Hey all, about to buy my first pair of leather pants, and with summer coming I'm wondering if the Alpinestars Track pants are worth the extra hundred bucks over the Apex pants, the only real difference appears to be that they have perforation on some of the panels. I don't mind spending the extra money if they will actually help me stay cooler, but if it's a waste, I don't see the point in bothering. Also, any idea how much these things will stretch, especially in the thigh area? I tried on a pair of the Apex pants at PS yesterday and they were… not easy to put on. GEtting 'em clasped and zipped took a solid minute or so, but the gentlemen said they'd stretch and I'm better off getting 'em in that size since they'd stretch, and that way I've got the knee armor in close to the right place (it was a bit low on me in the next size up, I've got short legs for someone my height & size).
