What Marmot Slate All Day Travel Bag is made of, ingredients and materials
The Slate All Day uses a nylon/polyester blend with a water-repellent coating (water-repellent coating) coating applied to the outer fabric. water-repellent coating treatments historically relied on perfluorinated compounds (PFAS) for water-beading performance, though some newer alternatives exist. The nylon and polyester fibers themselves are chemically stable and pose no inherent leaching risk during normal handling; the coating is the point of concern for chemical exposure, both to the wearer and to manufacturing environments.
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.
water-repellent coating degradation and inhalation risk
If the water-repellent coating treatment uses legacy PFAS compounds, mechanical wear or heat exposure (e.g., washing, storage near heat sources) may liberate coating particles. The risk is low under normal use, but unknown treatment chemistry prevents definitive exclusion.
Volatilizing organic compounds (VOC) from adhesives and finishes
Seam sealing, fabric bonding, and water-repellent coating application involve adhesives and solvent carriers that may off-gas in the first weeks of ownership. This is a normal low-level risk for new synthetic travel gear; ventilation mitigates it rapidly.
What’s reassuring
Formaldehyde / VOCs
No formaldehyde-resin finishes are standard in nylon/polyester travel bags. Marmot has not disclosed any wrinkle-resistance or antimicrobial finishes on this model, so formaldehyde risk is not established for this product.
Source, ATSDR ↗Azo dyes and synthetic colorants
The Slate colorway (gray/charcoal) does not indicate use of restricted azo dyes in available product documentation. Marmot does not publish dye supplier certifications for this line, but no recall or contamination has been reported for azo dyes in Marmot bags.
Heavy metals
No heavy-metal contamination has been reported in Marmot travel bags. The nylon and polyester base materials do not typically accumulate or leach metals without intentional inclusion (e.g., antimony in polyester fibers), which is not disclosed for this product.

The brand's record and disclosure
Marmot (owned by Wolverine World Wide) has not published a public PFAS phase-out timeline or commitment to PFAS-free water-repellent coating treatments, unlike brands such as Patagonia and Arc'teryx. The company offers no material safety data sheets or transparency reports for this specific bag. This silence is notable in an industry where outdoor and travel gear brands increasingly disclose treatment chemistry in response to environmental and health scrutiny.
How it compares in its category
Travel bags in this price and performance tier typically carry similar water-repellent coating-treated synthetic materials; few brands disclose treatment chemistry at the consumer level. Marmot's lack of transparency puts this bag behind competitors who offer PFAS-free certifications or third-party testing. However, the bag's core nylon/polyester construction is standard and not inherently riskier than alternatives; the differentiation is entirely in coating accountability.
If you buy it
Handle and store the bag in a well-ventilated space during the first week to allow off-gassing of any manufacturing residues. Avoid prolonged skin contact with the water-repellent coating-treated exterior until you are confident the treatment is stable. Clean the bag with mild soap and cool water only; do not dry-clean or expose to heat, which may degrade the coating and release chemical residues. Replace or retire the bag if the water-repellent coating noticeably peels, flakes, or loses water-beading function, as degraded coating particles may concentrate contaminants.
