Dry Bag
A dry bag keeps clothes, electronics and food dry on the water, in the rain and in the dust. Ours are roll-top dry sacks made from 500D PVC tarpaulin or TPU-laminated nylon, with high-frequency welded seams and a buckle closure that seals when rolled at least three times. Sizes run from 2-litre pouches for phones and keys to 100-litre boat bags, with options for clear windows, shoulder straps and backpack harnesses. Sealock has made waterproof bags for over 20 years at its own factories in Dongguan, China and Ho Chi Minh City, Vietnam. Every dry bag can be made in your colours and printed with your logo.

How to Choose a Dry Bag

Start with size. 2 to 5 litres holds a phone, keys and wallet; 10 to 20 litres a change of clothes and lunch; 30 to 40 litres clothes and a sleeping bag; 50 litres and more expedition and boat gear. Then choose the material: 500D PVC tarpaulin is tough and cost-effective, TPU-laminated nylon is lighter and stays flexible in the cold. A roll-top is waterproof only when rolled at least three times before buckling. Options include clear windows, shoulder straps, backpack harnesses and purge valves.

Every order passes through incoming material inspection (IQC), in-process checks during welding and sewing (IPQC) and final inspection (OQC), with SGS or QIMA third-party inspection available on request. Our test programme covers seam tensile and bonding strength, load testing of 1,500+ cycles, zipper testing to 3,000 cycles, salt spray on hardware, abrasion, and colour fastness and colour difference against the approved sample. Waterproof ratings are verified on the bag itself: a heavy rain and water-jet test for IPX5 and IPX6 models and a full water-immersion test of 2+ hours for IPX7 and IPX8 models.

Frequently Asked Questions

Do dry bags float?

A sealed dry bag with air inside usually floats, which helps recover gear that goes overboard. It is not a flotation device for people.

What is the MOQ for custom dry bags?

Usually 300 pieces per style; some models start at 200 or 500. Colours can often be split within one order.

How much do custom dry bags cost?

Price depends on the material, size, closure, features, logo method and order quantity. Send us your specification or a reference sample and target quantity, and we will quote.

Can you add our logo and brand colours?

Yes. Screen printing, heat transfer and welded patches are the most common methods, and we can match Pantone colours for the fabric, webbing and zip pulls.

How long do samples and production take?

Samples usually take 7–15 days and bulk production 30–45 days after sample approval, from our factories in China or Vietnam.
