How does a travel bag stay truly waterproof?
The difference lies in material, seams and closure. High-quality tarpaulin or coated polyester/nylon (PU or TPU) forms a waterproof barrier that doesn’t absorb moisture. Welded or taped seams prevent leaks at vulnerable points. The closure does the rest: a roll-top creates a mechanical seal when you roll the top 3–4 times and fasten it. Waterproof zippers have a coated zipper tape with a sealing lip—ideal when you want quick access without rolling. Our ByMetz 3-in-1 travel bag uses robust 900D tarpaulin, while Samsonite Ecodiver works from a durable recycled base with a water-repellent coating. Waterproof means resistant to heavy rain and splashes; prolonged submersion requires a true drybag construction and correct closure. Regular maintenance with suitable impregnation sprays helps retain water repellency.
Choosing the right size and capacity
Pick the litre size for your trip. 30–35L is perfect for a short city trip or as a gym bag. Heading away for a weekend? Our weekend bags are a compact choice. 40–45L often meets carry-on rules and holds 2–4 outfits. 60–70L suits multi-day trips or winter sports, while 90L+ is ideal for expeditions or long holidays. Mind organisation: internal pockets, a wet pocket and a secure laptop compartment make a difference. For commuting, a waterproof backpack with a 15.6" compartment, such as Daniel Ray, is practical.
Waterproof travel bag with wheels
If you travel farther or heavier, wheeled travel bags are ideal. You get a duffel’s capacity with trolley convenience. An example is the Travelite Basics wheeled tarpaulin travel bag—spacious and hard-wearing. Choose wheels if you often roll long distances, travel via airports or want to reduce back strain. Look for a protected base plate, reinforced corners, smooth bearings and a sturdy telescopic handle for comfort and durability. For extra convenience on the go, luggage and travel accessories like locks and straps are useful.
Carry-on and airlines
If you want to bring your waterproof travel bag as carry-on, always check current airline rules. As a rule of thumb many carriers use about 55 x 40 x 20 cm and 8–10 kg. A capacity of 30–45L generally works well. Soft duffels with roll-top are handy because they can be compressed. For an extra compact personal item that fits under the seat, underseaters are ideal. The ByMetz 3-in-1 travel bag is designed to meet the carry-on requirements of most airlines, so you can travel flexibly and avoid extra fees.

Frequently asked questions
Are waterproof backpacks really waterproof?
Yes—provided they are made from coated materials with welded or taped seams and a correct roll-top closure or waterproof zipper. They withstand heavy rain and splashes. Full immersion requires a drybag construction and correct closure.
Can you swim with a drybag?
Short contact with water is fine if you roll the closure 3–4 times and seal it properly. Do not use a drybag as a flotation device, avoid sharp objects and test the closure before departure.
How does a waterproof bag work?
Waterproof bags combine coated or tarpaulin material with welded or taped seams and a waterproof closure. This creates a sealed unit that keeps rain and splashes out, even during heavy use.
What is a good travel bag brand?
If you want durable and light, check Samsonite Ecodiver. For robust wheeled capacity, Travelite Basics is strong. For a multifunctional waterproof solution, the ByMetz 3-in-1 is a smart choice for daily use and travel.
