Cool Bag - 6 can size with strap

[Ali P]

Does anyone know of a supplier of cool bags? I am after some that are sized to accommodate 6 upright cans (or approx size H14cm x W22cm x L15cm) with printable tops and a shoulder strap. I have checked my usual places but can only find more of a 'lunchbag' style. Failing that, ANY plain non-printable cool bags Thanks in advance
