Under Armour Triumph Campus Pro Backpack
Backpack likely treated with water-repellent coating; Under Armour provides no PFAS transparency.
Under Armour backpacks typically feature water-repellent coatings on synthetic fabrics, common vector for PFAS exposure. Brand offers no public disclosure on PFAS content or alternatives used.

The full breakdown
What it's made of and why it matters
The Triumph Campus Pro uses polyester and nylon as primary materials, both petroleum-derived synthetics that are chemically stable when unworn but require finishing treatments for water resistance. The water-repellent coating (water-repellent coating) finish is the key concern: manufacturers typically apply fluorinated or fluorine-free repellents to fabric surfaces, and this product provides no material specification. Polyester and nylon themselves do not leach problematic monomers under normal use, but the applied coatings are where chemical risk concentrates in backpacks.
The brand's record and disclosure
Under Armour has not published detailed chemical disclosure statements or transparency reports about water-repellent coating treatments, flame retardants, or heavy metal dyes in its apparel lines, unlike brands such as Patagonia or Fjallraven. The company does not appear on ZDHC (Zero Discharge of Hazardous Chemicals) gateway or bluesign approved supplier lists. No product-specific safety recalls or regulatory actions are on record for this backpack model, but the silence on chemical inputs reflects an industry-wide disclosure gap at Under Armour.
How it compares in its category
Most mainstream backpacks in this durability tier (Jansport, North Face, Osprey) also use polyester with undisclosed water-repellent coating finishes, so this backpack is not an outlier in chemical transparency. Premium outdoor brands (Arcteryx, Rab) disclose more fully and often use fluorine-free water-repellent coating, which reduces PFAS exposure. Budget alternatives may use lower-quality nylon that degrades faster and sheds microplastics; this product's heavier gauge likely performs better on durability but offers no chemical advantage.
If you buy it
Wash the backpack by hand in cool water before first use to reduce loose dyes and finishes; avoid machine drying or heat exposure, which can degrade nylon and accelerate any coating breakdown. The water-repellent coating finish will weaken over 1-2 years with regular washing; reapplication with fluorine-free water-repellent coating products is an option if you retain the backpack long-term. Store in a cool, dry place away from direct sunlight to prevent photodegradation. If you notice coating peeling, adhesive failure, or odor, discontinue use to avoid microplastic or chemical exposure.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
water-repellent coating composition (fluorinated vs. fluorine-free unknown)
Under Armour does not disclose whether this backpack uses legacy fluorinated water-repellent coating (which contains PFAS) or newer fluorine-free alternatives. The finish is present for water repellency but its chemical identity is undisclosed, making assessment of non-PFAS fluorine hazards impossible.
Azo dyes in polyester/nylon
Polyester and nylon backpacks are commonly dyed with azo dyes, some of which can release carcinogenic amines under degradation or prolonged heat. Under Armour does not certify restriction of banned azo dyes; risk is typical for the category but unconfirmed for this model.
Heavy metals in synthetic pigments
Colored polyester and nylon may contain cadmium, lead, or chromium in pigments, particularly in dark or vivid colors. No testing data available for this product; risk is present in the material class but not uniquely elevated for Under Armour.
Microplastic shedding from degraded coating or fiber wear
As the water-repellent coating finish ages or the polyester/nylon breaks down mechanically (especially if washed frequently or roughly), the backpack will shed microplastics. This is a long-term environmental hazard rather than acute toxicity, but relevant for products worn or stored near food or water sources.
Formaldehyde or formaldehyde-releasing preservatives in textile finishes
No recalls or safety alerts exist for formaldehyde in Under Armour apparel. Modern synthetic backpacks rarely use formaldehyde finishes, though low-level residues from dye baths are not ruled out; risk appears below established concern threshold for this product type.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
