Reading this thread reminds me of a classic product from my early days here at the shop - the original Craghoppers made in West Yorkshire "Ra Breeches" made from a stretch fabric which was durable and fast drying. Generally available in dark navy with a contrast colour on the pocket insert. A great product from the past!

If you do go the route of lightweight waterproof consider the Montane Atomic which packs down small and provides total waterproofing combined with decent breathability. Expect to pay about £100. I have used my Atomic for "summer" UK hiking and cycling and it has never let me down.
