How does it work?

• Frozen water-based cooling packs fit into insulated pockets in vests and accessories.
• Non-toxic and chemical-free Kool Max cooling packs are made of biodegradable materials.
• Provide constant cooling for up to 3-4 hours. (Please note: cooling times are estimates and will vary depending on climate, body metabolism and activity.)
• Packs are reusable and should last for years with proper care and storage.
• To use, place the packs in the freezer until they are frozen solid. For best results, store in the freezer, so they're ready when you are!
