Whether it's a herniated disc, sciatica, or just years of hard living catching up — your lower back needs real support, not a heating pad and wishful thinking. The Back Brace is constructed with nylon + Spandex Blend, Plastic Support Stays, 100% Latex Free. Dual elastic tension straps and built-in vertical stays lock your core in place while you lift, sit, or push through the day. HSA/FSA eligible through TrueMed. The Pouch Is the Point Most back braces just squeeze. This one has a pouch built into the panel that sits over your lower back, sized for a single Old Bones gel pack. Slide one in and the cold lands exactly where the ache is, from the lumbar spine down through the sacrum, held there by the brace instead of by your hand. Ice It or Heat It The gel packs work both ways. Freezer for ice when something is inflamed and angry. Microwave for heat when you wake up stiff and need to loosen up before you move. Same pack, same pouch, whichever your back is asking for that day. Why Two Packs The pouch holds one. We sell them in twos because a gel pack only stays cold for so long, and the moment it goes lukewarm your icing session is over. Keep the spare in the freezer and you can swap in a fresh one without waiting around. One is on your back, one is getting cold. That is the whole trick.
