It holds up to 80 cans, offering ample beverage capacity for small groups.
Why selected: The combination of full insulation and swing-up handles supports easy transport from dock to deck, while the 52-quart size balances capacity with portability. The design minimizes water leakage and helps keep items organized during motion.

Why selected: The sizeable capacity accommodates drinks and food for several people, while built-in cup holders with a molded lid help prevent spills. The design is intended for rougher handling during transport to and from the boat.
Caution: The larger size may be cumbersome for single-handed setup. Ensure it is on a stable surface when unloading to avoid tipping.

Why selected: The 5-layer insulation design with seamless ultrasonic welding helps keep drinks cold for 24 hours, while the bag’s portability suits kayaks and small craft where hard coolers are impractical.
Caution: This is a soft cooler, so it’s more susceptible to squishing or punctures if not handled carefully. Avoid heavy items that could compromise structure.
Buying Guide
- Ice retention vs. capacity: Choose a model that matches trip length and group size. Longer trips benefit larger capacities and multi-day ice retention.
- Portability: If you’ll carry the cooler across docks or stairs, prioritize lighter weight or wheels and ergonomic handles.
- Sealing and closure: Saltwater environments demand durable latches and seals to prevent leaks during boating movement.
- Mounting and stability: Look for tie-down points, non-slip bottoms, and lids that won’t slam shut with motion.
- Materials and insulation: Fully insulated lids and bodies improve ice retention and overall durability on splash-prone decks.
- Maintenance and cleaning: Insulation materials should resist mildew and be easy to wipe clean after spills.
