In detail: Lifewit Insulated Backpack, rated up to 24L, hiking and beach format
The Lifewit insulated backpack stands apart from classic insulated bags with its two-shoulder backpack format, rather than a hand-carried or single-strap design. This frees up your hands during the walk, a genuine benefit for hiking, the beach, or a picnic spot far from the car park.
At 21 x 28 x 37 cm, this backpack targets group use or an extended outing: the brand rates its capacity at up to 24 litres, with an interior that can hold up to 30 cans or a mix of drinks and food. The precise technical specs state 21 litres, a minor gap but worth knowing before buying.
Insulation relies on a dedicated foam that limits heat exchange with the outside, backed by adjustable straps for comfortable carrying even when loaded. A shoulder strap is also included, to switch between the backpack format and more classic carrying depending on the route and the load.
At just 200 g empty, this bag stays light to carry once folded, without needlessly cluttering a bigger bag or a car boot. It mainly targets outdoor outings, camping, hiking, beach or picnics, rather than everyday office use, for which a more compact insulated bag remains more practical.

Our tester's verdict: Yoni Marchal-Laporte
Used on a half-day hike with a picnic at the end, this Lifewit backpack quickly showed the appeal of the two-shoulder format over a classic hand-carried insulated bag: over several kilometres of walking, the comfort difference is genuinely noticeable, especially loaded with bottles and several meal containers. Despite weighing just 200 g empty, the insulation held up well across the 4 to 5 hours of the outing, with only slight warming noticeable late in the day under direct sun. The included shoulder strap, on top of the backpack straps, is a real plus for anyone who prefers switching carrying modes depending on the route. One thing worth knowing before buying: the product listing sometimes mentions a 24-litre capacity, while the precise technical specs state 21 litres, a minor but real gap. For regular use hiking, at the beach or camping where your hands need to stay free, this format remains a sensible, affordable choice.
