We both on our second set now and only wear our Kevlar jeans for a day ride only, so if we are away overnight or longer distance we wear our textiles.....
Our current pants are the DriRider GS speed although not our first choice they do meet our needs and the requirements we set down (Armour, vents, Waterproof

) and were VERY well priced

and couldn't be turned down.
So the trip just completed had temps from 28 to 5 degrees with sunshine to constant hours of light rain and a few heavy down pours at times. We remove the bulky winter liner from the pants and leave at home, instead taking compact Icebreaker thermal merino underwear if needed and pvc rain pants, these are waterproof BUT don't breath.
So temps down to 18 in fine or light scattered showers with vents open/closed as required had us comfy and dry. Below 18 or predicted to be well below had us add the far more compact merino thermals.....travelled Vic Highcountry in sub 10 degrees in comfort.
While the DriRider style pants are marketed as waterproof they are really only rain resistant......fine for a few light showers throughout the day, but it will come through eventually, particularly in the groin area.
While adding the plastic type pants over the top will keep the rain out, You will get wet anyway from sweating your

off......
Our general rule of thumb....average temps and light showers = Pants only
Cold temps = Pants and thermals
Warm and wet = Pants and suck it up buttercup for the little water that gets in
Cold and Wet = Pants, Thermals and PVC pants bearing in mind that with the
Merino thermals they will wick most of the moisture created by
PVC rain pants.
To buy pants that are Warm, Cool, Waterproof and Breath in an armoured motorcycle garment is not an easy task.....Gortex is close but hot and big dollars
