Sealock manufactures the Waterproof Fishing Sling Bag with Airtight Zipper for Lure Fishing, model SL-E548, for anglers who need tackle sealed dry and reachable in one movement. As a welded waterproof-bag factory, we close the main compartment with a genuine airtight waterproof zipper — the sealed type used on dry gear, not a coated coil zip — so this waterproof sling bag holds an IPX7 rating and keeps lures, reels, a phone and documents dry through rain, spray and a slip into the water. Moulded attachment plates on the side take a rod holder or tools, and the single padded strap swings the bag to the front so you can work your tackle without putting it down.
At a Glance
Genuine airtight waterproof zipper — IPX7 sealing, not a coated coil zip.
Sling carry, swings to the front — reach your tackle without taking it off.
Moulded side attachment plates — mount a rod holder, pliers or tools.
Ventilated mesh back — keeps your back cooler on the bank.
Slim 22 × 9 × 42 cm — light, low-profile, stays out of your cast.
Airtight Waterproof Zipper, IPX7
The main compartment closes with a genuine airtight waterproof zipper that runs the full curve of the body, and the welded shell has no exposed stitching for water to work through. Rated IPX7, the bag is built to keep the inside dry even if it goes under during a wade or a slip on wet rocks — real protection for reels, electronics and a phone, not just rain resistance. We verify the seal on every unit with a full water-immersion test, submerging the closed bag for more than two hours and confirming the inside stays dry.
Sling Carry Built for Casting
A single wide, padded shoulder strap with a cross stabilizer strap and quick-release buckle holds the bag firmly against your back while you walk the bank — then swings it around to your chest in one motion when you need to change a lure. The slim 9 cm profile keeps it clear of your casting arm, and the ventilated mesh back panel and padded strap keep the load comfortable through a long session in the sun.
Rod and Tool Attachment System
Moulded attachment plates welded onto the side panel give you fixed, reinforced mounting points for a rod holder, a pliers sheath, a landing net or a lanyard — so your tools ride where you can reach them, not loose in the bag. A front moulded loop and a top grab handle add more clip-on and lifting points.
Front Waterproof Zip Pocket
A long vertical waterproof zip pocket on the front holds the small things you reach for constantly — a phone, licence, keys or a spare spool — separate from the main compartment, so you are not opening the whole bag in the rain.

Supported
|
Our OEM/ODM capability goes well beyond colour and logo changes: bring a sketch, a sample or a target spec — capacity, IPX rating, fabric, zipper type, strap configuration and tackle layout — and our China base develops it from the ground up into a finished original product. Ground-up development needs longer lead time than a stock-colour change, so share your launch date and we will schedule sampling.
