it's pretty evil, manufacture is evil & tremendous, it releases PCBs into the atmosphere from the time it is manufactures until it disappears in a 1000 years, smells like bad while doing that. Polyvinyl chloride

I think everyone uses it because everyone uses it and it's cheap. Looking at all the messenger bag options the only ones that don't use it are Under the weahter and baileyworks, under the weather not at all, baileyworks still has some pvc offerings.

I asked, because yes I am one of those people that won't buy something I don't agree is at least okay, and the owner replied that the only reason they didn't switch away from PVC earlier is that they had lots of trouble finding the new material in a form that could withstand colder than -20 c and they sell mostly to canadian messengers and cyclists. The TPU they have is rated to below - 40 c, is the only one that is, and at x6 the cost of PVC is one of the most expensive TPU out there, but it doesn't crack. at all.

so i was impressed. it's a small company, but the owner wrote back because she appreciated my stand that plastics should be used responsibly.

UTW and Baileyworks, and Timbuk2, but T2 uses a tpu laminate that has its own issues. that and I want made in north america thank you very much

IRO is steel, from tiawan okay, I'll bend a little see? not a complete nut, but yeah i threw out my bisphenol stuff and wont buy more.
