Super Hipster
Brand PFAS statement on record, which we have not verified.
Aisle says its leakproof layers have no PFAS and that SGS testing found no detectable PFAS. We record that as an unverified brand claim. Mamavation reported no fluorine detected in Aisle (formerly Lunapads) period underwear.

What Super Hipster is made of, ingredients and materials
Super Hipster uses organic cotton and wood pulp fiber as absorbent core materials. Organic cotton excludes synthetic pesticide residues present in conventional cotton, reducing dermal contact with persistent chemicals. Wood pulp fiber (often viscose or lyocell-derived) is a cellulose material with minimal inherent toxicity, though processing method (closed-loop vs. traditional) affects environmental impact rather than product safety. The absence of synthetic polymer coatings or water-repellent treatments in the described composition eliminates common sources of chemical leaching in period products.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Azo dyes and synthetic dyes
Organic cotton still undergoes dyeing; if conventional (non-reactive) dyes are used, some azo dyes may persist. Brand marketing suggests eco-focus but specific dye certification (e.g., OEKO-TEX) is not confirmed; contact brand for dye standard used.
Allergic contact dermatitis from dyes or finishes
Organic cotton reduces pesticide residue but does not eliminate risk from dyes or residual processing chemicals. Users with sensitive skin or dye sensitivities should pre-wash and patch-test; contact brand for full ingredient disclosure if reactions occur.
What’s reassuring
Brand-stated PFAS-free
The brand states this product is PFAS-free. We have not verified the claim.
No PFAS found in lab test
No PFAS detected in independent testing.
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
Organic cotton and wood pulp typically do not require formaldehyde-based durable-press finishes. No formaldehyde resin treatment is documented for this product; risk is minimal for this material class.
Source, ATSDR ↗Antimony in polyester
No polyester confirmed in the core material composition. If elastane (elastic fiber) is present, it is a polyurethane, not polyester, and does not carry antimony risk.
Microplastics
Organic cotton and wood pulp are cellulose-based and do not shed microplastics. Absence of plastic-backed layers eliminates a primary microplastic source in period underwear.

The brand's record and disclosure
Aisle has made a public PFAS-free claim, which we have not independently verified but is on record. The brand markets toward eco-conscious consumers and emphasizes material transparency, though detailed third-party certifications (GOTS, OEKO-TEX) for this specific product line are not confirmed here. No established recalls, safety violations, or disclosure controversies for Aisle period products are documented in public safety databases. Brand positioning suggests attention to chemical inputs, though independent lab verification of claims would strengthen confidence.
How it compares in its category
Period underwear commonly uses synthetic fiber blends (polyester, nylon, elastane) for moisture-wicking and fit retention, often combined with plastic-backed absorbent layers that introduce microplastic and chemical leaching risks. Super Hipster's organic cotton and wood pulp approach avoids polyester and plastic backing, positioning it as lower-risk than most mass-market alternatives. However, it trades some durability and performance for chemical safety; elastane content (if present for stretch) is not detailed and warrants clarification with the brand if elastane sensitivities exist.
If you buy it
Wash before first use to remove any residual dyes or finishes. Machine wash warm (not hot) with mild detergent, avoiding fabric softeners and bleach, which can degrade elastane and compromise absorbency. Air dry or low heat to preserve fiber integrity and elasticity. Replace when elastic loses tension or absorbency drops noticeably, typically after 50-100 wears depending on flow and care. Store in a dry location to prevent mildew in the absorbent core between uses.
