Frequently Asked Questions
- What weight range should a baby life vest cover?
Most infant life jackets for babies and toddlers 12-30 pounds are designed to fit children in the 12-30 pound range, with some extending up to 40 pounds depending on the model. - Is USCG approval necessary?
USCG approval adds a standardized safety assurance, but always verify fit and wear during use. - How do I check for a proper fit?
Secure all straps, verify the vest sits above the shoulders, and ensure the child cannot slip out or pull the vest over their face. - What features improve safety for toddlers?
Headrest support, crotch straps, leg straps, grab handles, and three-point buckling systems improve control and keep the vest in place. - Can a life jacket replace supervision?
