Best Bag for Backpacking Europe – 2025 Reviews

When backpacking Europe, carry-on size is non-negotiable unless you want to waste time and money checking bags between flights and trains. Look for backpacks around 40-50 liters with dimensions under 22x14x9 inches—this sweet spot gives you enough space for 2-3 weeks of travel while fitting in overhead compartments.

I’ve found that slightly larger bags might seem tempting, but they often become burdens when you’re navigating crowded metros or stored luggage compartments.

Padded shoulder straps and breathable back panels make all the difference when you’re carrying your life on your back for 10+ hours a day. Look for S-shaped straps that follow your body’s contour and mesh that actually ventilates—your back will thank you during those hot summer days in Mediterranean cities.

Adjustable torso length and hip belts are crucial for proper weight distribution, especially if you’re planning any hiking alongside city exploration.

Multiple compartments transform chaos into order when you’re living out of one bag. I always look for dedicated laptop sleeves, easy-access pockets for passports and tickets, and separate shoe or dirty laundry compartments.

The best backpacks have intuitive organization that lets you find what you need without unpacking everything—a game-changer when you’re rushing to catch a train or need quick access to rain gear.

European weather can be unpredictable, so water-resistant materials are essential. While no backpack is completely waterproof, quality water-resistant fabric with a included rain cover will protect your belongings from sudden showers.

Durable materials like ripstop nylon or polyester withstand the rough handling of travel, while reinforced stitching at stress points ensures your backpack survives countless train rides and hostel floors.

Discreet zippers and lockable compartments give you confidence when navigating crowded tourist areas or leaving your bag in hostel storage. Look for backpacks with hidden pockets for valuables and zippers that can be secured with small travel locks.

I’ve found that anti-theft features like slash-resistant material aren’t always necessary in most European destinations, but discreet design that doesn’t scream ‘tourist’ is always beneficial.

For most travelers, 40-50 liters is the ideal size range for backpacking Europe. This capacity provides enough space for 2-3 weeks of clothing and essentials while remaining carry-on compliant for flights between European cities. Larger bags become cumbersome on public transportation and may require checked baggage fees, while smaller bags might not hold everything you need for longer trips.

While you can use a hiking backpack, travel-specific backpacks are usually better suited for European adventures. Hiking backpacks often have external frames and bulky designs that are awkward on crowded trains and in hostel dorm rooms. Travel backpacks typically feature more discreet styling, better organization for urban needs, and carry-on friendly dimensions that make moving between destinations much smoother.

Water resistance is crucial for European travel since you’ll likely encounter rain regardless of the season or region. While you don’t need a fully waterproof backpack (unless you’re planning extensive outdoor activities), quality water-resistant material with an included rain cover will protect your electronics and clothing from unexpected showers. I’ve found this especially important in cities like London, Amsterdam, and Edinburgh where rain can appear with little warning.

Always prioritize comfort over maximum capacity—you’ll thank yourself after long travel days. A comfortable, properly fitting backpack that’s slightly smaller is far better than a massive bag that causes shoulder and back pain. Remember that you can always pack strategically and do laundry during your trip, but you can’t magically make an uncomfortable backpack feel better after hours of wear.
