Trespass Trossach Tent
Skip until Trespass discloses water-repellent coating chemistry or certifications.
This tent uses polyester with waterproofing but Trespass won't disclose the water-repellent coating treatment chemical. Without lab testing or brand transparency, PFAS risk cannot be ruled out.

What Trespass Trossach Tent is made of, ingredients and materials
The Trossach uses a polyester fabric shell with a waterproof coating of unspecified chemistry. Polyester itself is stable and does not leach endocrine disruptors under normal camping conditions. The critical unknown is the water-repellent coating (water-repellent coating) treatment applied to achieve water resistance, which in many budget-to-mid-range tents relies on fluorinated compounds (PFAS-family chemicals) that persist in the environment and bioaccumulate. Without Trespass disclosing whether they use PFAS-free or PFAS-based water-repellent coating, the coating's safety profile cannot be assessed.
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
The waterproof coating is necessary for function but Trespass does not disclose whether it uses PFAS, silicone, or wax-based water-repellent coating. Industry norms suggest PFAS is common at this price tier. Graded separately under PFAS verdict; hazard level here reflects material uncertainty only.
Source, ATSDR ↗Coating degradation and recoating uncertainty
As water-repellent coating coatings age (typically 3-5 years of field use), water repellency declines and users often recoat with commercial water-repellent coating sprays. If Trespass-supplied products degrade faster than competitors, owners may apply aftermarket treatments of unknown or problematic chemistry without guidance.
What’s reassuring
Microplastics
Polyester tents do not typically shed fibers in normal use. Risk is minimal unless the fabric is mechanically abraded severely or degraded by UV over many years of field storage. No recalls or field reports for the Trossach model.
Source, EPA ↗Off-gassing from polyester or adhesives
New polyester tents may emit slight solvent odor (vinyl acetate or similar from adhesives used in seam construction) for the first few days. This is temporary and not documented as a hazard for the Trossach specifically. Ventilation during initial setup minimizes any perception.
Heavy metals
Polyester tent fabrics in this category are not known to contain lead, cadmium, or other regulated heavy metals in their dyes. No recalls or test results on record for Trespass tents. Standard industry oversight makes this a minor concern.

The brand's record and disclosure
Trespass is a UK-based outdoor retailer focused on value pricing. The brand has not publicly disclosed its water-repellent coating chemistry or pursued PFAS-free certifications for tent products. No major recalls or contamination incidents are on record for this model. Trespass's silence on fluorochemicals is consistent with many mid-market brands that have not yet adopted transparency or reformulation, leaving consumers without critical sourcing information.
How it compares in its category
Budget camping tents rarely disclose water-repellent coating treatment. Mid-range competitors (Coleman, Outwell) similarly lack public water-repellent coating documentation, making the Trossach typical rather than an outlier. Premium brands (Hilleberg, MSR) increasingly offer PFAS-free or disclosed alternatives, but at 2-3x the price point. The Trossach sits in the transparency gap that defines most affordable tents sold in Europe and online.
If you buy it
Use the tent as designed in outdoor settings where water runoff flows into soil or waterways (understand you may be contributing fluorochemical dispersal if water-repellent coating is PFAS-based). Avoid heating the tent interior excessively or storing it damp for weeks, as heat and microbial activity can degrade coatings unpredictably. Inspect seams and coating annually for flaking; once the coating delaminates, water repellency fails and reapplication with unknown chemistry may be necessary. Do not machine wash; rinse gently with cool water and air dry.
