I picked one of these up while picking up a set of the luggage straps this morning. Nice size, very well made too.
* Robust shell & base, zip opening and carry handles
* Holds up to six 1.5L bottles horizontally or ten 1L bottles upright
* 2 elasticated straps for securing food or drinks
* Capacity (L): 25
* Extra opening in the lid makes removing individual items of food or drink easy
