Most soft coolers collapse the moment you set them down, which makes them awkward to pack and worse to clean. This one is built around a rigid-box frame, so it stands upright on its own, keeps a square internal shape, and presents a large top opening you can reach straight into. For a charter deck, a campsite or a truck bed, a cooler that stands and stays open is simply faster to load, unload and rinse out — and it stacks and stores better than a floppy bag.
The insulation here is a serious 50 mm high-density XPE layer — thicker than a typical soft cooler — wrapped inside a 600D TPU laminated waterproof shell. That thickness is the reason it holds ice and chilled drinks below temperature for more than 48 hours in normal outdoor conditions. Combined with the airtight zipper sealing the large opening, it gives the kind of cold-hold buyers expect from a rigid cooler, in a 2.1 kg pack you carry on your back.
The body of 22L IPX7 Waterproof Insulated Cooler Backpack with Airtight Zipper is high-frequency welded into a seamless waterproof shell with no needle holes, the opening is closed by an airtight waterproof zipper that keeps out rain and spray, and the base is a reinforced TPU bottom that takes the wet ground and abrasion a cooler sits in. Together they give the IPX7 waterproof rating. Inside, the food-grade TPU airtight membrane is leakproof and easy to wipe clean, so melt-water and food stay contained. We verify every unit's seal in-house with a full water-immersion test, submerging the closed cooler for more than two hours and checking that the interior stays dry.
A separate front waterproof pocket gives you a protected place for accessories you want to keep dry and reach fast — kept clear of the main cold compartment so warm air does not get cycled into your ice.
Because it carries a dense, fully-loaded 22L, the harness is a complete one: padded shoulder straps, a sternum strap and a waist belt that transfers weight onto the hips. That is what makes a heavy cooler walkable over distance — the load sits on your frame, not just your shoulders. The reinforced backpack system is built for the repeated heavy use of fishing, hunting and overlanding.

A high-end wearable cooler for serious outdoor days:
Each 22L IPX7 Waterproof Insulated Cooler Backpack with Airtight Zipper starts with cut 600D TPU laminated fabric, the 50 mm XPE insulation layer and a reinforced TPU base. We high-frequency weld the main compartment and food-grade liner into a seamless build, install the airtight waterproof zipper, and assemble the rigid-box structure, the full harness and the front waterproof 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, run an ice-retention check against the 48-hour target, and pull-test the straps, sternum strap and waist belt. The zipper seal, the welded liner and the reinforced base are the points we inspect hardest.
Sealock builds the SL-I280 for OEM and ODM cooler brands from an MOQ of 300 pcs, FOB Guangdong, with samples in 7–15 days and production in 30–45 days. Standard colour is black, with gray, blue, khaki, orange and custom colours available. Beyond colour and logo, we offer full ground-up custom development: bring a sketch, a sample or a target spec and our China base develops the cooler from scratch — structure, pattern, insulation thickness, materials and hardware built to your order as an original product. Ground-up development needs extra lead time, so share your launch date and we will schedule sampling.
