My kids and I bring our Camelbak backpacks (100oz and 70oz), fill the bladder with ice, top off with water and it stays cold all day. My wife refuses to drink from a Camelbak so I will be carrying around her 40oz Hydroflask that will not shrink or get lighter towards the end of the day but it does stay cold......LoL
