This kept our milk & eggs cold for a week of tent camping! More importantly, it kept my kids’ meds cold!! We just refilled ice every few days. We keep it in the back of the van or SUV, boat, & anywhere else we travel! It kept our meals, medicines, & drinks cold while we traveled around national parks too. The best cooler we have ever had! Yeti collets really are worth it! LTKfamily LTKtravel LTKSeasonal
