Where these two actually differ
- We flag Fluorocarbon surfactants in Gore-Tex membrane, Durable water repellent (DWR) finishes on nylon upper and Off-gassing of volatile organic compounds (VOCs) from adhesives on the Garmont and not on the Timberland.
- We flag PTFE and fluorocarbon microparticle shedding, Formaldehyde resins in leather tanning and finishing, Azo dye residues in nubuck finish and Adhesive and glue volatiles at seams on the Timberland and not on the Garmont.
- The Garmont is Gore-Tex membrane with nylon upper where the Timberland is Leather, nubuck, rubber sole with waterproof treatment, 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 →
