Men's Jockey 2-Pack RapidCool Boxer Briefs
Likely lower concern, but no transparency on treatment chemistry.
These polyester-spandex boxer briefs use an undisclosed moisture-wicking treatment. Jockey provides no PFAS claims, third-party verification, or transparency on finish chemistry.

What Men's Jockey 2-Pack RapidCool Boxer Briefs is made of, ingredients and materials
These boxer briefs are a polyester-spandex blend, a common synthetic base that poses minimal chemical risk during normal wear. The RapidCool moisture-wicking treatment is proprietary and unspecified; such finishes are typically durable polymeric coatings applied to the fabric surface to enhance sweat evaporation. Because Jockey has not disclosed the chemical composition of RapidCool, it is impossible to rule out additives like PFAS or other synthetic polymers, though the treatment itself does not inherently require hazardous compounds.
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.
Antimony in polyester
Polyester production sometimes involves antimony trioxide as a catalyst. Most polyester apparel retains only trace residues that do not migrate during normal wear, but the risk exists if manufacturing controls are loose. Jockey's sourcing standards for polyester are not publicly disclosed.
Formaldehyde / VOCs
RapidCool is not stated to be formaldehyde-free. Some textile performance finishes use formaldehyde-based resins for durability. The undisclosed composition means this risk cannot be assessed; prolonged skin contact with residual formaldehyde is unlikely but not impossible in a newly purchased garment.

Polyester garments shed microfibers during washing. While not a direct health hazard to the wearer, the RapidCool coating may alter shedding behavior. Washing in a mesh bag and using shorter cycles can reduce fiber release.
Source, EPA ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Azo dyes
No reports of restricted azo dyes (those that cleave to carcinogenic amines) in Jockey boxer briefs. Polyester garments are typically dyed with acid or disperse dyes, most of which are not restricted. Without independent testing, however, this cannot be fully ruled out.
Flame retardants
Underwear is not required to meet flammability standards in most jurisdictions, so flame retardants are unlikely. No evidence of their use in Jockey boxer briefs is on record.

The brand's record and disclosure
Jockey, a major intimate apparel manufacturer, has no publicly documented recalls or significant safety controversies specific to their boxer briefs or moisture-wicking treatments. However, the brand maintains silence on textile chemical disclosure, including PFAS use in performance finishes. Unlike some competitors who pursue OEKO-TEX or similar certifications, Jockey does not advertise independent third-party chemical auditing for this product line, limiting buyer confidence in finish safety.
How it compares in its category
Standard polyester-spandex boxer briefs from most major brands (Calvin Klein, Hanes, Tommy John) carry similar chemical profiles and disclosure gaps. Jockey's RapidCool treatment is functionally similar to moisture-wicking finishes on countless athletic and everyday wear garments. If chemical transparency is a priority, certified alternatives (e.g., OEKO-TEX or GOTS-certified cotton blends) exist but are less common in men's brief categories and typically cost more.
If you buy it
Wash in warm (not hot) water to minimize any potential leaching of finish additives; cold water presents lower concern if you use it regularly. Avoid high-heat drying, which can degrade synthetic fibers and any surface treatments. Replace every 12-18 months with regular weekly wear to minimize long-term contact with aging synthetic coatings. Do not bleach or use harsh solvents, as these can break down the RapidCool layer and release trapped compounds.
