If you want undiluted ice-cold milk for lunch, these will do exactly that, assuming you pour the milk into an insulated bottle. These type of bottles, without the ice pack, will result in slightly warm tasting milk by lunchtime. These ice packs were designed to be the optimal size for a 0.6 L drink to be kept ice-cold for lunchtime in the bottle. These bottles are a partner in your hiking and can keep the water cold for 3 to 4 hours.
Instructions for best results: Put Ice Pack in freezer overnight. Place Ice Pack into insulated water bottle. Fill bottle with cold drinks from the fridge. They work similar to ice, since that is exactly what they are.
