Review: Large, comfortable, super cool - Love it. Easily arge enough for a family picnic. Comfortable. Keeps everything cool all day with ice blocks. Wish I'd bought it years ago.
Review: A practical, well-designed, robust, roomy cooler. - I'm a huge fan of backpacks generally, but never come across a back-pack cooler before. It's a brilliant idea that leaves your hands free with no stretched and aching arms. I genuinely love it and know that living near the beach, it's going to completely replace the bog-standard chunky cooler we normally drag with us for a day out. The quality of this product was very good. It's robust, well-insulated and has loads of room to keep your food fresh, whether you are heading out for a picnic, down the beach, off on a bike ride or just need to keep stuff cool when travelling. With plenty of pockets, front, top and sides, there's room to stash all the extras too, from plates and cutlery to your phone and keys. I love that it also has a handy bottle opener attached, so you can't lose it (which I usually do) and it's ready when you need it. Overall a lovely, practical, well thought out cooler. Genuinely impressed. #gifted
