Leakproof TPU Soft Cooler Backpack 20L 30-Can Waterproof Heavy-Duty Thermal Bag

Leakproof TPU Soft Cooler Backpack 20L 30-Can Waterproof Heavy-Duty Thermal Bag

Designed for outdoor camping, wild fishing, boating, beach trips, picnics, and long-distance travel, this 20L Soft Cooler Backpack features a heavy-duty TPU shell, thick thermal insulation cotton, and an airtight leakproof zipper to keep food and beverages ice-cold, fresh, or warm for hours.

Dual Hot & Cold Thermal Preservation: Constructed with inner and outer TPU layers with a thick thermal insulation cotton core to effectively lock in temperatures and slow heat exchange.

100% Airtight & Leakproof Zipper: Features a professional airtight waterproof zipper that isolates internal and external air circulation, preventing melted ice or liquid spills from leaking out.

20L / 30-Can Large Capacity Storage: Spacious main compartment holds up to 20L (approx. 30 cans), offering ample space for drinks, food, fresh catches, or ice packs for full-day outdoor excursions.

Heavy-Duty & Water-Repellent TPU Shell: Crafted with rugged TPU fabric that is highly durable, wear-resistant, completely waterproof, and easy to wipe clean after outdoor use.

Ergonomic & Breathable Backing System: Equipped with a padded sandwich mesh back panel filled with breathable, sweat-absorbing cotton to reduce fatigue and heat buildup during long carries.

MOLLE Webbing / Daisy Chains: Front-facing heavy-duty webbing loops allow easy attachment of extra gear, carabiners, bottle openers, or pouch accessories.

OEM & ODM Customization: Flexible custom manufacturing supporting multiple logo application techniques (silk screen, laser cutting, Velcro, or silicone patch) and custom colors or packaging.
