Buying Guide
What to look for when buying an infant life vest:
- USCG Approval and size range: Confirm the vest is labeled as USCG-approved and designed for infants within 8–30 pounds, with clear weight guidance.
- Fit and adjustment: Look for multiple adjustable straps, a crotch strap, and a headrest if your child is very small. An open-sided design can improve mobility and comfort for younger babies.
- Head and neck protection: A higher collar or headrest can support head stability if the infant’s head lolls backward.
- Ease of use: Consider zipper closures, buckle systems, and grab handles for quick rescue if needed. Easy on/off is important for frequent diaper or clothing changes.
- Material and durability: Choose quick-drying, UV-resistant fabrics that withstand sun exposure and water activities.
- Movement and comfort: The vest should not ride up over the chin or face; ensure a snug, not tight, fit to avoid movement that can compromise flotation.
Frequently Asked Questions
- What weight should a 6-month-old wear in a life vest? If your baby weighs between 8 and 30 pounds, an infant-size PFD designed for that range is appropriate.
