Good Morning ELCHINO,
The Pioneer pants have a zip out liner and zip right into your jacket. On the outside they have reflective materials on the side and up the leg as well as Nomex panels on the inside of the legs to displace heat and protect the pants from hot bike parts.. I will let someone else compare and contrast since I am a bit bias.. I will say that our products have Knox Armour in the Hips and Knees a well known leader in the protection business and are 100% waterproof. I will stop there..
