Hyperlite Mountain Gear Ultralight Dyneema Tarp for Hiking & Backpacking
Ultralight tarps typically use water-repellent coating treatments; Hyperlite coating source and PFAS status undisclosed; contact them directly before buying.
Hyperlite Mountain Gear's Dyneema tarps are marketed for weight and durability but offer no public disclosure of their water-repellent coating chemistry or PFAS content. The applied water-repellent coating finish is a common vector for PFAS like C6 and C8 fluorocarbons.

What Hyperlite Mountain Gear Ultralight is made of, ingredients and materials
Dyneema is a high-molecular-weight polyethylene fiber known for exceptional strength-to-weight and water resistance without fabric coating. However, ultralight tarps require a water-repellent coating (water-repellent coating) topcoat to shed water effectively. Hyperlite has not publicly disclosed the chemical identity of their water-repellent coating treatment, which is the primary concern for this product. Dyneema itself is chemically stable polyethylene and does not off-gas formaldehyde or release heavy metals under normal use.
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 water-repellent coating is the primary hazard; fluorinated (PFAS) chemistry is industry standard for ultralight tarp durability, but Hyperlite has not confirmed or ruled this out. Contact the manufacturer before purchase if PFAS exposure is a concern.
Source, ATSDR ↗What’s reassuring
Seam sealant leachables
Dyneema tarps typically use polyurethane or silicone sealants on seams; Hyperlite does not disclose sealant type. No incidents reported, but seams can off-gas volatile organics if poorly cured. Proper ventilation during first use mitigates this.
Microplastic shedding from fibers
Dyneema fiber does not readily shed microplastics under normal mechanical stress or weathering. No evidence of shedding from Hyperlite tarps during outdoor use.
Formaldehyde / VOCs
Dyneema fibers and modern polyester thread do not intrinsically require formaldehyde resins. No records of formaldehyde releases from Hyperlite tarps.
Source, ATSDR ↗Flame retardants
Ultralight tarps are not treated with flame retardants; Dyneema itself has low flammability. No hazard in this category.

The brand's record and disclosure
Hyperlite Mountain Gear has not published material safety data sheets, chemical composition statements, or PFAS certifications for their tarps. The company has not publicly addressed whether their water-repellent coating uses fluorinated (PFAS) chemistry or non-fluorinated alternatives. This silence is notably different from brands like Big Agnes and Zpacks, which have begun disclosing water-repellent coating sources in response to PFAS scrutiny. No recalls or health incidents involving Hyperlite tarps are on record.
How it compares in its category
Most ultralight tarps (Zpacks, Hyperlite, Three Peaks) use Dyneema or Cuben film and face the same water-repellent coating opacity problem. Zpacks has stated they use DuPont Teflon (Teflon-type coating-based, PFAS-laden); Hyperlite has not. Non-fluorinated water-repellent coating alternatives exist (silicone-based, wax-based) but add weight and durability trade-offs. Hyperlite's silence places it in the category of products where PFAS status cannot be verified by consumers.
If you buy it
Contact Hyperlite directly and request their water-repellent coating treatment name and PFAS certification before ordering. During use, keep the tarp away from direct skin contact in wet conditions if PFAS concerns matter to you. Dyneema does not degrade under UV or temperature stress within typical camping ranges, but inspect seams and stitching annually for wear. Store dry to prevent mold; do not machine wash. Rinse with plain water and air dry only.
