Hyperlite Mountain Gear UltaMid 4 Ultralight Pyramid Tent
Lower concern than traditional water-repellent coating tents, but brand silence on PFAS treatment leaves uncertainty.
Hyperlite Mountain Gear does not publicly disclose whether their UltaMid 4 uses PFAS-based water-repellent finishes on the silnylon fabric. Dyneema fibers themselves are Teflon-family coating-free, but the silicone and nylon layers may have received water-repellent coating treatment, standard industry practice often involves PFAS.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
