I wear Mountain Hardware Canyon pants. Between the bugs and my propensity to sun burn, I need long pants. If it is really cold out, I switch to an old pair of Sportive built polyester pants sold by LL Bean many years ago. These are the same pants I ski in because the cut the wind while still breathing decently in cold weather, don't absorb moisture and stretch.
