Product Introduction

Sealock manufactures the SL-C878 Waterproof Travel Duffel Bag with Airtight Zipper for buyers who want real dry-bag protection in a compact, everyday shape. As a welded waterproof-bag factory, we seal the main compartment with a genuine airtight waterproof zipper — not a coated coil zip — and weld the 840D TPU body with no needle holes anywhere in the shell, giving this waterproof duffel bag an IPX7 rating. At 41.5 × 25 × 19 cm and just 0.75 kg, it works as a gym bag, a weekend duffel or a boat bag, with a front waterproof pocket, an internal zip pocket and a reinforced base board that keeps it in shape.

Airtight Zipper, IPX7

The main compartment closes with a genuine airtight waterproof zipper running the length of the top, fitted with a moulded T-grip pull that gives you the leverage an airtight zip needs — so it actually gets sealed properly, even with wet hands. Every seam of the 840D TPU shell is high-frequency welded, so water has no path in through the fabric. Rated IPX7, the bag keeps clothes, electronics and kit dry through rain, spray and temporary immersion. 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.

Front Waterproof Zip Pocket

A welded waterproof zip pocket on the front — with the same moulded T-grip pull — holds a phone, wallet, keys or a pass where you can reach them without opening the main compartment. It keeps the small things sorted and dry, so you are not unsealing the whole bag in the rain.

Interior: Zip Pocket and Reinforced Base Board

Inside, the welded waterproof lining is smooth and seamless so it wipes out dry, and an internal zip pocket keeps documents, a charger or valuables separated from the main load. The bottom carries a reinforced base board — a padded stiffener that stops the bag sagging when loaded, protects whatever sits on the bottom, and lets the duffel stand up on its own instead of collapsing into a heap.

Carry It Two Ways

Twin webbing handles run under the body and pull together for a secure hand carry, and a detachable padded shoulder strap clips to D-rings on the ends when you want it off your hands. Compression straps with quick-release buckles at both ends cinch the bag down when it is part full, anchored on reinforced triangular patches, and a top D-ring gives an extra hanging or clip point.
