The ideal cool bag for longer sessions. Fully insulated with high-density foam and reflective liner and with a removable, easy-clean liner. A molded, waterproof, EVA base and ultra-hard- wearing, PU-backed, waterproof material and high-spec clips and straps, as used on mountaineering equipment, ensure that the SP Session Cool Bag is built to last and to perform to the highest standard. This is the big brother to the smaller SP Cool Bag.
