Why We Chose The Hydro Flask 22L Insulated Soft Cooler Pack: Effective, comfortable to carry, convenient.
Let’s get straight to what you’re here for. You want to know if this actually works, and if so, how well.
Yes. It does work. And as the Outdoors Magic team found out, it does a pretty good job.
Full disclosure: we couldn’t take this out for any hot weather hiking, the reason being that those conditions are quite difficult to find in the UK between February and April. Instead we had to make use of our stuffy office.
“Hydro Flask say that it will keep the contents cold for 48 hours”
We stuck a bunch of warm beers – warm as in room temperature-warm – inside the Hydro Flask Soft Cooler then chucked in a bag of ice and zipped it up tight. After seven hours we had a look inside and there was only a very tiny puddle at the bottom of the pack with the beers delightfully chilled. At 10am the next day we checked inside again and the ice was still there, all in a very drippy state but still looking like ice. By the end of day two, it was one big puddle inside with tiny little bits of ice floating around – the beers, still pleasantly chilled.
Hydro Flask say that it will keep the contents cold for 48 hours. And that’s a pretty valid claim, however, if you’re out in the park with friends and someone keeps reaching inside every 10 minutes the chill time will be vastly reduced. In one of our tests, we left a tiny gap in the zip and the ice melted much faster.
