Designed for the active Australian lifestyle, this hands-free cooling solution allows you to carry refreshing drinks and fresh food to the beach, bush, or construction site without the hassle of a heavy handheld esky. Whether you are planning a family picnic or a hiking trip, this backpack keeps your essentials at the perfect temperature.
Key Features
- Excellent Insulation: Engineered with a multi-layer design including durable Oxford cloth and a thick PEVA lining to keep items cold for approximately 5-6 hours or warm for 3-4 hours. Adding ice packs (not included) can extend cooling time significantly.
- Leakproof Interior: The inner lining features waterproof EVA material using a closed-cycle thermal insulation process, ensuring that melted ice or condensation does not leak out and soak your back.
- Spacious Capacity: With a generous volume of approximately 20.5 litres, this bag can easily hold beverage bottles, lunch boxes, fruit, and snacks, making it suitable for family outings or long shifts at work.
- Comfortable & Durable: Weighing only 430g, it features adjustable padded shoulder straps for comfortable carrying. The exterior is made from scratch-resistant and wear-resistant fabric designed for outdoor use.
- Organised Storage: Includes a large main compartment, a front vertical zipper pocket for small essentials like cutlery or phones, and side mesh pockets perfect for holding wine bottles, umbrellas, or water flasks.
Product Description
Say goodbye to bulky hard coolers and embrace the ease of this soft-sided cooler backpack.

Cleaning is effortless thanks to the wipe-clean interior lining. If a spill occurs, simply use a damp cloth to wipe it away.
