Arctic Zone · Insulated Drink Tumblers
20 oz Arctic Zone Titan Thermal Hp Travel Tumbler (Matte Navy)
Thermal tumbler with unknown waterproof coating; PFAS risk remains unclear.
Arctic Zone does not disclose coating composition or PFAS status for this tumbler. Waterproof thermal tumblers often use water-repellent coating treatments that may contain PFAS, but brand transparency is absent.

Material
Stainless steel exterior with waterproof internal coating (unspecified)
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Undisclosed waterproof coating composition
Internal waterproof coating is not specified on product labels or technical sheets. If Teflon-type coating-based or Teflon-family coating-based, PFAS exposure is possible; if silicone or polyurethane, risk is lower. Manufacturer silence prevents definitive assessment.
Coating degradation and microleaching over time
Polymer waterproof coatings on tumbler lids and seams can crack or peel with repeated hot-water washing and thermal stress. Degraded coating may shed particles into liquids; risk increases after 2-3 years of heavy use.
What’s reassuring
Lid gasket/seal materials
Lid gaskets are typically silicone or rubber; no specific composition is disclosed for this model. Standard silicone gaskets carry minimal chemical leaching risk under normal use.
Stainless steel leaching
Food-grade stainless steel (typically 18/8 or 304) does not leach nickel, chromium, or other metals into cold or moderately hot beverages. No hazard is established for this product category when using standard steel alloys.
Paint or powder coat on exterior finish
The matte navy exterior finish is not food-contact material. Standard powder coats and paints used on drinkware carry negligible risk of migration to beverages.
The full breakdown
What it's made of and why it matters
The Arctic Zone Titan has a stainless steel exterior, which is chemically stable and does not leach metals under normal use. The critical unknown is the internal waterproof coating, Arctic Zone does not specify whether it uses Teflon-type coating (Teflon), silicone, polyurethane, or another polymer. This coating is essential for preventing liquid seepage through the lid and seams, but its composition directly determines whether PFAS or other synthetic chemicals are present. The matte navy finish on the exterior appears to be a powder coat or paint, a standard application that carries minimal direct food-contact risk.
The brand's record and disclosure
Arctic Zone (part of the Coleman/Newell Brands portfolio) does not publicly disclose waterproof coating chemistry on product pages or safety documentation reviewed here. The brand has not published PFAS-free certifications or phase-out commitments. No major safety recalls specifically tied to this tumbler model have been reported in public databases. The silence on coating materials is a transparency gap typical of mid-market drinkware brands, but not unusual; premium competitors (Hydro Flask, Yeti) similarly withhold coating specifics from consumer-facing materials.
How it compares in its category
Travel tumblers in this price tier (budget to mid-range, typically $15-40) almost always use waterproof coatings on internal seams and lids; few disclose the chemistry. Stainless steel bodies are the category standard and are safe. The Titan's 20 oz capacity and insulation design are unremarkable. Competitors like Contigo, Thermos, and Zojirushi similarly do not advertise coating composition, making this product representative of the category's transparency problem rather than an outlier.
If you buy it
Do not expose the tumbler to prolonged boiling water (above 160 degrees F regularly) as this can stress polymer coatings. Hand wash rather than dishwasher; high heat cycles may degrade the waterproof layer over years of use. Inspect seals and lid gaskets annually; if cracking appears, coating degradation is underway and replacement is advisable to avoid potential microleaching. Contact Arctic Zone directly to request the formal name and PFAS status of the waterproof coating; this information should be available to consumers even if not advertised.
