Our best cold packs! Deluxe Cold Packs are a sweat-less, paper covered poly nylon bag, that can be applied directly on the skin and don't require a compress holder. They need no refilling, require no clumsy ties and stay at a lower consistent temperature longer than other cold packs. Self-contained design reduces the risk of cross contamination and eliminate the sterilization, reprocessing and maintenance of reusable packs.
