YETI Daytrip® "Lunch Bag" 6 l Cool Bag 1 piece

A cold lunch that survives a day next to the car

What is the YETI Daytrip 6L cool bag? An upright cool bag for a day out that opens one-handed via a magnetic strip and holds nine cans. Not meant for a whole weekend, not for submerging and not for going upside down in a backpack.

The YETI Daytrip 6L cool bag is YETI's lunch bag for people who pack their food the night before and want it still cold at midday at the folding table next to the car. It stands upright instead of lying flat, opens one-handed and has two outer pockets for everything that doesn't need to be cold. Six litres, one size, eleven colours.

Quarter past six, the car park is still half empty, the night's damp hanging over the bonnets. Tailgate up, folding table out, bag next to it. At two, when half the crowd is already back on the motorway and the other half is queuing at the bratwurst stand, you open it a second time. And it's still lunch.

• Opens one-handed, closes one-handed. The MagSnap closure is a strip of hidden magnets. You hold your coffee in one hand and open the bag with the other, without putting it down. No zip that snags halfway, no Velcro that stops gripping after two seasons.
• It stands instead of lying down. At 26.2 centimetres tall, a water bottle fits in upright, with three food containers next to it. If you load drinks instead, you'll get nine 0.33 litre cans in. Nothing tips, nothing rolls, nothing gets squashed, because the base and lid are moulded to hold their shape.
• Two outer pockets for everything that doesn't need to be cold. A flat pocket at the front held shut by a single magnet, and a zipped one at the back. Cutlery, napkins and the spare key go there, not between the sandwiches. On the back there's also a HitchPoint grid for clipping things on.

Detailing1's tip from the shop: A cool bag doesn't cool anything down, it only holds what you give it. Pack room-temperature sandwiches at half five in the morning and you've lost the day before you've even set off. The ice pack goes in the freezer the night before, the food goes straight from the fridge into the bag in the morning, and then it stays shut.

Germany's Federal Institute for Risk Assessment sets a maximum of 7 °C for highly perishable food. A bag extends that cold chain, it doesn't start it. The second trick costs nothing: pack it full. A half-empty bag is the worst state to drive it around in all day. Better one more bottle of water in there than air.

The evening before decides the lunch after

The Daytrip gets packed in the evening, not the morning. Five minutes in the kitchen, a frozen ICE Sheet flat on the bottom, and tomorrow is sorted.

For this format, YETI recommends one medium ICE Sheet or one to two small ones. The sheets lie flat and take up barely any space, unlike loose ice, which melts and pools at the bottom. On top goes the actual contents: according to a hands-on test, three food containers fit in, plus a bottle standing upright, and there's still room to spare.

In the morning you grab it by the handle, put it in the footwell behind the driver's seat and head off. If you need both hands free because the folding table, camera and camping chair are coming too, clip on the separately available Daytrip shoulder strap. That's the difference between a bag you carry and one you just bring along.

The outer pockets are the part you only come to appreciate the third time round. Up front, under the single magnet, go cutlery and napkins. At the back, in the zipped compartment, the spare key. Only what needs to stay cold goes inside, and the matching YETI Food Storage containers in Small and Medium stack in there without gaps.

And then it stays shut. Every opening costs you cold time, and at a meet where someone comes over every twenty minutes to ask about your paint, it's easy to open a bag like this four times too often. Once in the morning, once at midday, and in between it sits in the shade. For the coffee alongside, use the insulated tumbler that rides in the cup holder anyway.

Upright or flat is the real decision

The 6 litre bag stands upright, the 5 litre box lies flat. That's the whole difference between the two Daytrip models, and it matters more than the litre on the label.

It sounds the wrong way round: the flat Daytrip Lunch Box with 5 litres takes ten cans, the higher-built 6 litre bag only nine. If you're stacking drinks and need space under the boot floor or the passenger seat, take the box. If you're carrying food, take the bag: salad stays in its container, the bottle stands instead of rolling, and when you open it you can see into the whole bag from above.

That same height is also the most common criticism of the bag. At 26.2 centimetres it's too tall for many office fridge shelves — the tests say so, and it regularly annoys people. If you want to put it in the office fridge during the week, measure first. In the car, the same number is an advantage, because the bag stands up in the footwell on its own.

