Six Moon Designs Lunar Duo Outfitter Tent
Higher PFAS risk due to water-repellent coating with no transparency.
This tent uses ripstop nylon with water-repellent treatment, but the brand hides coating details. Traditional water repellents historically contained fluorochemicals.

What Six Moon Designs Lunar Duo Outfitter Tent is made of, ingredients and materials
The Lunar Duo uses ripstop nylon as the primary fabric, a tightly woven polyamide known for tear resistance and light weight. The critical component is the water-repellent coating (water-repellent coating) finish applied to the exterior; Six Moon Designs has not publicly specified whether this is fluorine-based (PFAS-containing) or fluorine-free. Ripstop nylon itself does not off-gas formaldehyde or release volatile organic compounds under normal camping temperatures, making the coating the primary chemical concern.
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
Undisclosed waterproof finish on nylon ripstop is typical of fluorocarbon-based water-repellent coating treatments, which contain PFAS compounds that persist in the environment and accumulate in human blood. Brand silence on fluorine-free alternatives suggests conventional Teflon-family coating.
Source, ATSDR ↗Nylon microfiber shedding
Ripstop nylon can shed microfibers when abraded, especially during packing, unpacking, or weathering. This is not specific to Six Moon Designs but inherent to nylon textiles; outdoor washing accelerates fiber release.
water-repellent coating degradation and leaching
As the fluorocarbon water-repellent coating breaks down over years of UV exposure and wear, residual PFAS compounds may leach into groundwater when the tent is washed or during rain contact with soil. This hazard emerges over the product lifetime, not at purchase.
What’s reassuring
Formaldehyde / VOCs
Ripstop nylon typically does not contain formaldehyde-releasing resins; these are more common in cotton and cellulose textiles. No recalls or published testing for formaldehyde in this product line exist.
Source, ATSDR ↗Heavy metals
Nylon ripstop is typically dyed with synthetic azo dyes; modern suppliers test for banned cadmium and lead under REACH regulations. No reported contamination in Six Moon Designs tents; risk is low for this material class.

The brand's record and disclosure
Six Moon Designs (trading as Outfitter) maintains minimal public disclosure regarding chemical inputs or manufacturing certifications. No independent testing results, OEKO-TEX certification, or PFAS transparency statements appear in brand materials or third-party reviews. The brand does not distinguish between PFAS and fluorine-free waterproofing options, which is standard practice among more transparent manufacturers. This silence, combined with use of a water-repellent coating, suggests conventional fluorocarbon treatment is likely but cannot be confirmed from available information.
How it compares in its category
Most budget and mid-range camping tents use fluorine-based water-repellent coating coatings similar to this product, making the Lunar Duo typical rather than exceptional in hazard profile. Higher-end manufacturers (Big Agnes, MSR, Zpacks) increasingly disclose use of fluorine-free or silicone-based waterproofing and provide chemical ingredient transparency. Lower-cost competitors offer no better assurance regarding water-repellent coating hazard; premium brands with explicit PFAS-free claims from certifiers represent a lower-concern comparative choice if water-repellent coating hazard is a concern.
If you buy it
Wash hands after setup and takedown to minimize skin contact with the water-repellent coating. Do not apply additional water-repellent treatments; re-coating typically adds PFAS exposure. Store the tent dry and unfolded when possible to reduce off-gassing in enclosed spaces. Inspect the fabric annually for coating breakdown (water no longer beads); once coating degrades, water will penetrate nylon but no additional hazard emerges. Replace the tent after 5-10 years of moderate use or if seams fail.
