Where these two actually differ
- We flag Fluorinated water-repellent treatment (DWR) chemistry and Coating wear and microfiber shedding on the Tamrac and not on the Think Tank Photo.
- We flag Undisclosed water-repellent coating chemistry and Coating degradation over time on the Think Tank Photo and not on the Tamrac.
- The Tamrac is Nylon/polyester fabric with water-resistant coating, unspecified DWR treatment where the Think Tank Photo is Ballistic nylon, weather-sealed fabric, metal hardware, 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 Think Tank Photo is the one to buy.
Both products run through the same public rubric: 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 →
