Buyer’s Guide: 3 Key Factors to Consider
Visibility & Safety
Your swim buoy is your primary safety beacon. Look for high-visibility colors like fluorescent yellow or orange. Reflective strips and an included safety whistle are major pluses for being seen and heard by boats.
Capacity & Dry Protection
Think about what you need to carry. A 15-20L bag fits keys, phone, and a light jacket. Ensure it’s fully waterproof with a reliable roll-top or double-chamber seal to keep your gear completely dry, even if you rest on it.
Durability & Comfort
The buoy should be made of tough, puncture-resistant nylon or TPU. Check the strap and handles; a wide, comfortable waist strap and a solid rest handle make for a much more pleasant swim, especially on long training sessions.
Frequently Asked Questions
Is a swim buoy really necessary?
Yes, for open water swimming it’s a critical safety tool. It makes you visible to boats, provides a rest platform, and can carry essentials. It’s a non-negotiable piece of gear for responsible swimmers.
Will my phone stay dry in a swim buoy dry bag?
In a quality, properly sealed dry bag, absolutely. Always do a test with a paper towel inside before trusting your electronics. Look for double-chamber designs like the Fetch 50 for extra security.
How much drag does a swim buoy create?
Very little. Modern swim buoys are designed to be hydrodynamic and trail behind you smoothly. You’ll notice the safety and convenience benefits far more than any minor drag.
Can I use any dry bag as a swim buoy?
No. Standard dry bags aren’t designed for buoyancy or visibility. A dedicated swim buoy is filled with air to provide flotation you can rest on and is made in high-visibility colors for safety.
What size swim buoy should I get?
For most swimmers, 15-20 liters is ideal. It offers enough storage without being too bulky. If you need to carry extra layers or more gear, opt for a larger 20L+ model like the New Wave Swim Buoy.
Final Verdict: Which One Should You Buy?
After comparing the top options, the Fetch 50 Swim Buoy Dry Bag stands out as the best overall choice. Its double-chamber design offers unmatched dry storage security, and the included nutrition pouch and whistle add fantastic value. For swimmers who prioritize maximum storage space, the New Wave Swim Buoy (20 Liter) is an excellent large-capacity pick.
