Anyone who has used a soft cooler knows the routine. Open the lid, grab a drink, zip it back up. Repeat all day. It seems like a small task until you're trying to grab a drink in a moving canoe, jet ski, or off-road vehicle.
That's exactly the problem MagSnap solves. Instead of relying on a zipper every time you reach inside, CORE's magnetic closure system automatically seals the lid the moment you let go. Here is how the technology works and why it changes the way a soft cooler feels to use.
What Is MagSnap?
MagSnap is CORE's magnetic closure system built into every CLIMAKEEP cooler. Integrated magnets along the lid and cooler body pull the seal shut the moment the lid is released. No zipper track to line up, no tab to pull, and no checking whether the seal caught. Drop the lid, and the magnets do the rest.
How Do Magnetic Coolers Work?
The concept is straightforward. Magnets embedded in the lid rim align with magnets in the cooler body. When the surfaces get close enough, the magnetic force pulls the lid into a sealed position.
What makes MagSnap different from a basic magnetic closure:
- Seal strength: Magnets are rated to hold the lid firmly closed even when the cooler is bumped, tilted, or jostled during transport.
- Passive operation: A zipper requires deliberate action. MagSnap closes automatically, which means cold air stays trapped during every quick grab throughout the day, kind of like the door on your fridge.
- Cumulative cold retention: Each automatic seal saves a few seconds of cold air loss. Over dozens of opens and closes, that adds up to noticeably longer ice life.
MagSnap vs. Zippers: Where the Difference Shows
Zippers have been the standard on soft coolers for decades. Our CLIMAKEEP coolers still include a waterproof zipper for sealed transport. But for everyday access at camp, tailgate, or on the beach, the magnetic seal does the job hands-free.
| Feature | MagSnap Magnetic Lid | Standard Zipper |
|---|---|---|
| Hands Needed | One | Two |
| Seal Speed | Instant (automatic) | 3 to 5 seconds (manual) |
| Durability Over Time | No teeth to break or stiffen | Zippers degrade with use |
| Cold Retention When Unzipped | Magnetic seal traps cold | Fully open, cold escapes freely |
| Wet or Cold Hands | No effect on operation | Grip and pull become difficult |
One-handed access matters more than most people expect. At a cookout, one hand holds a plate. On the water, one hand grips the boat. MagSnap removes the need to stop and set things down just to grab a drink.
Where MagSnap Makes the Biggest Difference
The magnetic seal adds value in any setting, but a few scenarios highlight the gap between MagSnap and a traditional closure:
- Tailgates and Cookouts: Frequent access over several hours means the cooler opens and closes dozens of times. Every automatic seal saves a few seconds of cold air loss compared to a lid left unzipped between grabs.
- Beach and Lake Days: Wet, sandy, or sunscreen-covered hands make zipping a cooler frustrating. MagSnap works the same regardless.
- Camping trips: Quick access for drinks, snacks, and meal prep without constantly zipping and unzipping keeps the flow of camp life moving.
- On the Water: Kayaking, boating, and paddleboarding leave one hand occupied. A magnetic lid that seals on release means the cooler stays closed without fumbling.
Which CORE Coolers Feature MagSnap?
MagSnap is standard across the entire CLIMAKEEP lineup. Every size shares the same magnetic closure, HYPERCOLD™ insulation, welded leakproof construction, built-in bottle opener, and exterior pockets.
- 12 Can CLIMAKEEP: Compact for solo day trips and lunch runs. Ice retention up to two days.
- 18 Can CLIMAKEEP: Box-style shape for couples and small groups. Ice retention up to two days.
- 24 Can Backpack: Padded backpack straps for hands-free transport. Ice retention up to three days.
- 36 Can CLIMAKEEP: Full weekend capacity for group outings and all-day cookouts. Ice retention up to three days.
All four are available in multiple colors and feature fully welded seams for leakproof, floatable construction.
MagSnap seals are also featured in our zipperless FlipBack coolers. Pair any size with a camp table, and the cooler becomes the center of the campsite kitchen.
Final Takeaway
MagSnap solves a problem most campers do not realize costs cold retention: the few extra seconds a lid stays open between grabs. A zipper that requires two hands and deliberate effort creates friction. A magnetic seal that closes the instant the lid drops removes that friction entirely.

FAQs
Do MagSnap coolers have a zipper?
Sometimes. CLIMAKEEP coolers include a waterproof zipper for fully sealed transport when desired. FlipBack coolers do not have zippers.
How long do MagSnap coolers hold ice?
The 12- and 18-can CLIMAKEEP models retain ice up to two days. The 24-can backpack and 36-can CLIMAKEEP models hold ice for up to three days. FlipBack coolers hold ice for 24 hours.
Does MagSnap work with wet hands?
Yes. The magnetic seal is not affected at all. Wet, sandy, or cold hands do not change how the lid opens or closes.
Are CLIMAKEEP coolers with MagSnap leakproof?
Yes. Fully welded seams and a waterproof zipper create a sealed interior. The cooler is leakproof when zipped for transport and floatable when fully sealed.
Can MagSnap magnets wear out over time?
Our magnets retain strength for years under normal use. Unlike zippers, magnets have no teeth or moving parts to degrade.
Is MagSnap the same as a regular magnetic closure?
MagSnap is engineered for consistent seal strength across the full lid. Generic magnetic closures often use weaker magnets with gaps along the edges.
