An empty bag in the suitcase, ice from the hotel machine when you want it.
Gel packs are the usual cold step at home, but they need a freezer – and many hotel rooms do not have one. An ice bag turns that around: it travels empty and is filled where the ice is. Mueller’s is a 9 in (22.8 cm) blue fabric bag with a TPU liner and a white screw-top lid. The listing says to fill it two-thirds with ice, close the lid, and afterward drain it and let it air-dry. The maker says the fabric wicks moisture and turns darker as it does.
There is no strap, so the bag is held in place by a hand, a towel or simply by lying still, and at 9 in it covers one knee or ankle at a time. The listing gives no usable figure for weight or capacity.
Tip: Leave the lid off until the bag is completely dry before you pack it – and check that the lid is screwed on straight before you lie down on hotel bedding.
