TETON Sports Mountain Ultra Tent
Unknown waterproof treatment. Tent makers often use PFAS. Request specs first.
Mountain Warehouse won't disclose the waterproofing chemistry on this tent. Most outdoor tents use water-repellent coating coatings containing PFAS, though some newer brands are shifting to alternatives.

What TETON Sports Mountain Ultra Tent is made of, ingredients and materials
The TETON Sports Mountain Ultra uses polyester fabric as its primary material, which is inherently non-toxic and widely used in outdoor gear. The critical unknown is the waterproof coating applied to the polyester; manufacturers typically use either PFAS-based treatments (like Teflon-type coating/Teflon variants) or fluorocarbon-free alternatives, but Mountain Warehouse has not publicly disclosed which type is on this tent. Polyester itself does not leach chemicals during normal camping use, but degraded or poorly applied coatings can shed microparticles.
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.
Waterproof coating composition (unspecified)
Mountain Warehouse does not publicly disclose whether the waterproof treatment contains PFAS, fluorocarbon-free alternatives, or other chemicals. This is the primary unknown hazard for this specific product.
Microplastic shedding from coating degradation
If the applied waterproof coating is low-quality or degrades over time (especially in UV exposure or with poor care), tent fabric can shed microparticles. No field data on this brand's coating durability exists in public records.
Off-gassing of VOCs from new material
New polyester tents often emit mild odors from adhesives and finishes. This is typically brief and non-hazardous in outdoor ventilated environments but may be noticeable when first pitched in enclosed spaces.
What’s reassuring
Azo dyes in polyester fabric
Polyester tents may use azo dyes in coloring; TETON Sports does not disclose dye chemistry. Risk is low in outdoor use since contact is minimal and dyes are fixed during manufacturing, but no testing of this specific product is on record.
Adhesive or glue in seam sealing
Seam tape adhesives used on budget tents are rarely disclosed; most are non-toxic when cured, but composition is unknown for this product specifically.
How is this PFAS grade calculated?
The brand's record and disclosure
Mountain Warehouse has not published material safety data sheets, PFAS treatment specifications, or third-party certifications for their camping gear. This silence is typical of budget outdoor brands but limits your ability to verify what waterproofing chemistry is used. The brand does not appear in public PFAS reduction commitments or textile sustainability rankings. Without direct contact, the waterproof treatment composition remains genuinely unknown.
How it compares in its category
Budget polyester tents like this occupy the mid-range safety profile, cheaper than premium brands (which often disclose coatings) but less opaque than ultra-budget alternatives. Established outdoor manufacturers like MSR, REI Co-op, and some Decathlon lines now specify treatments without intentionally added PFAS or use wax/silicone alternatives. TETON Sports falls into the 'silent' category alongside most mass-market camping tents, making direct comparison difficult without requesting technical specs.
If you buy it
Store and use the tent as-is without heating or flame exposure, which could degrade the coating and release particles. Avoid machine washing; hand rinse only with cool water and mild soap to preserve the waterproof layer. Inspect seams and the fabric surface annually for peeling, cracking, or flaking; if coating visibly degrades, replacement presents lower concern than repair. Request the manufacturer's Material Safety Data Sheet or product specification sheet directly via their website or customer service to clarify the waterproof treatment used.
