A therapy pack system provides a reusable self-adhering therapy pack to skin. The therapy pack may be for example, an ice pack, heat pack or hot and cold pack. A sticky polymer gel is mounted onto a polymer casing of the therapy pack. The polymer gel is re-usable to attach the therapy pack to a user's skin at the site needing therapy. The polymer gel also buffers the skin from heat or freezer burn associated with applying a hot/cold pack to skin for an extended period. A chloride based compound may be added to the polymer gel to prevent the gel from freezing. In some embodiments, a non-woven fabric patch may support the polymer gel adhesive providing an additional layer of protection to the skin while simultaneously allowing the gel to self-adhere the therapy pack to the user.
