Knee pads? What the???
I have a 5k pair of DC pants that I wear inbounds around here.
I always have an airblaster ninja suit on and if it's going to be in the 20's or lower, I wear a pair of workout track style running pants. Basically the same material as basketball shorts.
So a base layer in the ninja suit, a mid layer in the workout pants and then my outer layer of my pants.
And a mirrored setup for my upper body. My legs personally have less over heating issues then my upper body but as long as you have vents, you'll be good to dump off some heat.
With the weather we've been having, it's been in the 30's a lot so you may only need a base layer and an outter layer.
I'm slightly cold blooded and you probably are as well, coming from Florida.
