Calvin Klein Plus Womens Moisture Wicking Workout Pullover Top
Moisture-wicking apparel often uses water-repellent coating treatment, Calvin Klein provides no PFAS disclosure.
Moisture-wicking workout tops typically receive water-repellent coating finishes, which may contain PFAS. No public transparency from Calvin Klein exists on treatment chemistry or testing.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Water-repellent coating finishes on activewear commonly use fluorochemicals; Calvin Klein does not disclose whether this top uses PFAS-based or alternative chemistry. Skin contact during perspiration is the primary exposure route. Graded separately at 20/100.
Source, ATSDR ↗Azo dyes in polyester
Polyester fabrics often use azo dyes for color, which can release aromatic amines under skin moisture and friction. No specific testing on this product exists in public record; concern is standard for synthetic athletic wear without certified dye restrictions.
Microplastic shedding
Polyester synthetic fibers naturally shed microplastics during washing and wear, especially in performance fabrics with complex weaves. The moisture-wicking coating may accelerate degradation. Washing in a microfiber-catching bag reduces environmental release but does not eliminate risk.
What’s reassuring
Antimony in polyester
Polyester production may involve antimony catalysts; residual levels in finished fabric are typically very low and not reported as a safety issue for apparel. No documented cases of dermal antimony transfer from polyester clothing.
Formaldehyde / VOCs
Moisture-wicking treatments do not inherently use formaldehyde releasers. Wrinkle-resistant or anti-shrink finishes (common on cotton) would pose this risk, but polyester does not require them. No evidence of formaldehyde treatment on this specific product.

What it's made of and why it matters
This pullover is a polyester blend engineered with moisture-wicking treatment, likely a hydrophilic or water-repellent coating (water-repellent coating) finish applied to the fabric surface. Polyester itself is chemically stable, but the treatment layer is where hazard concentration occurs. Moisture-wicking treatments often use fluorochemical finishes to repel sweat and water while allowing vapor transport, though some brands now use non-fluorinated alternatives. The blend construction means dyes and finishing chemicals penetrate multiple fiber types, increasing surface area for potential skin contact.
The brand's record and disclosure
Calvin Klein (owned by PVH Corp) has not publicly committed to fluorine-free moisture-wicking treatments or disclosed the specific chemistry of this top's finish. The brand has faced no documented recalls or safety actions specific to this product line. PVH Corp signed the ZDHC Gateway commitment to chemical transparency, but product-level disclosure on performance apparel remains minimal. Calvin Klein does not advertise PFAS-free status or provide material safety datasheets to consumers.
How it compares in its category
Performance activewear moisture-wicking treatments commonly use PFAS-based chemistry; this product is typical for mainstream athletic brands. Higher-priced alternatives from Patagonia and Decathlon increasingly market PFAS-free options, while budget fast-fashion activewear rarely disclose treatment at all. Calvin Klein's positioning is mid-market standard, functional performance without transparency. Wool or cotton-blend workout tops eliminate moisture-wicking chemical risk but sacrifice the breathability performance this design targets.
If you buy it
Wash inside-out in cool water before first wear to reduce residual finish transfer to skin. Use cold water for all subsequent laundering; heat (dryers, hot water) can degrade coatings and potentially mobilize chemicals. Air dry to preserve the moisture-wicking treatment and avoid unnecessary heat exposure. Replace the top if visible coating breakdown occurs (peeling, stiffness loss, or balling) as compromised finishes may release particles during wear.
