I never hike in long pants, but in preparation for my TGO Scotland hike I purchased these (apparently lots of ticks there) .
They are deigned for trail running. They fit true to size (M) and are so light at 90grm on my scales (Patagonia say 87). Fabric is more robust than my Montbell wind pants that I occasionally use around camp in shoulder seasons.
Web research is full of praise for these pants. Looking forward to trying them in two weeks on the Able Tasman (if weather is cool)
