A soft sided insulated cooler bag has a base and side panels. The base includes a rigid or semi-rigid reinforcement or batten that serve to provide a relatively hard or stiff edge about which the bag can be panel folded over on itself. The upper edge of the bag has a length that is as great as half the periphery of the bottom panel. The bag can be collapsed to a flat position and then panel folded to a storage position. Retainers are provided to keep the bag in the storage position. The bag has lifting apparatus, which may be strap. The straps may be anchored to the bag at a plurality of anchor points, some of which may be sliding keepers, such that the handle can be moved to a first position in which the bag may be held in a predominantly up-and-down orientation, and to a second position in which the bag may be held in a predominantly flat or horizontal position.

The foldable insulated bag of claim 1 wherein: said first sidewall panel has at least a first margin; said closure member running along at least a portion of said wall structure adjacent to that first margin; said strap handle is restrained at first and second retention points on said sidewall panel distant from said first margin, and at third and fourth retention points on said sidewall panel more proximate to said first margin than are said first and second retention points; said strap handle includes a flexible member running from said first retention point to said third retention point, from said third retention point to said fourth retention point, and from said fourth retention point to said second retention point; in said first position said strap handle has a bight located between said third and fourth retention points, said bight being of size to extend beyond said first margin; and in said second position said strap handle has a bight located between at least one of (a) said first retention point and said third retention point; and (b) said second retention point and said fourth retention point. 8. The foldable insulated bag of claim 7 wherein said third and fourth retention points are keepers and said strap handle is at least partially slidable with respect thereto. 9. The foldable insulated bag of claim 1 wherein said bag is a double fold bag. 10. The foldable insulated bag of claim 1 wherein said forming panel has a flexural rigidity greater than any other portion of said bag, said forming panel including a pair of spaced apart, parallel, stiffened straight edges. 11. The foldable insulated bag of claim 1 wherein said insulated wall structure includes a base panel and a sidewall structure mounted about said base panel, said forming panel being said base panel. 12.
