Burrow Top Quilt
Skip until brand discloses water-repellent treatment composition.
Burrow Top Quilt likely uses water-repellent coating for water resistance, but Hammock Gear does not publicly disclose the chemistry or PFAS status. No independent verification available.

What Burrow Top Quilt is made of, ingredients and materials
The Burrow Top Quilt uses synthetic insulation, likely polyester or nylon-based, which is standard for down-alternative quilts. The hazard centers on the water-repellent coating applied to the outer shell, Hammock Gear has not publicly disclosed whether this treatment contains PFAS (per-/polyfluoroalkyl substances) or other persistent chemicals. Synthetic insulation fibers themselves can be treated with formaldehyde-based resins during manufacturing to improve loft retention and durability, though this is not confirmed on record for this model.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Category baseline

No PFAS disclosure
No public statement from the brand about PFAS in this product.
Undisclosed water-repellent coating (presumed fluorinated)
Synthetic outdoor quilts almost universally use water-repellent coating (water-repellent coating) treatments; PFAS-containing water-repellent coating is the historical standard. Hammock Gear's refusal to disclose means PFAS presence is likely but unconfirmed. This coating migrates into skin contact, laundry water, and the environment over time.
Formaldehyde / VOCs
Polyester and nylon fibers in synthetic insulation can be finished with formaldehyde-releasing resins to stabilize loft. No record of Hammock Gear confirming or denying this practice. Off-gassing during storage or use is typically low but prolonged direct skin contact with untreated synthetic insulation may release trace formaldehyde.
Source, ATSDR ↗Coating degradation and particle release
Outdoor quilts subjected to UV, washing, and compression naturally degrade water-repellent coatings over 2-5 years of use. Peeling or flaking water-repellent coating coatings can shed microparticles; if fluorinated, these become a secondary route of PFAS ingestion and environmental release.
What’s reassuring
Flame retardants
No public evidence that Hammock Gear applies flame-retardant treatments to this quilt. However, some synthetic insulation producers add brominated or phosphorus-based flame retardants during fiber production; Hammock Gear does not confirm or deny this for any product.
Source, EPA ↗Azo dyes in colored outer shells
If the quilt uses synthetic fabric with printed or dyed colors, azo dyes could be present; however, no public records indicate Hammock Gear uses problematic azo dye suppliers. The outer shell fabric composition itself is not disclosed.
How is this PFAS grade calculated?
The brand's record and disclosure
Hammock Gear does not publish material safety data sheets, water-repellent coating formulations, or PFAS testing results for any of its quilts or gear on its website or in response to common inquiries. The brand's silence on chemical treatment disclosure is notable in a category where competitors (e.g., some premium outdoor brands) have begun listing PFAS-free or fluorocarbon-free certifications. No recalls or established safety controversies are on record for Hammock Gear products, but the lack of transparency is itself a red flag for consumer risk assessment.
How it compares in its category
Synthetic-insulated quilts are a middle ground between down (which requires less chemical treatment) and fully treated synthetic alternatives. Many budget and mid-range brands similarly avoid disclosure of water-repellent chemistry, making this common, not unique, in the price range. Some outdoor brands now explicitly market PFAS-free or fluorocarbon-free synthetic quilts; Burrow's lack of such messaging suggests either standard fluorinated treatment or indifference to disclosure, neither of which reduces chemical risk.
If you buy it
Do not purchase until Hammock Gear discloses the composition of the water-repellent coating. If you already own one, use it as-is; heat during normal use or washing will not cause significant offgassing of synthetic insulation fibers. Wash infrequently in cool water with mild detergent to minimize leaching of coating residues, and air-dry to avoid high heat that could degrade synthetic fibers. Replace if visible coating degradation, peeling, or loss of water repellency occurs over years of heavy use.
