Why this grade

Where these two actually differ

  • We flag DWR coating composition (fluorine-based or fluorine-free unknown), Mold and bacterial growth from moisture retention and Coating adhesion loss over time on the Think Tank Photo and not on the B+W.
  • The B+W is Optical glass lens with multi-coated optical surfaces where the Think Tank Photo is Nylon ripstop fabric with DWR water-repellent coating, which is most of the difference in these two grades.
  • The gap is 45 points, wide enough that this is not a close call, and the B+W is the one to buy.
  • We are less certain about the Think Tank Photo grade, at 45% confidence against 82%, because it discloses less.

Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
