Norrona Trousers
Ideal for those with long legs and slim waists the Norrona trouser collection is vast. These are cycling specific ones and cannot really be used for anything other than cycling with all their zips / leg tapering / and larger knees to accommodate knee pads.
I own 4 pairs in various colours that are on year 5 of use in some cases. It's a big initial investment but long term they'll stand the test of time for those conscious about sustainability.
The Flex 1 range is for all year round use, the infinium ones feature windstopper fabric so ideal for autumn, and the Dri1 are waterproof for winter.
