Ferrino Sling 2 Tent
Skip until Ferrino reveals coating chemistry or certifies PFAS-free.
This backpacking tent has polyester with waterproof coating that Ferrino won't specify. Without lab testing, certifications, or PFAS statements, you can't verify actual risk levels.

What Ferrino Sling 2 Tent is made of, ingredients and materials
The Ferrino Sling 2 uses polyester fabric, a synthetic polymer chosen for weight and cost efficiency in camping tents. The critical unknown is the waterproof coating applied to the polyester; most budget to mid-range camping tents use either polyurethane or silicone-based coatings, with some brands relying on fluorochemical (PFAS) treatments for durability and water repellency. Without Ferrino's disclosure, the coating chemistry and longevity cannot be verified, and polyester itself can off-gas volatile organic compounds (VOCs) when new or stored in warm conditions.
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.
Volatile organic compounds (VOCs) from polyester and coating off-gassing
New polyester tents commonly emit VOCs in the first 24-72 hours, particularly formaldehyde and other solvents used in fabric finishing. Without coating-specific disclosure, additional VOC emissions from the waterproof layer cannot be ruled out.
Coating degradation and leachables over product life
Polyester coatings degrade from UV exposure, heat, and mechanical stress. As the coating breaks down, residual solvents, plasticizers, or unreacted fluorochemicals may leach into contact with skin or water, especially if used in warm climates or high-UV environments.
Microplastic shedding from degraded polyester and coating
Aged polyester tents can shed microfibers and coating fragments, particularly where fabric flexes or where the coating cracks. These particles may contaminate camping areas and groundwater if the tent is not properly disposed of at end of life.
Formaldehyde / VOCs
Polyester fabrics are often finished with formaldehyde-based resins for water resistance and wrinkle resistance. Ferrino does not publicly disclose whether the Sling 2 includes such finishes, and off-gassing is most intense in warm, enclosed conditions common during camping.
Source, ATSDR ↗Skin irritation or sensitization from coating contact
Unknown coating chemistry means potential presence of irritants, preservatives, or unreacted monomers. Individuals with sensitive skin may experience localized irritation from prolonged contact with the untested interior or exterior surfaces, especially when damp.
The full breakdown
The brand's record and disclosure
Ferrino is an Italian outdoor brand with decades of history but no publicly available PFAS certifications, disclosures, or third-party testing results for the Sling 2 or similar tent models. The company does not appear to have committed to fluorochemical-free coatings or transparent supply chain reporting as of available records. This silence is notable in a category where transparency has become increasingly common among premium competitors.
How it compares in its category
The Sling 2 sits in the lightweight, budget-friendly segment. Competitors in this tier (Coleman, Decathlon budget lines) rarely disclose coating chemistry either, making the entire segment a PFAS grey zone. Higher-end brands (Big Agnes, Nemo) increasingly offer PFAS-free or clearly labeled water-repellent coating treatments, while ultralight brands often use silicone-only coatings. The Sling 2 offers no competitive advantage in transparency or material safety.
If you buy it
Ensure adequate ventilation during initial setup and first nights to allow VOC off-gassing. Avoid prolonged skin contact with the tent fabric, especially when wet or warm. Do not store the tent in direct sunlight or heat above 65°C (150°F), as this accelerates coating degradation and potential leaching. Replace the tent if seams separate, coating flakes visibly, or waterproofing noticeably fails, as degraded coatings may release trapped chemicals or microparticles.
