Where these two actually differ

  • 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 Mainstays.
  • We flag PFAS in waterproof coating, Phthalates and plasticizers from polyester/polyurethane blend, Volatile organic compound (VOC) off-gassing and Coating degradation and microfiber shedding on the Mainstays and not on the Parachute.
  • The Parachute is 100% linen, no reported coating where the Mainstays is Polyurethane or polyester blend with waterproof coating (type unspecified), 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 Mainstays grade, at 35% 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 →
