This denim child’s vest has up to 3lbs of weights in 4oz and 2oz increments that may be placed in the bottom back and front in the 8 slots with Velcro. Weighs may also be placed in the shoulder- 2 at each shoulder (4 slots) The entire vest slips over the head and closes at the sides with Velcro adding further customization and grow with the child. This vest is near new. My son only used it a few times. It was custom made by a local seamstress. The denim makes it look less like a therapeutic weighted vest and a bit more natural. In perfect condition.
