100% Airtight & Fully Submersible
Every seam is sealed using high-frequency heat welding - no stitching, no needle holes, no leak points. Combined with a premium #10 airtight zipper, this backpack achieves true IP67 protection. Drop it in a river, get caught in a downpour, or take it snorkeling - your gear stays completely dry.

Floats When Dropped
The airtight construction creates natural buoyancy. If the bag falls overboard during kayaking, rafting, or sailing, it floats safely on the surface instead of sinking - protecting valuables and giving users time to retrieve it.

Tactical Front Panel - Velcro Patch + MOLLE Webbing
The newly upgraded front panel features a large Velcro field for name tags, morale patches, or branded labels, plus integrated webbing loops for attaching tools, carabiners, water bottles, or accessories. Perfect for team identification, branding, or expedition customization.

13" Laptop Sleeve + Organized Interior
The main compartment is wrapped in a waterproof inner lining and includes a padded sleeve for laptops or tablets up to 13", plus dual elastic mesh pockets for cables, power banks, headphones, and small accessories. Business-ready, adventure-tough.

EVA-Molded Back Panel + Dual D-Rings
The contoured EVA back panel and shoulder straps deliver ergonomic support, breathability, and cushioning for long-haul comfort. Two side D-rings expand carry capacity for carabiners, flashlights, or tool pouches.

Heavy-Duty TPU Construction
The thickened TPU-coated tarpaulin resists abrasion, tearing, UV exposure, and aging - built to survive years of harsh outdoor use without cracking or peeling.

Water Sports: The airtight waterproof expedition backpack is suitable for kayaking, paddle boarding, boating, rafting, sailing, fishing, swimming trips, and beach activities. The floating design helps protect gear if the bag accidentally falls into water.

Outdoor Adventure: For hiking, camping, cycling, climbing, trekking, and fishing, the waterproof structure helps protect clothing, electronics, documents, and personal items from rain, mud, and wet ground conditions.

Daily Commuting: The 13-inch laptop compartment makes this bag useful for rainy commuting, cycling to work, school use, and short-distance travel. It protects laptops, phones, files, and chargers from sudden rain.

Travel and Short Trips: The 20L size works well as a lightweight travel backpack for weekend trips, airport carry-on use, and dry/wet separation during outdoor travel.

Professional Field Work: This backpack is also suitable for inspection teams, rescue workers, water-related operations, outdoor construction, surveying, field maintenance, and other wet-environment jobs where equipment protection matters.

We can produce both traditional sewn bags with premium fabrics and fashion-oriented designs, as well as non-sewing waterproof bags made with TPU materials, waterproof zippers, and welded construction.

For welded products, if we already have the required mold and stock materials, the delivery time can be as fast as 5 days. For OEM/ODM projects, lead time depends on customization details, sample approval, order quantity, and material availability.

Flexible production capacity allows us to support small custom batches as well as bulk OEM orders.

Q1: What is the minimum order quantity (MOQ)?
We offer flexible MOQs to accommodate both startups and established brands. Small-batch custom runs and large-scale OEM orders are both welcome. Contact us with your project details for a tailored quote.

Q2: How long is the production lead time?
For orders using our existing molds and in-stock materials, lead time is as fast as 5 days. Fully custom orders typically take 25–35 days depending on complexity, customization, and order volume.

Q3: Is this backpack truly 100% waterproof?
Yes. Unlike "water-resistant" or "splash-proof" bags, our backpack is fully airtight and submersible to IP67 standards - tested to withstand 1-meter submersion for 30 minutes with zero water ingress.

Q4: Can it really float on water?
Yes. The airtight sealed construction creates natural buoyancy, so the bag floats on the surface if dropped into water - protecting contents from sinking or being lost.

Q5: What customization options are available?
We offer full customization including color, logo (heat transfer, silk screen, embroidery, woven label, embossing), size, capacity, fabric, accessories, and packaging. Send us your specs and we'll bring them to life.

Q6: What logo printing methods do you offer?
We support silk screen printing, heat transfer, embroidery, woven labels, and high-frequency embossing. The best method depends on your design and order volume - we'll recommend the optimal option during the quote process.

Q7: Do you provide samples before bulk production?
Yes. We provide pre-production samples for your approval before initiating bulk manufacturing. Sample lead times and fees vary by customization level.

Q8: Are your materials environmentally compliant?
Absolutely. All materials meet RoHS and REACH international standards, making our products fully export-compliant for EU, US, and other global markets.

Q9: What payment terms do you accept?
We accept T/T (bank transfer), L/C, PayPal, and Western Union. Standard terms are 30% deposit with the balance paid before shipment. Custom terms can be discussed for long-term partners.

Q10: Can you ship worldwide?
Yes. We ship globally via sea freight, air freight, and express courier (DHL, FedEx, UPS). We'll recommend the most cost-effective option based on your destination and timeline.
