The SAM Splint from Adventure Medical Kits is an emergency split that makes a perfect addition to any first aid kit. Built from a thin, lightweight core of aluminum alloy and sandwiched between two layers of closed-cell foam. Freshly unrolled from storage, the splint is extremely pliable. Bent into any of three simple curves, it becomes extremely strong and supportive for any fractured or injured limb. Dimensions: 4.25" x 36". Weight: 4 oz.
