Features of Our Coolers

Durable & Travel-Ready Construction
Crafted from ultra-impact-resistant EPS foam, our coolers withstand rugged travel demands while remaining lightweight. Advanced thermal insulation maintains internal cold temperatures for exceptionally long periods, making it perfect for preserving chilled foods, beverages, and perishables when combined with ice packs or cubes.

Superior Temperature Retention
Engineered with high-efficiency thermal barriers, these coolers keep contents ice-cold for 24-48 hours and maintain warmth for 6-8 hours. Maximum thermal performance is achieved when pre-chilled and used with adequate ice packs – ideal for extended outdoor adventures or critical temperature-sensitive storage.

Versatile Capacity Options
Choose from 5L to 80L sizes to match any need – from personal lunch storage to group event provisioning. These high-performance insulated boxes outperform standard cooler bags, making them ideal for camping excursions, picnic trips, catering operations, and professional food transportation.

Ergonomic Transport System
Strategically positioned side handles ensure comfortable carrying with balanced weight distribution. The integrated fold-out handle enables smooth rolling transportation across various terrains, reducing physical strain during movement. Robust construction prevents flexing even when fully loaded.

Multi-Purpose Outdoor Companion
Perfect for camping, fishing trips, beach parties, and daily work commutes. Excellent for long-haul road trips, extended campsite stays, sports tournaments, and outdoor festivals. Doubles as emergency cold storage during power outages and serves professional healthcare transportation needs.
Types of Coolers

Hard-Sided Coolers
Plastic is the preferred material for crafting durable, high-quality hard-sided coolers. Among the finest ice chests available, rotomolded coolers stand out. Made from a single seamless plastic piece, they offer superior strength and are waterproof and leakproof.

Soft-Sided Coolers
Fabric coolers are typically collapsible for easy storage. These lightweight, portable options are ideal for short trips like picnics or beach outings. Features often include wheels, telescoping handles, padded grips, exterior bungee cords, and mesh pockets for small items.

Patio Coolers
For backyard use, consider stationary or wheeled outdoor patio coolers. Designed for convenience with raised access to contents, they come in various decorative styles. Some feature locking casters. Buffet-style models offer a cooler section, storage cabinets for essentials, and a serving countertop.

Insulated Backpack Coolers
These provide hands-free carrying. Some feature built-in drain plugs; others require tilting to empty. Many include convenient dry storage compartments for picnic essentials like plates and utensils.

Frequently Asked Questions about Cooler
The suitable cooler size depends on your group size and trip duration. For a weekend with two to three people, coolers from 25 to 45 quarts are recommended. For families and longer stays, a 45 to 70 quart capacity is more suitable. Alternatively, you can split items between two medium coolers, often a preferred option.
A box cooler’s principle is simple; cooled water is circulated forcibly through a U-tube bundle, placed in a sea chest with inlet and outlet grids.
It’s ideal for camping or festivals where parking is distant. Plus, effective insulation can keep food cold for days. We filled ours with food, drinks, and ice; everything stayed chilled 36 hours later.
Following our advice, a cool box can be effective for 24-48hrs. That said, larger versions typically provide 2 days of cooling.
A cooler box keeps all drinks—beer, water, soft drinks, other liquids—and food items fully chilled and fresh.
An electric cooler box is a temperature-regulated unit powered electrically. It keeps the interior cooler than the exterior to maintain food and drink freshness.
Generally, solid sides and superior insulation make a coolbox outperform a coolbag. The bag has better packability. Boxes are bulky and non-compressible. Their shape can hinder carrying, hence some have wheels.
Cleanup is easy: drain water, wipe down, and air dry. Clean before use with a damp cloth and mild soap. Ensure it’s dry for storage or travel.
Ensure enough ice keeps food at 40 °F (4.4 °C) or below. Add more ice as it melts. A full freezer maintains temperature about 48 hours (24 hours if half full).
The ideal cool box temperature matches a fridge: 2 to 6 °C. It stays ideal if cooled properly, kept shaded, and monitored. A cool box keeps food cool on every trip.
