YETI 3L Daytrip Lunch Box
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes rotomolded polyethylene, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What YETI 3L Daytrip Lunch Box is made of, ingredients and materials
The YETI Daytrip is rotomolded polyethylene (HDPE or similar density PE), a thermoplastic created by heating plastic powder in a rotating mold until it fuses into a seamless, durable shell. This manufacturing process does not introduce vinyl chloride, BPA, or phthalates as processing aids. Rotomolded PE is approved for food contact under FDA guidelines and shows lower concern for leaching estrogens or plasticizers under normal cold food storage conditions. The material's closed-cell structure and thickness make it resistant to microplastic shedding, even with moderate wear.
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.
Microplastics
Heavy abrasion or prolonged UV exposure may cause microscopic PE particle shedding from the outer surface; risk is low during normal food storage but increases if the box is used as a seat or subject to rough handling over years.
Source, EPA ↗Mold and bacterial growth in seals
Gasket materials (typically silicone or rubber) and the seal groove are prone to mold if the box is not dried completely after washing. This is a hygiene issue, not a leaching hazard, but can render the box unsafe for cold food storage if not maintained.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
Rotomolded polyethylene does not require BPA as a monomer or phthalates as plasticizers in its manufacturing. No evidence of these additives in YETI's food-contact PE products.
Source, FDA ↗Leaching from gasket or closure materials
YETI does not disclose the specific elastomer formulation in gaskets; however, silicone and standard food-grade rubber are not known to leach into cold foods under normal storage conditions. No recalls or contamination events are on record.
Off-gassing of volatile organic compounds (VOCs)
Rotomolded PE products typically emit minimal VOCs compared to foam-lined or adhesive-sealed containers. The seamless construction and lack of glues minimize this risk in the Daytrip model.
The full breakdown
The brand's record and disclosure
YETI is known for transparent material disclosures and third-party testing across its product lines. The brand has published safety data sheets for food-contact products and maintains certifications including FDA compliance for food storage containers. No recalls involving chemical leaching or coating degradation are on record for this model. The brand's silence on PFAS reflects the product design (no added coatings or water-repellent treatments named), not evasion.
How it compares in its category
Rotomolded PE lunch boxes show lower concern compared to thin plastic boxes with unknown coatings or metal containers with epoxy liners that may contain BPA. The Daytrip's seamless construction avoids glued seams where volatile off-gassing can occur. Price point places it above budget coolers (which sometimes use recycled plastic with unknown contaminants) but within the category standard for insulated food storage without premium certifications like stainless steel alternatives.
If you buy it
Store cold foods and avoid temperatures above 160F (70C); rotomolded PE softens under prolonged heat. Wash with warm soapy water and dry completely to prevent mold in seals and gaskets; do not soak or use abrasive cleaners. Replace gaskets if they crack or fail to create an airtight seal. The plastic will develop minor surface scratches and discoloration over years of use, which is cosmetic and does not compromise food safety or structural integrity.
