Medline Disposable Instant Cold Packs activate with a simple squeeze to provide immediate cold therapy for sprains, strains, bruises, and post-surgical swelling without the need for a freezer. Each single-use pack maintains therapeutic cold for 20-30 minutes, making them ideal for first aid kits, sports bags, and emergency response kits. The sturdy inner bag design minimizes the risk of leaks, and the textured outer bag provides a comfortable, non-slip grip.
