Where these two actually differ
- We flag Chemical overdose or misuse, Degradation and loss of efficacy over time, Glass bottle breakage and spillage and Chlorine residue and taste/odor on the Aquamira and not on the Hydro Flask.
- We flag Silicone degradation over time and Microbial growth in cap and straw on the Hydro Flask and not on the Aquamira.
- The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the Hydro Flask is Stainless steel bottle, silicone straw cap, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
