The why
LifeProof. Now an OtterBox sub-brand focused on waterproofing. Polycarbonate hard shell plus TPU bumper with waterproof seals around ports. Same dermal exposure framework as the parent OtterBox lines: documented BPA residual migration from polycarbonate consumer goods (NSF eyewear data ~0.53 micrograms per day, below California MADL but above zero) and potential brominated flame retardant skin transfer from TPU when present (Bessa 2023 ES&T, sweat increases bioavailability). Roughly 50% recycled plastic per OtterBox UL Environmental Claim Validation. No clean-product certifications. Score 4-5. Ingredients verified 05 2026.
