The zipper is the heart of a soft cooler, and this one uses a premium airtight waterproof zipper that prevents water intrusion and locks cold inside.
Compared with an ordinary coil zipper, the airtight seal slows heat exchange across the full opening, which is a major reason this airtight zipper cooler bag reaches 48 hours of ice retention. The large pull tab keeps it smooth to open and close even with cold or wet hands.
A thick 20 mm closed-cell XPE foam layer wraps the main compartment inside the 840D TPU shell. Closed-cell foam does not absorb water and resists compression, so it keeps blocking heat trip after trip. With the airtight zipper sealing the top, this insulated cooler bag holds ice and chilled drinks for up to 48 hours in normal outdoor conditions — enough for a weekend of camping or a full day of fishing.
The body of 24L Waterproof Soft Cooler Tote Bag with Airtight Zipper for Camping and Fishing is high-frequency welded into a seamless build with no stitched leak points, and the inner liner is a food-grade TPU membrane — BPA-free, safe for direct contact with ice, food and drinks, and easy to wipe clean. As a leakproof cooler bag, it holds melt-water inside even when carried at an angle, so nothing drips into a car or onto camping gear. We confirm the seal on every unit with a full water-immersion test, submerging the closed cooler for more than two hours and checking that the inside stays dry.
A front zippered pocket gives you quick, water-resistant storage for the small things you reach for often — keys, a wallet, a phone or accessories — kept separate from the cold compartment so warm air is not cycled into your ice. It is splash- and rain-resistant for everyday outdoor handling.
This is a tote you actually carry loaded, so the carry hardware is built for it: reinforced webbing handles for a quick hand carry, plus an adjustable, detachable shoulder strap that takes the weight off your hands on a longer walk to the spot. Switch between the two depending on the trip.

A soft-sided cooler bag for the everyday outdoor day:
Each 24L Waterproof Soft Cooler Tote Bag with Airtight Zipper for Camping and Fishing starts with cut 840D TPU fabric and the 20 mm closed-cell XPE insulation. We high-frequency weld the main compartment and food-grade liner into a seamless build with no needle holes, install the airtight zipper, and fit the reinforced handles, detachable strap and front zip pocket. Before a batch ships, we run a full water-immersion test — submerging each sealed cooler for more than two hours to confirm it stays dry inside — plus an ice-retention check against the 48-hour target and a pull-test on the handles and strap. The zipper seal and the welded liner are the points we inspect hardest.
Sealock is a soft cooler bag manufacturer building the SL-I230 for wholesale buyers and OEM/ODM cooler brands from an MOQ of 300 pcs, FOB Guangdong, with samples in 7–15 days and production in 30–45 days.
