CLY036
Introducing the 31L 8mm Insulated Outdoor Cooler Tote Bag, a high-performance thermal carrier engineered for extended outdoor adventures and heavy-duty cooling needs. With a spacious 31.2-liter capacity (40cm x 26cm x 30cm), this bag comfortably accommodates all your picnic essentials, grocery hauls, or catering supplies.
The core of its exceptional performance lies in the advanced 3-layer insulation system:
Outer Layer: Water-resistant mesh fabric—customizable in color and material—provides durable protection against rain, snow, and tearing while remaining easy to clean.
Middle Layer: 8mm thickened pearl cotton creates a dense thermal barrier, significantly extending insulated and cooling times compared to standard insulated bags.
Inner Layer: Seamless aluminum foil lining reflects internal temperatures and prevents leaks, ensuring melted ice stays contained and food contact surfaces remain hygienic.
Every detail is designed for reliability in demanding environments. The waterproof zipper and sealed construction prevent temperature loss and moisture ingress, while the removable padded shoulder strap offers versatile carrying options—handheld or over-the-shoulder—with reinforced stitching for heavy loads. Inside, a built-in mesh pocket on the lid organizes ice packs, utensils, or napkins, and the structured upright design keeps the bag stable and accessible during use.
Fully customizable with your brand logo via OEM options (rubber patches, embroidery, screen printing), this cooler tote is the ultimate choice for outdoor brands, catering services, or anyone who demands serious thermal performance in a portable package.

Why Choose Us
Professional-Grade 3-Layer Thermal Architecture:
We engineer for extreme temperature challenges. This cooler features an advanced 3-layer insulation system—a water-resistant mesh exterior, an 8mm thickened pearl cotton core, and a seamless aluminum foil liner—creating a dense thermal barrier that significantly extends cooling time far beyond standard insulated bags.
Engineered for Serious Capacity and Sustained Performance:
We design for those who pack for a crowd, not just themselves. With a massive 31.2-liter capacity, this bag holds everything from camping provisions to catering supplies. The 8mm insulation layer ensures your ice stays frozen and your perishables stay fresh through long days in the sun.
Leakproof Integrity from Base to Zipper:
We prioritize containment as much as cooling. The fully sealed construction includes a waterproof zipper and a seamless aluminum foil inner liner, creating a leakproof vessel that contains melted ice and prevents moisture from compromising your car trunk or picnic blanket.
Built for the Demands of the Outdoors:
We select materials that thrive in rugged environments. The customizable water-resistant mesh exterior shrugs off rain, snow, and abrasion, while the removable padded shoulder strap with reinforced stitching offers versatile, comfortable carry options for heavy loads over long distances.
Intelligent Organization Inside and Out:
We believe even a cooler should be thoughtfully organized. The built-in mesh pocket on the lid keeps ice packs, utensils, and napkins accessible without digging through the main compartment, while the structured upright design ensures the bag remains stable and easy to pack during use.
Direct Value in Heavy-Duty, Brandable Performance:
Our model makes this premium, large-capacity cooler tote an accessible investment for outdoor brands and serious adventurers. We deliver a product where value is measured in its industrial-grade insulation, professional construction, and its ability to perform reliably on the most demanding excursions.
How does the 3-layer insulation system work, and why is 8mm significant?
The system combines three functional layers: the outer mesh provides durable protection, the 8mm thickened pearl cotton middle layer creates a dense thermal barrier that dramatically slows temperature transfer, and the inner aluminum foil reflects internal temperatures. The 8mm thickness is significantly more than standard insulated bags, resulting in much longer cooling performance.
What can I realistically pack in 31.2 liters of capacity?
This capacity is designed for serious group outings. It can comfortably hold 24+ standard cans with ice, multiple large food containers, several water bottles, or a full picnic spread for 4-6 people. It's also perfect for bulk grocery trips, transporting catering orders, or keeping provisions cold for a full day of camping.
How leakproof is the construction, really?
The combination of a waterproof zipper, sealed seams, and a seamless aluminum foil liner creates a genuinely leakproof vessel. You can confidently pack melted ice, leaky drink bottles, or thawing items without worrying about messes in your car, backpack, or on your picnic blanket.
Is the water-resistant mesh exterior durable enough for outdoor use?
Absolutely. The mesh fabric is selected specifically for its balance of lightweight breathability and rugged toughness. It resists tearing, sheds rain and snow, and is easy to wipe clean after muddy or sandy adventures. Plus, it's fully customizable in color and material to match your brand's outdoor aesthetic.
What is the benefit of the removable padded shoulder strap?
The removable padded strap offers versatile carry options for different situations. Use it as a crossbody or shoulder bag for longer treks to distribute weight comfortably, or remove it for quick handheld trips from the car to the picnic spot. The reinforced stitching ensures it can handle the bag's full heavy load.
What is the production lead time for a custom-branded bulk order?
For a bulk order of this high-performance cooler tote with custom branding (rubber patches, embroidery, or screen printing), our standard production and delivery timeline is 25-30 days from final artwork confirmation. This ensures proper assembly of the multi-layer insulation system and high-quality logo application.
