In detail: Tourit Sac à dos isotherme 21L
The Tourit 21-liter insulated backpack sets itself apart from classic cooler bags with its back-worn format, in the style of a hiking or travel backpack. This choice frees both hands during the walk, a real advantage when also carrying a parasol, towels or toys on the way to the beach or a picnic spot over a fair distance on foot.
With a 21-liter volume and a stated capacity of up to 30 cans, this insulated backpack targets group rather than individual use: it can carry enough drinks and provisions to feed a family or small group of friends on a summer outing, without having to split the load between several separate containers. The interior insulation, backed by a waterproof heat-sealed lining, effectively holds the cold brought by ice packs, with a retention time stated by the brand of up to 16 hours.
Several pockets round out the main structure: a slim front compartment with an organizer, a discreet pocket for a phone and valuables, and a bottle opener built directly into the straps, a clever detail for a picnic or beach outing. This storage versatility makes it a single bag for a whole day out, without needing extra bags on the side.
The padded, adjustable straps, along with the breathable mesh fabric on the back panel, provide noticeable carrying comfort even when loaded with several kilos of provisions and ice, for a bag that itself weighs 700 grams empty. One point worth flagging honestly: this model's commercial name sometimes mentions 22 liters, while the specifications seen on the sales page state 21 liters, a minor discrepancy but one worth knowing before buying. For families who regularly walk to the beach, a park or a swimming spot far from parking, this backpack format meaningfully improves the comfort of the trip compared with a classic insulated bag carried by hand.

Comparison
In the €20 to 45 range, the Tourit 21L insulated backpack naturally compares to the Quechua cooler backpacks sold at Decathlon, a go-to name in France in this segment. Here is how it stacks up against the ICE 20-liter bag and the 100 series 30-liter cooler backpack, based on specifications published by Decathlon.
| Criterion | Tourit 21L | Quechua ICE Bag 20L | Quechua Cooler 100, 30L |
|---|---|---|---|
| Capacity | 21 L (30 cans) | 20 L | 30 L |
| Cold retention | Up to 16 hours (stated) | 5 hours | 8 to 12 hours with ice pack |
| Weight | 700 g | Not stated | Not stated |
| Extra storage | Bottle opener, media pocket, organizer compartment | Basic | 2 mesh pockets, zipped interior pocket |
| Price observed | €42.99 | ≈ €20 | ≈ €30 to 35 |
In summary, the Quechua bags from Decathlon remain cheaper and suit occasional use close to the car well. The Tourit plays a different card, one of practical details (bottle opener, dedicated pockets, padded back) and a stated cold retention time that is noticeably longer, making it a more versatile choice for anyone who walks to their picnic spot or uses it several times a season.
Our tester's verdict: Yoni Marchal-Laporte
In actual use, this Tourit backpack lives up well to its promise of versatility: worn on the back rather than by hand, it genuinely improves comfort on a somewhat long walk to the beach or a picnic spot far from the parking lot. The bottle opener built into the straps is the kind of clever detail you would not expect at this price, as is the phone pocket that means you do not have to dig it out alongside the drinks. The insulated compartment holds the cold for hours with ice packs, enough for an afternoon, though performance depends on outdoor heat and how full the bag is. One point to flag before buying: the product listing initially mentioned 22 liters, while the specifications seen on the sales page state 21 liters and 700 g empty, a minor discrepancy worth noting. This model still only totals a few dozen reviews on Amazon, a very favorable rating but on a small sample. It remains very good value for occasional family use.
