Learn exactly what fits inside the BrüMate MagPack 18-Can Soft Cooler and get step-by-step packing tips to maximize space and keep drinks ice cold.
Quick answer
The BrüMate MagPack 18-Can Soft Cooler fits 18 standard cans plus ice, or a mix of cans, bottles, and food. Use IceShield™ technology and smart layering to keep everything cold for hours.
Capacity trade-offs: cans vs. mixed loads
While the MagPack 18-Can is designed to hold 18 standard 12-ounce cans, you can swap some cans for a wine bottle, a few tallboys, or snacks. Each substitution reduces can capacity. For example, one 750ml wine bottle takes the space of about 3 cans. Plan your load before packing to avoid surprises.
The soft-sided design gives a little flexibility, but overstuffing can compromise the leakproof seal. Stick to the recommended volume for best performance.
Ice retention and IceShield™ technology
The MagPack uses BrüMate's IceShield™ insulation to keep contents cold longer than standard soft coolers. However, how you pack affects ice life. Pre-chill the cooler, use ice packs or crushed ice, and fill empty space to reduce air circulation. The leakproof lining also prevents melted ice from leaking out, so you can use loose ice confidently.
How to pack the MagPack 18-Can Cooler
- Pre-chill the cooler: Place the empty cooler in the fridge or freezer for 30 minutes before packing. A cold interior reduces thermal shock and keeps ice from melting too fast.
- Layer ice at the bottom: Add a 1-2 inch layer of ice packs or crushed ice on the bottom. This creates a cold base that chills drinks from below.
- Arrange drinks vertically: Stand cans or bottles upright to maximize space and keep them evenly cold. If using cans, place them in rows; for mixed loads, put heavier items at the bottom. Upright arrangement also prevents cans from rolling and breaking the ice layer.
- Fill gaps with ice: Pour crushed ice or small ice packs into any gaps between drinks. This eliminates air pockets that warm the interior. Less air means colder drinks for longer.
- Top with a cold pack: Place a thin ice pack or frozen gel pack on top before closing. This seals the cold from above, especially important if you're opening the cooler multiple times.
- Close and secure the lid: Make sure the zipper is fully closed and the magnetic flap is flat. The leakproof seal only works when the lid is properly shut. Check the zipper track for any fabric caught in the teeth.
