Cariloha Retreat Bamboo Sheets
Lower-concern purchase; bamboo sheets have no inherent PFAS risk, but brand transparency on finishing treatments would strengthen confidence.
Cariloha Retreat Bamboo Sheets are made from bamboo viscose, a cellulosic fiber not typically treated with PFAS in standard production. However, Cariloha makes no public disclosure about fabric finishes, dyes, or any water-repellent treatments applied post-weaving.

The full breakdown
What it's made of and why it matters
Cariloha Retreat sheets are made from bamboo viscose, a regenerated cellulose fiber produced by dissolving bamboo pulp in chemical solvents and reconstituting it into yarn. Viscose itself is not inherently toxic once the fiber is finished, though the production process uses sodium hydroxide and carbon disulfide, which are occupational hazards for manufacturers but not end consumers. The finished fabric is a soft cellulose material with no known leaching risks under normal use conditions, unlike some synthetic or ceramic-coated alternatives.
The brand's record and disclosure
Cariloha does not publish detailed chemical disclosure or third-party testing results for finishing treatments applied to these sheets. The brand markets the product as sustainable and eco-friendly but provides no certifications (such as OEKO-TEX or GOTS) that would independently verify the absence of restricted dyes, formaldehyde resins, or other textile additives. No significant safety recalls or documented chemical contamination incidents have been reported for this product line in public records.
How it compares in its category
Bamboo viscose sheets occupy the mid-market position between cheaper polyester blends and certified organic cotton. Unlike synthetic fibers, viscose has minimal microplastic shedding risk and lower static buildup. Compared to conventionally grown cotton sheets (which may carry pesticide residues), bamboo viscose typically has lower agricultural chemical exposure, though the manufacturing process itself is more chemical-intensive than organic alternatives with third-party verification.
If you buy it
Wash before first use to remove any residual manufacturing chemicals or sizing agents. Machine wash warm (not hot) and tumble dry on low to avoid degrading the fabric. Viscose is more prone to pilling and shrinkage than cotton, so gentle cycles extend life. Replace when significant pilling develops, tears appear, or the weave becomes thin; typical lifespan is 2-3 years with standard care. Do not bleach or use fabric softeners, which can degrade the fiber.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Formaldehyde resins in finishing treatments
Viscose textiles may be treated with formaldehyde-releasing resins for wrinkle resistance or sizing. Cariloha does not disclose whether Retreat sheets undergo such treatment; no independent testing is publicly available for this product.
Azo dyes and heavy metal colorants
The colored variants of these sheets could contain synthetic azo dyes or cadmium/lead pigments if not subjected to OEKO-TEX or equivalent restrictions. Brand silence on dye sourcing makes independent assessment impossible.
Residual solvents from viscose production
Properly finished viscose fabric should not leach sodium hydroxide or carbon disulfide under normal use; no reports of this hazard in commercial bamboo sheet products. Trace residues, if present, would largely be removed by initial washing.
Microplastic shedding
Viscose is a regenerated natural cellulose, not a plastic polymer, so it does not shed microplastics during washing or use like polyester or nylon would.
Antimony or heavy metals in fiber
Bamboo viscose does not inherently contain antimony or accumulate heavy metals during standard production. No documented cases of toxic metal contamination in commercial bamboo sheet products exist in public records.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
