Where these two actually differ
- We flag Corrosion of stainless steel hardware and Coating degradation and exposure of substrate on the Nomad and not on the Spigen.
- We flag TPE material degradation, Microplastic shedding and PFAS in waterproofing coatings on the Spigen and not on the Nomad.
- The Nomad is Anodized aluminum, stainless steel hardware where the Spigen is TPE (thermoplastic elastomer) with waterproof sealing, 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.
- We are less certain about the Spigen grade, at 42% confidence against 72%, because it discloses less.
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 →
