Plus Majestic gets to sell them more.

All valid points.

This is probably why we don't see cool base pants as they would rip the first time a player slides into a base.

For me personally if I sink in 100-150 dollars for a jersey I need them to last (due to finanical reasons) so I'll put up with the heat of a non cool base jersey for a few hours. I went to a camp last summer and I think I was the only guy wearing a coolbase jersey. But they certainly are more comfortable to wear than the old school jerseys.
