Having purchased this recently for a series of music festivals, i was intially sceptical by its claims to maintain coolness for upto 24 hours. The bag has a massive capacity and will easily accomodate a nights worth of food and drink. One word of note is that bags of ice will not suffice as they take far to large an area and will not last as long as freeze blocks. I literally placed 4 freeze blocks inside the bag together with my drinks and was surprised to see they were still chilled 36 hours later. The carry strap enables the bag to be carried easily and when not in use the bag folds away allowing it to be stored neatly without taking up room which a cooler box would otherwise do. I now use this bag for all my camping/day trip activities. All in all, a great product and one I would highly recommend.
36 Litre capacity. The superior temperature retention performance provided by IsoTec is achieved by using a uniquely designed multi-layered insulation structure. It starts with a rugged outer layer of high denier textile that is backed with additional moisture repellent PVC lining. Finally a thick layer of dense, closed-cell polyethylene foam is positioned next to a leak-proof PVC interior lining. The result is the exclusive IsoTec engineered insulation system that keeps contents cold for hours.
