Where these two actually differ

  • Neither product has a hazard flagged against it, which is uncommon and is why both grade as well as they do.
  • The Darn Tough is Merino wool blend, nylon, spandex where the Smartwool is Merino wool blend (primary natural fiber), 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.

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 →
