Where these two actually differ
- We flag Polyurethane coating degradation and off-gassing, Microplastic shedding from coating and Skin irritation or allergic response to coating chemicals on the Helix and not on the Parachute.
- We flag Azo dyes or heavy metal pigments, VOC off-gassing or odor and Mildew or mold growth if damp on the Parachute and not on the Helix.
- The Helix is polyurethane or polyester blend with waterproof coating (unspecified) where the Parachute is 100% linen, no reported 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 Parachute is the one to buy.
- We are less certain about the Helix grade, at 45% confidence against 82%, 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 →
