Question from guspvt
Hi Debra!
I go to the gym frequently and I’m not allowed to take a glass bottle with me. In this case, should I go with plastic or stainless steel (like Klean Kanteen)? I know they can leach chemicals and metal, respectively, into the water, but which one is better? If plastic is better than stainless steel, which type of gym bottle plastic would be the safest: one made with plastic number 2 (HDPE), number 4 (LDPE) or number 5 (PP)?
Thanks!! And keep up the excellent work! 
Best Regards,
Gustavo

Of the choices you’ve given me, I would choose the #2 HDPE, as it is food grade and high density.
