Product Introduction

Sealock manufactures 40L & 60L Roll-Top Waterproof Duffel Dry Bag for Kayaking, Camping & Travel, model SL-K099, for buyers who need a duffel that keeps gear dry through spray, rain and rough handling. As a roll top waterproof duffel bag factory, we weld the body from TPU waterproof fabric and close it with a three-fold roll top, so this waterproof duffel bag keeps water, dust and sand out whether it is strapped to a kayak deck, a motorcycle rack or thrown in the back of a truck. It comes in two sizes and carries three ways, which is why it works equally well as a travel bag, a gear bag and a wet-kit hauler.

Fully Waterproof Roll-Top Construction

The body is high-frequency welded into a seamless waterproof shell with no stitch holes, and the three-fold roll-top folds down and clips to lock out water. Rated IPX7, this roll top waterproof duffel bag holds out spray, rain and the wet of a kayak or boat deck, while keeping dust and fine sand from working into your gear on a dusty trail. We confirm the seal on every bag with a full water-immersion test, submerging the closed bag for more than two hours and checking that the inside stays dry.

Two Sizes: 40L and 60L

Both sizes share the same welded construction; you choose by load:

40L — a waterproof duffel bag 40L that works as a dry weekender and kayak dry duffel bag for paddling, rafting and travel; easy to carry and quick to pack.
60L — a heavy-duty waterproof gear bag 60L built as a motorcycle waterproof duffel bag and boating hauler, with the volume for a full camp kit, wet gear and bulky equipment.

Heavy-Duty Carry, Three Ways

Reinforced webbing handles support heavy loads for a quick grab or a two-person lift, and an adjustable, detachable shoulder strap turns it into a shoulder-carry duffel for longer walks. Used flat it is a duffel bag, slung it is a shoulder bag, and lashed down it is a gear transport bag — one bag covering the way you actually move kit on a trip.

Front Bungee Gear System

An adjustable front elastic bungee system on the outside holds the things you want fast or want to keep off your dry kit — a rain jacket, a towel or wet gear after a paddle. It keeps the bulky, damp items lashed to the outside while the inside stays sealed and dry.

Reflective Panels and Abrasion-Resistant Base

Reflective side patches lift visibility for night loading, roadside motorcycle stops and low-light activities. Underneath, an extra-reinforced base takes the abrasion of rocks, docks, gravel and rough terrain that wears through the bottom of a bag first — the part that decides how many seasons a heavy-duty waterproof gear bag survives.

How We Make and Test It

Each duffel starts with cut TPU waterproof fabric. We high-frequency weld the body and the reinforced base into a seamless build with no needle holes, fit the roll-top, reinforced handles, detachable strap, front bungee system and reflective panels. Before a batch ships, we run a full water-immersion test — submerging each closed bag for more than two hours to confirm it stays dry inside — and pull-test the handles, strap anchors and base under load. The welded seams and the handle anchors are the two points we inspect hardest, because a duffel is judged on whether it stays dry and survives being thrown around.

OEM / ODM and Wholesale

As the factory, we supply this waterproof duffel bag for OEM, ODM and wholesale buyers from an MOQ of 300 pcs, FOB Guangdong, with samples in 7–15 days and production in 30–45 days. We customize colour and contrast side-panel combinations, add your logo in the printing methods above, and adjust sizing, bungee layout and strap configuration. For a custom or wholesale waterproof duffel bag program under your own brand, send your spec and target quantity and we will quote against it.

FAQ

How waterproof is it?

It is rated IPX7 with a high-frequency welded body and a three-fold roll-top, and we verify each bag with a full water-immersion test of more than two hours. As with any roll-top, the seal depends on rolling the top down fully before closing.

What is the difference between the 40L and 60L?

The 40L is a compact dry weekender for kayaking, travel and day trips; the 60L is a heavy-duty hauler with the volume for motorcycle camping, boating and full gear loads. Both use the same welded waterproof construction.

Can it carry on the shoulder?

Yes. It carries by the reinforced handles or by the adjustable, detachable shoulder strap, and can be lashed down as a gear transport bag.

What are the MOQ and lead times?

MOQ is 300 pcs per size, FOB Guangdong, with samples in 7–15 days and production in 30–45 days. Custom colours and logos are available. Send your spec for a quote.
