When choosing a Fjällräven backpack, two models often come into focus: the Foldsack No. 1 and the Vidda Pro. Both are built with the brand's signature durability and Scandinavian design, but they cater to different environments. The Foldsack No. 1 is a heritage-inspired city pack, while the Vidda Pro is a rugged outdoor companion. This article breaks down their differences in materials, capacity, comfort, and intended use, helping you decide which one fits your daily life.

Design Philosophy and Intended Use

The Foldsack No. 1 is rooted in Fjällräven's classic 1970s backpack design, updated for modern urban use. It features a simple roll-top closure, a front pocket with a leather strap, and minimal external organization. It's meant for commuting, school, or casual city trips where style matters as much as function. In contrast, the Vidda Pro is built for the trail. It's part of the Vidda series, designed for hiking, camping, and outdoor work. It has a more technical layout with multiple compartments, side pockets, and attachment points for gear. The Vidda Pro is also available in a larger version (35L) for extended trips.

Materials and Durability

Both backpacks use Fjällräven's G-1000 HeavyDuty fabric, a blend of 65% polyester and 35% cotton. This material is waxed for water resistance and can be re-waxed to maintain its protective coating. However, the Vidda Pro uses a thicker, more robust variant of G-1000 HeavyDuty (HeavyDuty Eco) that feels stiffer and more abrasion-resistant. The Foldsack uses a slightly lighter version, making it more pliable for everyday carry. The Vidda Pro also has reinforced seams and a more robust zipper system, whereas the Foldsack relies on a leather strap and buckle closure. The leather details on the Foldsack add a vintage touch but require more care.

Capacity and Organization

The Foldsack No. 1 has a capacity of 16 litres, suitable for a tablet, a light jacket, lunch, and a few books. It has one main compartment with a roll-top closure and a small front pocket. There's no laptop sleeve, but a padded sleeve can be added separately. The Vidda Pro comes in 20L and 35L versions. The 20L is comparable to the Foldsack but offers more organisation: a padded laptop sleeve (fits 15-inch), a front compartment with zippered mesh pockets, two side pockets for water bottles, and a top pocket. The 35L adds a sleeping bag compartment and compression straps. If you carry a laptop daily, the Vidda Pro 20L is more practical.

Comfort and Carry System

The Foldsack has simple padded shoulder straps and a top handle. There's no hip belt or sternum strap, so it's best for light loads. The back panel is lightly padded but not ventilated, which can lead to sweat in warm weather. The Vidda Pro, especially the 35L, features a more advanced carry system: contoured shoulder straps, a sternum strap, and a removable hip belt. The back panel is also padded and includes a frame sheet for load distribution. The 20L version has a simpler design but still includes a sternum strap. For heavy loads or long walks, the Vidda Pro is far more comfortable.

Urban vs Outdoor: Practical Considerations

In an urban setting, the Foldsack's slim profile and classic look fit seamlessly into cafes, offices, and public transport. Its roll-top allows easy access, though packing can be a hassle if you need to retrieve items at the bottom. The Vidda Pro's more technical look might feel out of place in a business casual environment, but its organisation makes it a better work bag. For outdoor use, the Foldsack lacks essential features like water bottle pockets and a hip belt. The Vidda Pro excels on hikes: you can stow trekking poles, carry a hydration bladder (the 35L has a sleeve), and secure bulky items with compression straps.

Price and Value

As of 2025, the Foldsack No. 1 retails for around £90 / €100 / $120. The Vidda Pro 20L is about £120 / €140 / $160, and the 35L around £150 / €170 / $200. Prices vary by retailer like Fjällräven, Amazon, and outdoor specialty shops. The Foldsack is cheaper but offers less functionality. The Vidda Pro costs more but lasts longer for outdoor use. Consider what you'll use it for: if you rarely hike, the Foldsack saves money; if you need a versatile bag for both city and trail, the Vidda Pro 20L is a better investment.

Which One Should You Choose?

To help you decide, here's a quick comparison:

  • Choose the Foldsack No. 1 if: You want a stylish, minimalist urban backpack for light daily carry. You don't need a laptop sleeve or water bottle pockets. You prefer a classic, vintage look.
  • Choose the Vidda Pro 20L if: You need a laptop sleeve and better organisation for work/school. You occasionally hike and want a bag that works both in town and on trails. You value a sternum strap and more durable fabric.
  • Choose the Vidda Pro 35L if: You're an outdoor enthusiast who needs a larger pack for day hikes or overnight trips. You want a hip belt and sleeping bag compartment.
