundup on this very topic: https://www.gq.com/story/best-pants-to-bike-to-work

My favorites are a pair of Outlier OG's - they don't make that particular design anymore, since it was their very first model (I've had them for 11 years, so they were definitely worth spending $150 on back then). I don't have to dress up often these days, so my daily pants are Swrve's cordura jeans.
