I have been looking for a small, portable, 100% leakproof cooler for use when I travel for business to keep drinks cold all day and after many (and I mean, MANY) purchases of other soft side coolers that failed (i.e. leaked), I found ICEMULE! I love this cooler. It packs down into a small form for travel and holds several drinks (bottles, cans, etc) and keeps them ice cold all day. I am very happy.
