i have a medium sized timbuk2 from about 7 years ago that has a sweet black liner that is thick as hell and never gave me a problem, Then i bought an super big one on discount about 4 years ago and have used it everyday, and finally the liner is wearing through at the corners. Both decent quality, with cordura and heavy vinyl liners, but with all regards, the new ones look like crap and I would now go with a reload or bailey for both aestetics and qaulity of construction. Also note. the 7 year old one has "lifetime warrantee" and the company phone# stitched into the timbuk2 label on the front pocket and the 4 year old one doesn't.
