Daisy Chain Web Duffel Bag vs Discovery Dry Bag: which is safer?
Kelty Daisy Chain Web Duffel Bag is the clear pick. SealLine Discovery Dry Bag carries a failing PFAS grade, and we never recommend buying a failing product.

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 Coating leaching and chemical migration, Degradation of waterproof integrity over time, Microplastic generation from fabric abrasion and Undisclosed waterproofing chemistry (possible PFAS or alternatives) on the SealLine and not on the Kelty.
- The Kelty is Polyester webbing and nylon where the SealLine is Urethane-coated nylon fabric with waterproof treatment, 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 45% 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 →
