Charleston is a city that thrives outdoors. From sunrise fishing trips off Folly Beach to lazy afternoons floating on Shem Creek, locals know how to make the most of Lowcountry living. Coolers are packed almost daily stuffed with subs, snacks, and drinks for boat rides, beach outings, and backyard gatherings. But as any Charlestonian knows, keeping everything fresh and intact isn’t always easy. Sandwiches end up soggy, ice turns to water, and glass bottles don’t always survive the ride.

That’s where Subsafe steps in. Founded with one simple but brilliant invention, the brand has grown into a full lineup of products designed to solve the very problems every cooler owner faces. They aren’t just clever gadgets they’re practical, durable solutions built for the way we live in the Lowcountry.

The Original SubSafe

The product that launched the brand and landed Subsafe a deal on Shark Tank is the Original SubSafe. This crush proof, waterproof container was made to keep sandwiches from being ruined by cooler water or pressure from ice packs. Available in both six inch and footlong sizes, it’s tailor made for a Publix sub (Pub sub), a Harris Teeter hoagie, or your favorite wrap from a local deli.

Charleston boaters quickly adopted it as more than just a sandwich case. It doubles as a waterproof snack holder, a safe place to stash small valuables, or even a cocktail shaker when the party starts at the sandbar. It’s one of those rare products that’s just as practical as it is versatile.

Subsafe 2

The other option, the Subsafe 2, builds on that original design with more versatility. Along with protecting your food, this version works as a reliable dry storage container for essentials like phones, keys, or wallets items no one wants to lose to the saltwater. It’s dishwasher safe, BPA-free, and tough enough to handle everything from offshore fishing trips to family beach days. For Charlestonians who spend more time outside than in, it’s a no brainer. The Subsafe 2 allows for the classic square sandwhich to fit a bit better than the Original Subsafes pub sub shape. 

Charcuterie Safe

Picnics in Charleston are an art form whether it’s a blanket spread at White Point Garden or an evening watching the sunset from Waterfront Park. The Charcuterie Safe makes it possible to enjoy meats, cheeses, fruit, and crackers without worrying about cooler water seeping in and ruining the spread. Imagine uncorking a bottle of wine on Sullivan’s Island and pulling out a perfectly preserved brie, crisp crackers, and fresh strawberries it’s a Lowcountry luxury with a practical twist. Traditional tackle boxes are often made with chemicals to protect soft baits and hooks from rusting. Which means you do not want to use a tackle box as a Charcuterie Safe, buy one from Subsafe that's made with food grade materials.

This product in particular captures the Charleston lifestyle  blending a little elegance with everyday adventure. It turns a casual outing into something special.

Wine Safe

If there’s one Subsafe product that feels tailor made for this city, it’s the Wine Safe. Charleston’s culture revolves around hospitality, good food, and even better drinks but glass bottles, boats and beaches don’t always mix well. The Wine Safe solves the problem with an insulated, protective case that keeps your bottle intact and at the right temperature.

It’s the kind of product that makes it easy to bring a favorite bottle along for a sunset cruise, a sandbar gathering, or a picnic at the Battery without worrying about spills or breakage.

Ice Safe

Ask any Charleston local, melted ice water is the enemy of a cooler. The Ice Safe eliminates this frustration by keeping the ice contained and separate from your food and drinks. Instead of fishing soggy sandwiches or floating snack bags out of the water, everything stays clean and dry. Even better, it extends the life of the ice, keeping items cold for longer.

For a city that spends as much time outdoors as Charleston does, this little innovation makes a huge difference. Beach days, RiverDogs games, and backyard barbecues all benefit from a cooler that actually stays cold without the mess.

10-in-1 Boat Tool

No Charleston adventure would be complete without a boat, and no boat should leave the dock without the 10-in-1 Boat Tool. Compact and sturdy, this multitool covers all the small but essential tasks you’ll run into on the water. From opening bottles and cans to tightening screws, cutting lines, and pulling corks, it saves the day again and again.

On long days offshore, it’s the kind of tool that earns its keep. And for sandbar gatherings or Shem Creek cruises, it’s equally handy for less technical tasks like popping open a round of drinks for the crew.

Built for the Lowcountry Lifestyle

What sets Subsafe apart isn’t just clever design it’s how seamlessly the products fit into life in Charleston. Every item feels designed for people who live outdoors, love the water, and know the value of keeping things simple. A family beach trip, a fishing charter, or a picnic downtown all become easier and more enjoyable with Subsafe in the mix.

Charleston has a unique rhythm, equal parts laid back and refined and Subsafe mirrors that balance. Their products are rugged enough to handle long days on the water but refined enough to make a picnic feel like an occasion.

Final Thoughts

Subsafe started with the humble goal of protecting a sandwich, but today it offers a collection of products that elevate every Lowcountry adventure. The Original SubSafe, Subsafe 2, Charcuterie Safe, Wine Safe, Ice Safe, and 10-in-1 Boat Tool each address everyday frustrations with smart, durable solutions.

What makes them stand out is their usefulness beyond novelty they’re items you’ll find yourself reaching for every time you pack a cooler. In a city where life revolves around the outdoors, they’re quickly becoming essentials.

So the next time you load up for a day on Folly, a sandbar picnic on the Wando, or a tailgate at The Joe, think about packing smarter. With Subsafe on your side, your food, your drinks, and your Charleston adventures are protected.
