Under Armour Men's Essential Tech Boxerjock 3-Pack
Lower concern. No coatings disclosed, inherently PFAS-risky finishes unlikely.
These nylon-spandex boxer briefs contain no disclosed coatings and use materials unlikely to require PFAS treatments. Under Armour makes no waterproofing or stain resistance claims or PFAS disclosures.

What Under Armour Men's Essential Tech is made of, ingredients and materials
This product is a nylon and spandex (elastane) blend without disclosed chemical coatings or finishes. Nylon is a synthetic polyamide polymer that does not inherently leach into skin or sweat under normal wear conditions. Spandex provides stretch and recovery but is chemically stable in finished form. The absence of stated water-repellent coating (water-repellent coating) or antimicrobial coatings reduces exposure to chemistry-heavy finishes common in performance apparel.
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.
Microfiber shedding and degradation
Synthetic nylon and spandex release microfibers during washing and wear, a documented environmental concern. This is not a direct health hazard to the wearer but a product-use consequence; standard for all synthetic athletic underwear.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Azo dyes and colorants
Nylon and spandex textiles can be dyed with azo compounds; no recalls or warnings on record for Under Armour boxerjocks. Standard industry practice includes compliance with EU and REACH restrictions on banned azo dyes, though under-disclosure of dye chemistry is common in US mass-market apparel.
Formaldehyde / VOCs
No wrinkle-resist, water-repellent, or antimicrobial coatings disclosed for this product, making formaldehyde release unlikely. Basic nylon-spandex blends without specialty finishes typically carry minimal formaldehyde risk.
Source, ATSDR ↗Heavy metals
No published testing or recalls for lead, cadmium, or chromium in Under Armour apparel dyes. Nylon and spandex can absorb dye metals during manufacture, but established textile standards restrict these in finished products sold in North America.
Source, FDA ↗Antimony in polyester components
This product is nylon and spandex, not polyester, so antimony catalysts are not relevant. No antimony exposure hazard applies.
The full breakdown
The brand's record and disclosure
Under Armour has not published detailed chemical disclosure statements for basic apparel lines comparable to outdoor or technical brands. The company has faced no major recalls or public hazard reports specific to boxerjock products. Under Armour maintains OEKO-TEX or similar third-party certifications on some product lines but does not clearly advertise them for this basic three-pack. Transparency on restricted substance management is not a noted strength relative to competitors.
How it compares in its category
Basic nylon-spandex athletic underwear is a standard, low-risk category. This product sits in the mainstream safety tier, no antimicrobial silver, no flame retardants (not required for underwear), and no disclosed water-resistant chemistry. Competitors offering similar nylon blends without added finishes present comparable hazard profiles. Premium athletic brands sometimes disclose full restricted substance compliance; Under Armour's silence is typical for mass-market basics but not reassuring.
If you buy it
Wash in warm water before first wear to remove any residual dyes or finishing agents. Avoid hot dryer heat, which can degrade spandex elasticity over 50+ cycles. Replace when elastic fails or synthetic fibers pill excessively (typically 12-18 months of regular use). Normal skin contact and sweat exposure do not pose a leaching risk with nylon-spandex blends absent special coatings.
