I think this is good for women and children. I think it would be difficult for a large man to fit in with a cast on. Amateur measurements, laid flat: Width at midpoint: 37 cm Height: 21 cm at the highest point Cuff (lowest point): 15 cm Opening: 30 cm Shoulder strap length: ~70 cm Shoulder pad: 20 cm The mesh part is breathable and slightly see-through. I bought this because the hospital's triangular bandage made my neck hurt. It's light and cool, so it's good for supporting splints and casts, or for going out when you're almost healed, just in case. *If you are undergoing treatment, please prioritize your doctor's instructions. In my case, it was okay without a triangular bandage. #ArmHolder #TriangularBandage #Fracture
