I’ve just bought two pairs of trouser after 25 years of only wearing baggies or 3/4s for trails and commuting.
A pair of Madison Zenith 4 seasons (£80) – which feel a bit like work trousers by Dewalt or something – but are tough, adjustable, comfy and i won’t mind getting absolutely filthy; and a pair of smarter Pearl Izzumi Versas (reduced to £60) from Biketart. The Versa are much slimmer and are idea for a less muddy commutes and for not looking too spoddy if I wear them at work at day.
Both are nicely wind proof, have plenty of vents and seems water repellent, rather than waterproof, but are good tools for the respective jobs.
I’m 5’11” and 33/34 waist, so a looser large for the Zeniths and snugger 34″ for the Versas.
