Eureka Suma 3 Person Tent
Skip until the brand discloses water-repellent coating chemistry or commits to PFAS-free waterproofing.
This 3-person tent has polyester with water-repellent treatment standard for tents. The brand makes no statement on PFAS in water-repellent coating coatings or specific chemistry.

What Eureka Suma 3 Person Tent is made of, ingredients and materials
The Eureka Suma 3 is constructed from polyester fabric with a water-repellent coating (water-repellent coating) finish applied to the exterior. water-repellent coating coatings are the primary PFAS vector in modern camping tents; Eureka has not disclosed whether their water-repellent coating formulation contains long-chain PFAS, fluorocarbon alternatives, or PFAS-free chemistry. Polyester itself is not inherently hazardous, but the chemical treatment is the critical unknown.
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
Eureka has not disclosed whether the Suma 3's water-repellent coating finish contains legacy long-chain PFAS, short-chain fluorocarbon alternatives, or PFAS-free wax-based treatments. Without transparency, assume possible PFAS exposure during manufacturing, field use (breakdown into soil/water), and disposal.
Source, ATSDR ↗Polyester microfiber shedding
Polyester fabric can release microfibers during setup, takedown, and weathering. Risk is low in field use but increases if tent is repeatedly machine-washed. No specific data on this model, but inherent to polyester construction.
Coating degradation and leachate
As the water-repellent coating breaks down with UV and flex stress over years, small particles and residual coating chemicals may leach into soil/water at campsites. The nature of leachate depends on the undisclosed water-repellent coating chemistry.
What’s reassuring
Volatile organic compound (VOC) off-gassing
Polyester tents typically do not report formaldehyde or significant VOC off-gassing in field use. No specific recalls or complaints about the Suma 3 exist. Off-gassing risk is minimal compared to some adhesive-heavy outdoor gear.
Heavy metals
No documented cadmium or lead contamination in Eureka polyester tents. Polyester fabric dyes are generally lower-risk than those in wool or untreated cotton, and no independent testing has flagged this product.

The brand's record and disclosure
Eureka (a Johnson Outdoor division) has not publicly committed to PFAS-free waterproofing or disclosed the specific water-repellent coating chemistry used in any tent model. The brand remains silent on PFAS phase-out timelines despite industry movement toward fluorocarbon alternatives and wax-based coatings. No major certifications (Bluesign, GOTS, or similar) are marketed on this model, limiting independent verification of chemical inputs.
How it compares in its category
Most mainstream camping tent brands (Coleman, REI Co-op, Kelty) similarly lack water-repellent coating disclosure. Some smaller/premium brands (e.g., Hyperlite, NEMO) market PFAS-free options with fluorocarbon-free or wax-based water-repellent coating. The Suma 3 is competitively priced and widely available, but transparency is not a selling point. Budget-tier tents typically do not disclose water-repellent coating chemistry; this product is industry-typical in opacity.
If you buy it
Clean the tent with mild soap and water only; avoid harsh solvents that could degrade the water-repellent coating. Do not apply heat or dry-clean. Store dry and out of direct sunlight to slow UV degradation of the polyester. The water-repellent coating finish will degrade over 3-5 years of use; re-treatment products are available, but verify that replacements do not reintroduce PFAS before purchase. If PFAS exposure is a priority concern, request water-repellent coating ingredient disclosure from Eureka before buying.
