Where these two actually differ
- We flag Azo dyes in polyester webbing, Adhesive and seam-tape volatiles (VOC), Formaldehyde resins in fabric finishing and Microplastic shedding from webbing degradation on the Kelty and not on the SealLine.
- We flag PFAS in DWR coating, Coating degradation and particle shedding and Microplastic shedding from nylon on the SealLine and not on the Kelty.
- The Kelty is Polyester webbing and nylon where the SealLine is Nylon fabric with DWR waterproof 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 Kelty is the one to buy.
- We are less certain about the SealLine grade, at 35% 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 →
