Zoom Washsafe Expandable Cool Bag 5.5L 5 "Zoom Washsafe Expandable Cool Bag. 5.5L" Mrs Flanagan 02 July 2018 This is a really strong,useful cool bag. It could be handy for the office lunch, a picnic in the park or on the beach. I have taken it on a day trip to Wensleydale and it kept things nice and cool for several hours. I like the smart royal blue colour with grey trimming and zips. It expands and is washable, both useful assets of the design. It is suitable for children's packed lunches. I appreciate the fact it has an across the body adjustable strap. Good for hiking. I think the cool bag is very good value for the price, and it will be recommended to family and friends during this hot summer.
