About this cooler backpacks

GartWerk 48-Can Cooler Backpack

When the answer to 'how many are coming?' is 'lots', the GartWerk is the bag. It's the largest cooler in the range — a 30-litre body that holds up to 48 cans — and it's organised for a group rather than a solo lunch, with two insulated compartments so you can keep drinks and food in their own zones instead of one big jumble.

The insulation is multi-layered with a silver PEVA lining, giving it a twelve-hour cold hold with ice packs, or around six hours for hot food if you pack a warm dish. Seams are hot-pressed and leakproof, so even a big melting load of ice stays contained. It's water-resistant Oxford outside, and at 1.1kg empty it's the heaviest bag here — but that's the trade for carrying a whole group's day.

The details are built around a proper picnic. A dedicated holder straps your rolled picnic mat to the bag so the blanket comes along without a second bag; a daisy-chain webbing panel on the front takes clip-on extras; there's a big front pocket and two side mesh pockets for cutlery, cups and bottles; and the zip pull cleverly doubles as a bottle opener. For barbecues, family gatherings and big beach days, nothing else here carries as much as tidily.

Got questions?

Frequently Asked Questions

Is 48 cans realistic or a best-case number?

Forty-eight is the drinks-only maximum. In real use you'll mix cans with food tubs and ice packs, so treat it as a genuine group-sized bag — a big family day or a barbecue for friends — rather than literally 48 drinks.

Can it keep hot food warm as well as cold drinks cold?

Yes. Use the two compartments: cold drinks with ice packs in one, a hot dish in the other. It holds cold for up to 12 hours and hot for around 6, so it's genuinely a both-temperatures bag for a group.

How does the picnic-mat holder work?

It's a holder on the bag that straps a rolled-up picnic blanket in place, so the one thing that never fits inside a cooler finally travels with it. Roll the mat, secure it, and your hands stay free for everything else.

Do you deliver, and how long does it take?

Yes. Your delivery estimate for your address is shown at checkout before you pay, so you can see the timing first. Delivery is free UK-wide on orders over £30, with a flat £3.99 charge under that.

Can I return it if it isn't right?

Yes — you can return it in line with our returns policy for a refund. Keep the packaging where you can, as it makes the return tidier, and get in touch and we'll help.

The complete guide

GartWerk 48-Can Cooler Backpack: the group-sized carry-it-all

3 min read Frostline

The GartWerk is the bag for the day when everyone's invited. Here's how to run the biggest cooler in the range.

Use the two zones for a group

Keep all the cold drinks and ice packs in one compartment and the food in the other — with a group's worth of stuff, that separation is what stops it becoming an unmanageable jumble you have to dig through.

Spread the ice for 48 cans

A single ice pack won't cool a full 30L load. Layer several ice packs through the drinks so the top cans are as cold as the bottom, and it'll hold the full twelve hours.

Let it carry the blanket

Strap your rolled picnic mat into the holder so the blanket travels with the food, clip any extras to the daisy chain, and you'll genuinely move a whole group's picnic in one trip.
