Most coolers retain ice just fine, but it’s the backyard barbecue, a day at the beach, camping, fishing and whatever else that comes up in the Dutch backcountry when ice retention becomes really important... If you are serious about keeping your beverages as cold as possible you need a Yeti. A cooler that they describe as “indestructible with superior ice retention”.
Yeti makes a lot more than just coolers. Check out their products.
