Bunker Cool Box, 42L

Serious performance. Easier to carry.

The Bunker 42L Cool Box is the compact sibling in the BUNKER limited edition range — delivering the same rotomolded durability, five-day ice retention, and premium feature set as the 66L, in a lighter, more manageable package. For solo adventurers, couples, day-trippers, and anyone who wants high-end cool box performance without the bulk, the 42L hits the sweet spot between capacity and portability.

5-Day Ice Retention. No Compromises.

Don't let the smaller footprint fool you. The Bunker 42L features the same high-quality thick-wall insulation as its larger counterpart, maintaining ice for up to five full days in real outdoor conditions. Whether you're heading out on a weekend kayaking trip, loading up a boat for a day on the water, or stocking a basecamp for a few nights under the stars, the Bunker 42L keeps food fresh and drinks cold far beyond what a standard cool box can manage. The no-sweat exterior ensures the outside stays dry, protecting surfaces and surrounding gear from condensation.

Rotomolded for the Long Haul

Rotational moulding creates a seamless, one-piece shell that is fundamentally stronger and more impact resistant than injection-moulded or standard fabricated cool boxes. It's a construction method borrowed from the premium end of the outdoor equipment market — and it shows in everyday use. The Bunker 42L shrugs off the bumps, drops, and rough handling of genuine outdoor adventures without losing its shape or its ability to hold temperature. UV resistance protects the exterior from sun degradation over years of outdoor exposure.

Built Tight. Built Right.

Two heavy-duty interlocking latches create a secure, pressure-sealed lid close that keeps the cold in and the water out — fully leakproof throughout. The stainless steel latch hardware pulls double duty as a built-in bottle opener, a practical touch that will get used every time. A built-in pressure release valve makes the lid easy to pop open after extended sealed use, and a recessed drainage plug at the base makes emptying meltwater quick and clean. Non-toxic materials make it safe for all food and drink applications.

Compact Enough to Go Anywhere

At 11.9kg and with a footprint of W690 x D420 x H429mm, the Bunker 42L is genuinely portable in a way the larger 66L isn't. A robust carry handle with a comfortable grip makes single-handed transport straightforward, whether you're loading it onto a boat, carrying it to a campsite, or getting it in and out of a vehicle. Non-slip feet keep the box planted on smooth or wet surfaces, and integrated tie-down anchor points allow it to be secured firmly to a boat deck, trailer, or truck bed when you're on the move.

Limited Edition — Available While Stocks Last

The Bunker 42L is part of a limited edition release and won't be restocked once it's gone. If you've been looking for a premium rotomolded cool box at this size — one that genuinely delivers on its performance claims — this is the one worth picking up before it disappears.
