Others have said it, but I'll chime in anyway:

-- biting insects, briars, etc. are no more of a problem kilted than if in shorts

-- if you're in serious tick country, long pants sprayed with repellant and tucked into your socks is the only answer. Looking good gives way to living without Lyme disease every time.

-- Heavy canvas will be much too hot in warm weather. I go for lighter cotton or PV if the mercury passes 70 F.

-- Body glide, because with the better air conditioning you will not build up perspiration and your bits may chafe

-- Can't beat wool if you might get wet / cold / both

-- Acrylic dries fast and is not a bad alternative for cool weather. Not recommended if it's hot or cold out

-- Be sure you either stick the sporran in your backpack or use a belt that lets you easily shift it around to the side. Your wee friend will thank you at the end of the trail.
