What Cold1 50 oz Soft Grip Tumbler is made of, ingredients and materials
The Cold1 tumbler is constructed from stainless steel, a stable alloy resistant to corrosion and leaching under normal use conditions. The soft grip is rubber, a polymer that does not typically release harmful chemicals into beverages when kept at ambient or cold temperatures. Stainless steel does not require surface coatings, glazes, or enamels that introduce lead, cadmium, or other heavy metals. The 50 oz capacity and insulation properties depend on the steel construction and internal design, not chemical additives.
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.
Rubber grip degradation
Rubber soft grips can degrade, crack, or separate over extended use or exposure to direct sunlight and heat, potentially creating choking hazards or sharp edges; no specific failure data for the Cold1 model is on record.
Bacterial growth in seams or grip interface
Seams where the rubber grip meets the steel body may trap moisture and harbor bacterial growth if not dried promptly after washing; standard care (thorough drying) mitigates this risk.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Stainless steel leaching (nickel, chromium)
High-quality stainless steel (typically 18/8 or 304 grade) used in food-contact drinkware does not leach nickel or chromium at ambient or cold temperatures under normal use; no reported incidents for this product or brand.
Microplastics
Rubber grips on stainless steel drinkware are not known to shed microplastics or particles into beverages under normal handling and storage; no established hazard in this product category.
Source, EPA ↗Coating or enamel toxicity
The Cold1 uses bare stainless steel construction without glazes, enamels, or applied surface coatings; this eliminates lead, cadmium, and coating degradation as hazard vectors.
How is this PFAS grade calculated?
The brand's record and disclosure
Reduce does not publish detailed material safety documentation or third-party certifications (such as NSF or FDA compliance statements) readily available in public sources for this product. No recalls, safety advisories, or reported contamination incidents are on record for the Cold1 line. The brand has maintained a silent stance on PFAS, which is typical for smaller beverage container manufacturers and does not indicate a safety gap given the inherent PFAS-free nature of stainless steel and rubber.
How it compares in its category
Stainless steel tumblers occupy a lower-hazard tier compared to plastic or coated aluminum alternatives, which may leach BPA, phthalates, or aluminum under acidic or heated conditions. Rubber soft grips are standard across the drinkware category and do not elevate risk relative to bare metal or silicone alternatives. No specialty coatings, finishes, or proprietary surface treatments are referenced for this model, reducing complexity and potential for degradation-related leaching over time.
If you buy it
Rinse thoroughly before first use. Use for cold and ambient beverages; stainless steel is durable at these temperatures and does not degrade. Inspect the rubber grip periodically for signs of wear, cracking, or discoloration; replace the tumbler if the grip deteriorates significantly or separates from the steel body. Hand wash or place on top rack of dishwasher; avoid prolonged exposure to extreme heat or abrasive scrubbers that could damage the grip or finish.
