About this cooler backpacks

Skexiod 18L Cooler Backpack

There's a gap between a squashy lunch bag and a full 30-litre picnic cooler, and the Skexiod 18L sits right in it. It's the size most solo trips and two-person days actually need: enough room in the insulated main pocket for a proper lunch, a few cans and some snacks, without the empty bulk of a bag built for a crowd.

It carries as nicely as it's sized. The back panel and shoulder straps are padded with breathable mesh, so a loaded bag doesn't leave a sweaty patch on a warm walk, and at 540 grams empty it stays light. The Oxford shell is waterproof and the PEVA lining holds the cold for hours with an ice pack.

For organisation you get two side pockets that keep water bottles upright and out of the cold zone, a front zip pocket for phone and keys, and a top grab handle alongside the straps so you can wear it or carry it by hand. If the big bags feel like overkill and a lunch bag feels too small, this is the one that fits.

Frequently Asked Questions

Who is the 18L size right for?

One or two people on a shorter outing — a day at the park, a walk, a beach afternoon. It holds a lunch plus a few cans and snacks. For a full family spread or an all-day group trip, size up to a 28–30L bag.

Does the mesh back really make a difference?

On a warm day, yes. The padded mesh panel lets a little air move between the bag and your back, so you don't end up with a sweat patch the way you would against a flat foam back.

Can I carry it by hand for short distances?

Yes — there's a top grab handle as well as the shoulder straps, so you can wear it on the walk and then lift it by the handle from car to bench without shrugging it off.

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

Skexiod 18L Cooler Backpack: the just-right middle size

3 min read Frostline

The Skexiod 18L is the bag to buy when the big coolers are too much and a lunch bag is too little. Here's how to use the size well.

Match the bag to the trip

18L is a one-or-two-person size. Pack a lunch, a few cans and some snacks and it's perfectly full; don't try to stretch it to a family picnic — that's what the 30L bags are for.

Keep bottles on the sides

Use the two side pockets for water bottles so they stay upright and out of the insulated compartment, leaving the cold space for the food and cans that actually need it.

Carry it cool

The mesh back panel does its job best when the bag isn't overloaded — pack it sensibly and the breathable back keeps a warm-weather walk comfortable.