The second honest point is about the closure. On this bag the inner liner is leakproof, the MagSnap isn't — and YETI says so itself. A tipped-over drink stays in the liner, but upside down in a backpack won't work, and it has no business under water. In heat and muggy air, the outside can get damp, so put something underneath it on leather.

And it tops out early. YETI never gives an hours figure; what's documented is a hands-on test in which salad and yoghurt were still cool after almost five hours in the car, without any ice pack at all. With an ice pack it's more, but it won't be a weekend. If the trackday runs over two days, the Hopper Flip 12 with its sealed zip is the right choice.

After three seasons in the boot, it barely shows

The reason there's a YETI on the folding table in this scene and not the bag from the discount flyer isn't the cooling performance. It's how it ages.

A cool bag in a car doesn't lead a sheltered life. It rides along next to the toolbox, stands on hot tarmac in summer, gets wet and dusty and chucked in somewhere all the time. That's exactly where cheap bags fall apart: the seams pull, the liner cracks, the closure goes slack, and after two summers you can smell the thing from two metres away.

Instead of a zip edge, the Daytrip has a magnetic strip; instead of a glued-in film, a tight inner liner; and a moulded shell top and bottom. YETI gives this bag a three-year warranty, not the five years of the Rambler drinkware. After three seasons you can see where it's been, and nothing else.

It's built for the Saturday morning when you leave at six because the car park is full by eight. For the downtime in the paddock between two sessions, when the stand at the entrance still hasn't opened. For the road trip in the weekend car, when you don't want to stop at every services just because someone's thirsty.

Who it's not for: anyone who drives to the lake twice a year and needs ice for two days. That calls for a hard box you can sit on too. For everyone else, the Daytrip is the bag for the day when the car is the real reason you're out there at all. Eleven colours to choose from, from Black and Charcoal to Torch Orange, all side by side in the YETI category.

The one line no manufacturer puts on the packaging: a cool bag doesn't die from the fabric, it dies from being shut. Close it damp in the evening and put it in the boot, and in three weeks you'll have a smell you can't get out. Wipe it out, leave it open, only stow it the next day. Two minutes of effort, and the thing lasts ten years.

How long does food stay cold in the YETI Daytrip?

YETI deliberately gives no hours figure. In a hands-on test, salad and yoghurt were still cool after almost five hours in the car, without any ice pack at all. With an ICE Sheet it's more. It won't last a whole weekend — that's what the Hopper Flip 12 is for.

Is the Daytrip cool bag leakproof?

The inner liner is leakproof, the MagSnap closure isn't. So a tipped-over drink stays in the liner, but upside down in a backpack won't work. It's not designed to be submerged. That's why YETI recommends flat ICE Sheets instead of loose ice.

Which ice pack fits inside?

One medium YETI ICE Sheet or one to two small ones — that's what the manufacturer specifies for this format. The sheets lie flat on the bottom and take up barely any space. Loose ice melts and pools at the bottom, which you don't want in a bag.

Daytrip 6 litre bag or 5 litre box — which fits better?

The bag stands upright, the box lies flat. For food, the bag, because salad stays in its container and bottles stand. For drinks, the box, which takes ten cans instead of nine and slides under the boot floor.

How do I clean the cool bag?

Warm water with washing-up liquid, wipe out the inside, rinse with clean water. Then leave it open until it's completely dry. Not in the washing machine, not in the dryer, no bleach. Stowed damp, it'll smell within three weeks.

Does the Daytrip fit in the office fridge?

Often not. At 26.2 centimetres tall, it's too high for many fridge shelves — the most common criticism in tests. Measure first. In the car, that exact height is the advantage, because it stands upright in the footwell.

The evening before: Ice pack in the freezer, bag ready to go.

In the morning: ICE Sheet flat on the bottom, cold food straight from the fridge on top, pack it full, press the magnetic strip shut.

On the road: put it down in the shade, open it rarely.

Afterwards: wipe out with warm water and washing-up liquid, leave it open until it's really dry, only then stow it away. Not in the washing machine, not in the dryer, no bleach.
