Ninja FrostVault Go 23 litre 36-can Backpack Soft Cooler

Keeping food and drink properly cold for a full day out is something most cheap soft coolers simply fail at — ice melts fast, zips leak, and you end up with soggy sandwiches by noon. The Ninja FrostVault Go is built around a high-density insulation system and a leak-resistant dry zone that physically separates your food from the ice melt, meaning your lunch stays cold and your phone stays dry even on a long beach day or festival afternoon. At 23 litres with a 36-can capacity, it carries a serious amount of cargo while still being worn comfortably as a backpack — a combination that cheap box coolers and flimsy drawstring rivals can't match.

Who Is This For?

This is aimed squarely at people who spend genuine time outdoors — festival-goers, beach regulars, hikers who want cold drinks at the summit, or parents managing a full day at the park without access to a car boot. If you're the person in the group who always ends up responsible for keeping the food cold, this is built for you. If you only need a cooler twice a year for the odd barbecue, a £30 bag from a supermarket will do the job well enough — you can browse more considered options in our garden and outdoor deals guide or check our Ninja deals tracker for context on the brand's wider range.

What Buyers Say

Owners consistently praise the ice retention, with many reporting drinks still cold after 12-plus hours in warm weather — notably better than mid-market rivals. The padded straps get strong marks for comfort under load. The most recurring grumble is the weight of the bag itself before anything goes in it; the insulation that makes it effective also makes it one of the heavier empty backpacks you'll own.

The Deal

Currently priced at £179.99, down from £229.99, the saving is £50 — a solid 22% reduction. However, this product is newly tracked on our system, so there is no historical price data to confirm whether £229.99 is a genuine long-term price or a pre-discount reference point inflated at launch. That warrants caution. At £179.99 the FrostVault Go is priced at the premium end of soft coolers — justified if cold retention is your priority, questionable if it isn't. Watch for a repeat discount before committing.
