shakedbc2I sent Gregory an Email asking, and saying specifically that I was buying through Massdrop and they responded.

StephireI can tell you they are fantastic about warranty. You won't have any issues with it. Gregory is top notch - I can speak from experience. I have a 7 year old Baltoro that I sort of "hate" because it just won't die :). j/k - I love it.
