Alo Body Wave One-Piece Bodysuit vs Women's Bottom Turn Racerback Bikini Top: which is safer?
Patagonia Women's Bottom Turn Racerback Bikini Top is the clear pick. Alo Yoga Alo Body Wave One-Piece Bodysuit carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag Azo dyes and color fastness, Spandex finish residues and volatiles, Microplastic shedding on degradation and Contact dermatitis from dyes or finishes on the Alo Yoga and not on the Patagonia.
- We flag Elastane (spandex) degradation under heat or chlorine on the Patagonia and not on the Alo Yoga.
- The Alo Yoga is Nylon blend (primary fiber); elastic/spandex blend construction where the Patagonia is Nylon/polyester blend with elastane (standard swimwear), which is most of the difference in these two grades.
- The gap is 25 points, wide enough that this is not a close call, and the Patagonia is the one to buy.
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 →
