Material: Most models are made from latex-free neoprene fabric, which is stretchy, durable, and designed to generate heat (the "sauna effect") to help with sweating.
Design: These often include spiral steel bones for structure and posture correction, along with a combination of hook-and-eye closures, zippers, and double or triple velcro belts for adjustable compression.
