Eureka Tent Timberline Green 2-person Tl-2 Camping Outdoor
Skip unless the brand discloses water-repellent coating chemistry, tent waterproofing has traditionally used PFAS.
This 2-person tent uses polyester ripstop with water-repellent finish typical of camping tents. The brand doesn't disclose water-repellent coating chemistry; historically tent makers relied on PFAS treatments.

What Eureka Tent Timberline Green 2-person is made of, ingredients and materials
The Timberline 2 uses polyester ripstop fabric, a lightweight synthetic weave chosen for tear resistance and packability. The critical component is the water-repellent coating (water-repellent coating) coating applied to achieve waterproofing without a full-layer membrane. water-repellent coating formulations are where PFAS contamination risk concentrates in tents, historically, fluorochemical compounds were industry standard because they provide water and stain repellency at low cost. Eureka! has not publicly disclosed whether this model uses PFAS-free or traditional fluorinated chemistry.
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
Polyester tent fabrics almost universally used fluorochemical water-repellent coating in this price range until recent years. Eureka! does not disclose whether the Timberline 2 uses legacy PFAS or newer alternatives; skin contact and inhalation during setup pose theoretical low-level exposure, with higher risk during fabric off-gassing in warm storage.
Source, ATSDR ↗What’s reassuring
Microplastics
Polyester ripstop does not release microplastics under normal camping conditions (no abrasion, heat, or water stress sufficient to fragment the material). Long-term UV exposure will cause fiber brittleness and pilling, but not ingestion-level particle release.
Source, EPA ↗Dyes and colorants in green polyester
Polyester apparel and outdoor gear are subject to EU/OEKO-TEX standards in many markets; azo dyes and heavy metal pigments are well-controlled in legitimate manufacturers. No documented issues with Eureka! tent colorants.
Flame retardants
Camping tents are not classified as upholstered furniture and do not require flame-retardant treatment. Polyester ripstop is naturally flame-resistant enough for its end use; no added halogenated or phosphorus flame retardants expected.
Source, EPA ↗Rubber or adhesive off-gassing from seams and poles
Seam tape adhesives and tent-pole sleeves may release small amounts of volatile organics (VOCs) during first use or storage in warm conditions, but odor dissipates within days of airing. No toxicological concern documented for this product category.
The full breakdown
The brand's record and disclosure
Eureka! (Johnson Outdoor) has not taken a public stance on PFAS elimination across its tent line or issued transparency reports on water-repellent coating chemistry. The brand does not appear on lists of outdoor-gear makers (like Patagonia or Arc'teryx) that have committed to PFAS phase-out. No recalls or safety advisories specific to this model are on public record. Without direct inquiry to Eureka!, the water-repellent coating chemistry remains unknown to consumers.
How it compares in its category
Entry-level tents in the two-person, budget-conscious segment (Eureka!'s market position) rarely disclose water-repellent coating type; competitors like Coleman and Ozark Trail offer similar opacity. Tents marketed as PFAS-free (e.g., some Hilleberg models) are typically higher-priced and explicitly advertised. The Timberline 2 is competitively positioned on price and durability reputation but lacks the transparency advantage of certified eco-brands. If PFAS exposure during setup and long-term storage in garages is a concern, this model offers no reassurance.
If you buy it
Store the tent in cool, dry conditions away from direct sunlight to slow water-repellent coating degradation; UV and heat do not off-gas water-repellent coating coatings significantly, but they reduce water-shedding effectiveness over 3-5 years. Avoid machine washing the tent; hand-rinse with cool water and mild soap only. Do not apply aftermarket waterproofing sprays without checking compatibility. Contact Eureka! customer service to request water-repellent coating material safety data before purchase if PFAS avoidance is a priority.
