Being hot is miserable! That’s why we made COLDIES Neck Collar & Bra Inserts: to deliver cooling relief when you need it most. But COLDIES aren’t traditional ice packs. They don’t require pre-freezing, don’t feel painfully icy against skin & don’t leave behind drips or a melty mess. Instead of relying on frozen water, COLDIES use innovative Phase Change Material. It absorbs body heat to deliver a steady, gentle cooling effect that lasts up to 30 minutes. When it wears off, there are two ways to reset COLDIES: let them rest at room temperature for about 60 minutes, or pop them in the freezer for 10 minutes. In hot or humid conditions, the freezer is always the most reliable option. Once reset, they’re ready to use again… and again and again. Available in two styles so you can choose your cool: COLDIES Bra Inserts tuck under the boob, held in place by the bra itself (no adhesive), & feature a half moon design that fits all shapes. COLDIES Neck Collar rests comfortably around the neck, is lightweight & easy for anyone to wear. Get COLDIES & be ready the next time a heat-mergency strikes!
