- High quality materials: breathable velvet fabric with an aluminium alloy holder that is easy to shape and carry. The removable soft chest pad adds comfort and is simple to clean. - Suitable for all genders: fully adjustable to fit the whole family and different body types. Helps relieve shoulder, back and neck discomfort associated with sprains, muscle cramps and strains. - Posture corrector design: thoughtfully contoured to provide the right compression for back and waist, helping prevent hunching and supporting a taller, straighter posture. - Practical design: backpack-style construction that does not restrict chest or abdominal breathing, and does not limit shoulder or arm movement. - Use scenarios: use at a desk to improve posture during long work sessions; wear during light activity or walking to reduce fatigue and discomfort; wear after workouts to support alignment and recovery.
