Whether biking to the office, commuting across campus, or heading out on a spontaneous day trip: as soon as dark clouds roll in, having the right gear determines if your laptop, valuables, and spare clothes arrive dry. A waterproof backpack is the ultimate companion – especially during the wet transitional season.
But which model truly fits your needs, how much capacity in liters do you actually need, and what sets weather-resistant fabrics apart from standard everyday materials? We tackle all these questions and more.
Water-Repellent vs. Waterproof: What’s the Difference?
When picking the right backpack, you’ll usually encounter two terms that often get mixed up:
-
Water-repellent: The material features a light coating or a tight weave. Light drizzle or brief showers roll off the surface. However, during heavy, prolonged rain or along the seams, moisture can eventually seep inside. Ideal for short trips and typical autumn days.
-
Waterproof: A completely waterproof backpack stands up to torrential downpours and strong headwind on your bike. Not only are the fabrics entirely impermeable, but the seams are typically welded or taped, and the zippers are specially sealed.
Key Phrase Weather-Proof: The Rolltop Backpack
An absolute favorite for unpredictable weather and rain is the rolltop backpack. The concept is as simple as it is effective:
Instead of (or in addition to) a classic top zipper where water could seep through during heavy rain, the backpack opening is rolled down tightly several times and secured with a buckle or magnetic closure. Rolling it creates a physical barrier that makes it impossible for rainwater to enter.
Added bonus: A rolltop offers highly flexible capacity simply by rolling it up or down.
High-Tech for Everyday Life: Tarpaulin, TPU & Coated Nylon
To ensure your backpack stays moisture-resistant, manufacturers rely on modern, heavy-duty materials:
-
Tarpaulin (Truck Tarp): Extremely rugged, 100% waterproof, and exceptionally easy to wipe clean. Its smooth, subtle matte-sheen finish gives the backpack a striking, urban look.
-
TPU (Thermoplastic Polyurethane): A modern coating that completely seals fabric while remaining flexible and supple. TPU materials feature a particularly sleek, matte, and refined aesthetic.
-
Coated Nylon & Polyester: If you prefer a classic fabric look, opt for tightly woven nylon or canvas with an interior PU coating. This preserves the textile appearance while reliably keeping moisture out.

How to Waterproof Your Backpack: Rain Cover & Waterproofing Spray
Already have a favorite everyday backpack made of leather or fabric and want to upgrade it for rainy days? These two helpers will do the trick:
-
Rain Cover: An elastic, waterproof protective cover that you can quickly pull over your backpack when unexpected rain hits. It folds down ultra-small and takes up virtually no room in your bottom compartment.
-
Waterproofing Spray: Textile and nylon backpacks should be treated regularly with a suitable waterproofing spray. The spray restores the water-beading effect while giving the fabric extra protection against dirt and stains.
How Much Volume Do You Need?
Choosing the right size depends on your daily routine:
-
15 to 20 Liters (Compact & Slim): Perfect for the city, a quick stroll through town, or minimalists who only carry a laptop, charger, and water bottle.
-
20 to 25 Liters (Everyday Standard): The ideal size for university, the office, and quick errands. Offers enough room for a notebook, A4 documents, a lunch box, and a rain jacket.
-
25 to 30 Liters (Maximum Capacity): Ideal for long days, after-work grocery shopping, or as carry-on luggage for weekend trips.
