- Durability: Look for impact-resistant materials like polycarbonate and rugged construction for boat or kayak use.
- Portability: Carrying handles, wrist straps, or belt clips assist in off-water handling.
- Visibility and access: Clear lids or lid designs that allow quick access are beneficial on the water.
