Buying Guide: Key Purchase Considerations
- Capacity vs. portability: Larger dry bags offer more storage but can be heavier and less streamlined. Choose based on whether you need to carry extras such as a phone, keys, towel, or spare layers.
- Visibility and safety features: High-visibility colours, reflective panels, and built-in whistles improve safety in open water, especially in coastal or murky conditions.
- Waist belt and attachment options: An adjustable waist belt and multiple carry points (shoulder straps, side straps) increase comfort and versatility, enabling use after the swim as a backpack.
- Dry protection reliability: Look for double-layer designs or sealed inner linings to protect electronics and valuables from water exposure in rough seas.
- Material durability: PVC-coated fabrics balance weight and strength. Check for reinforced seams and a robust inflation valve for longevity in UK weather.
- Intended usage: For triathlons, a compact 15–16 L buoy may suffice, while longer coastal swims may benefit from 28 L capacity with more gear space.
- Maintenance: Rinse with fresh water after use, ensure valves are sealed, and dry completely to prevent mildew and material degradation.
