I wore a NOP shirt for my long run this weekend. It was comfortable and pretty cool for a Halloween run. It's been about a year since I bought the shirt and it was not on sale. I remember thinking I had gotten ripped off b/c when I bought it they charged my CC immediately but I never got a confirmation email and it didn't come for like 3 weeks. I reached out to their customer support and they never got back to me. I did eventually get the shirt, though. And I love it.
I don't own any tracksmith stuff, but I might get those long running pants. The HEPS themed stuff just seems cheesy. You either ran in the IVY League or you didn't. If you did, you'd never wear that imitation stuff. If you didn't, you have no business pretending to be an IVY League runner. Right? The normal non-HEPS stuff seems pretty nice though.
