In order to create a space with cold surrounding air for drinks, put ice packs on the sides of the insulated main compartment. If you're using fresh ice, we would recommend putting the ice in a sealed bag first. ?? Tip: Place a small towel at the bottom of backpack to reduce moisture condensation.

To keep drinks cold in a standard backpack in 2026, you should use a vacuum-insulated stainless steel bottle (like a Yeti or Hydro Flask), which can maintain temperature for 24+ hours regardless of the bag's environment. If you are carrying plastic bottles or cans, place them inside a neoprene sleeve or wrap them in a damp towel and put them in the center of the bag, surrounded by clothes for insulation. For a more "professional" setup, many 2026 backpacks now feature a dedicated insulated "cooler" pocket lined with PEVA material. Another effective "hack" is to freeze a half-full bottle of water the night before and top it up with your drink in the morning; the ice core will act as a "chiller" for several hours. If you are using a hydration bladder (like a CamelBak), you can purchase an insulated hose cover and sleeve to prevent the water in the reservoir and tube from being heated by your body heat or the sun, ensuring every sip remains refreshing even on a long hike.
