Choosing the right life jacket (or Personal Flotation Device) is one of the most important decisions you’ll make before hitting the water. In New Zealand, the “best” jacket isn’t just about safety standards—it’s about which one you are actually willing to wear all day.

Here is a breakdown to help you decide between a Traditional Foam jacket and a Modern Inflatable model.

1. Traditional Foam Life Jackets

Often called “inherent buoyancy” vests, these are the classic choice. They use closed-cell foam to keep you afloat the moment you hit the water.

• Best For: High-impact water sports (jetskiing, biscuiting, water skiing), children under 15, and non-swimmers.
• Pros: * Instant Buoyancy: No activation required; they work even if you are unconscious.
  • Durability: Can handle rough treatment, sun exposure, and salt with minimal wear.
  • Low Maintenance: Just rinse with fresh water and dry. No gas canisters to replace.
  • Impact Protection: The foam acts as a “body armor” buffer if you fall at high speeds.
• Cons: Can be bulky, warm in the summer, and may restrict your range of motion for activities like casting or rowing.

2. Inflatable Life Jackets

These jackets are slim and lightweight, using a CO2 canister to inflate a bladder when triggered. They come in Manual (you pull a cord) or Automatic (inflates upon immersion) versions.

• Best For: General boating, fishing from a boat, and yachting where comfort and mobility are priorities.
• Pros: * High Comfort: Extremely low profile; most boaties “forget they’re even wearing it.”
  • Superior Buoyancy: Often provide 150N–275N of lift, which is significantly more than standard foam vests.
  • Safety Positioning: Designed to turn an unconscious wearer face-up in the water.
• Cons: * High Maintenance: Requires an annual self-check or professional service. You must check the CO2 cylinder for corrosion and expiry dates.
  • One-Time Use: Once inflated, you must “re-arm” it with a new canister and bobbin before using it again.
  • Not for High Impact: Not recommended for jetskiing or white-water sports as the force of hitting the water can cause accidental inflation or damage the bladder.

The Golden Rule

Regardless of the type you choose, a life jacket only works if you’re wearing it. For children or those not confident in the water, foam is the safest bet. For active boaties who find foam too restrictive, a well-maintained inflatable is the best way to ensure you stay protected all day long.
