YETI Daytrip 3L Insulated Lunch Box Black, One Size

What Our Gearhead(R) Experts Are Saying:"I use the 3L Lunch Box for short workdays and trail snacks because it's compact but still keeps food cold until evening. The structure is more rigid than a soft lunch bag, so nothing gets crushed, and it fits easily in most daypacks. Adding a medium Ice Sheet really extends the chill time."We pack the Daytrip 3L Insulated Lunch Box when we only need a small, reliable cooler to keep food fresh through the day. Its compact form slides neatly into totes, commuter packs, and travel bags, giving us a sturdy place to stash fruit, sandwiches, and quick trail fuel. The insulation holds steady for hours, especially when paired with a medium Ice Sheet, so we can leave early and stay out longer without worrying about temperature-sensitive snacks. Built with the same attention to durability found across YETI coolers, the structured design keeps food protected from bumps and shifts in our pack. Whether we're driving between trailheads, working outside, or heading to the beach, the Daytrip 3L makes it easy to bring along the essentials.
