I use G-Form knee pad and elbow pads. Very comfy and zero issues with them being too hot in summer with temps +100 degrees in the southwest. I even wear them ebike work commuting just in-case I have an accident from a distracted driver. Don't want to experience road rash at +20 mph.
The G-Form also come in longer knee and shin guards, ankle guards, and compression tops and bottoms with padding.
