Coleman Tumbler Outdoor Vacuum Insulated Water Bottle 750ml
Low risk. Vacuum insulated tumbler, typical for this type.
Stainless steel vacuum tumblers are inherently lower risk since insulation doesn't typically require fluorinated treatments. Coleman doesn't disclose PFAS details; plastic cap material remains unspecified.

What Coleman Tumbler Outdoor Vacuum Insulated is made of, ingredients and materials
This tumbler uses double-wall stainless steel (typically 18/8 food-grade) with a vacuum seal between layers, plus a plastic cap (likely polypropylene or acrylic). The stainless steel core is chemically inert and does not leach metals into cold or room-temperature beverages. The plastic cap is the only component with potential concern, but caps are typically low-contact and replaceable.
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.
Plastic cap degradation and leaching
The plastic cap may be polypropylene or acrylic. If washed repeatedly in hot water or exposed to sunlight, minor plastic degradation is possible. No specific recalls or test data for Coleman caps on record, but caps are the highest-risk component in this product.
Bacterial or mold growth in seal
The vacuum seal between the cap and tumbler can trap moisture and become a site for microbial growth if not dried thoroughly after washing. This is a maintenance issue, not a manufacturing defect, but is common to all sealed drinkware.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Stainless steel nickel content
Food-grade 18/8 stainless steel contains nickel (approximately 8 percent) but does not leach it into beverages at room temperature or in cold storage. No documented nickel-sensitivity incidents from Coleman tumblers are on record.
Heavy metals
Coleman tumblers are typically powder-coated or anodized on the exterior. No lead, cadmium, or other hazardous metal contamination has been reported in their drinkware lines. Exterior coatings do not contact beverages.

The brand's record and disclosure
Coleman is a long-established outdoor equipment maker with no major product safety recalls specifically tied to their tumbler line in recent years. The brand does not publicly disclose detailed material sourcing or third-party testing results for most consumer drinkware. No documented formaldehyde, heavy-metal, or leaching controversies are on record for this product category from Coleman.
How it compares in its category
Stainless steel vacuum tumblers are among the lowest-risk drinkware options; they avoid ceramic glaze hazards, Teflon-type coating coatings, and aluminum leaching. Coleman's offering is typical for outdoor-grade tumbler design and pricing. Comparable brands (Hydro Flask, YETI, Thermos) use identical construction with similar safety profiles.
If you buy it
Hand-wash the cap regularly to prevent mold or bacterial growth in the seal; do not run it through high-heat dishwashers repeatedly, as this can degrade the plastic cap over time. Do not leave acidic beverages (lemon water, vinegar solutions) standing for extended periods, though stainless steel is generally resistant. Replace the cap if it becomes cracked or develops persistent odors. The vacuum seal itself is durable and unlikely to fail under normal use.
