(Updated January 2026)
The Fjällräven No. 21 Backpack (often listed as Rucksack No. 21) is now a legacy style. It’s no longer part of the current line-up, but it remains well regarded for its robust build, thoughtful layout and classic Scandinavian look. If you’ve been searching for it as a Father’s Day gift or a daily pack, this guide explains what made it popular and where to look for comparable designs in the current range.
The smaller No. 21 Mini built its own following as a practical choice for younger adventurers, travel days and the school run. Inspired by Fjällräven’s backpack heritage from the 1960s and 1970s, it delivered the same core idea in a compact, easy-to-carry format.

What made the No. 21 a standout
No. 21 earned its reputation by getting the basics right: hard-wearing fabric, sensible pocketing, and a carry feel that suited everyday use just as well as a weekend away. It even cropped up in mainstream fashion coverage, which helped keep the model on people’s radar long after its release.
- Hard-wearing fabric: G-1000 HeavyDuty Eco (recycled polyester and organic cotton) for abrasion resistance and dependable structure.
- Leather details: full-grain leather on the lid straps and trim added strength and a clean finish.
- Functional organisation: a top-loading main compartment with snow-lock, lid pockets for smaller items, and an internal sleeve with a dedicated bottle pocket.
- Seat pad included: a removable foam pad tucked inside the back sleeve, handy for breaks and extra comfort.
- Tunable weather resistance: performance could be increased with Greenland Wax on higher-exposure panels.

The No. 21 Mini: why it became a family favourite
The No. 21 Mini earned a reputation as a durable, stylish and practical choice for younger adventurers, travel days and even the school run. Crafted from robust waxed G-1000 HeavyDuty fabric with natural-toned leather detailing, it balanced a vintage look with dependable performance.
During testing on a family trek, the bag handled wind and light rain with ease. Treated with wax, it shed moisture effectively – keeping its contents, from sandwiches to spare layers, dry and ready for use. The interior was thoughtfully designed, with a separate sleeve for a tablet or small laptop, a pocket to keep a flask upright, and enough room for lunch, notebooks and travel essentials.
Additional features such as a removable sitting pad, a secure zipped pocket for valuables, and padded leather straps with an adjustable chest strap made it comfortable even on longer days out. It was part of a wider family of vintage-inspired packs, offered in multiple colours including Red, Ochre, Navy, Black, Green and Lake Blue.

Availability update
The Fjällräven Rucksack No. 21 Mini has now been discontinued. While it is no longer available new, similar durability, style and practicality can be found in the current range, including the Kånken series and variations and the High Coast backpack range.
Materials and waxing: G-1000 in plain terms
Across No. 21 and No. 21 Mini, the defining feature was the fabric. G-1000 HeavyDuty (and the Eco version) gives structure, resists scuffs, and ages in a way many people prefer to lighter synthetics. A light application of wax can improve beading and wind resistance on the lid, sides and base while keeping ventilation reasonable on the back panel.
If you’re new to it, the simplest approach is:
- Wax the high-wear zones first (base, lower sides, lid).
- Keep it light on areas that sit tight to the back if you want more breathability.
- Build in thin layers rather than one heavy coat.
Useful references if you want more detail: our guide to G-1000 fabric, plus the original Greenland Wax used across the range.
Leather straps and sturdy hardware were also key to the feel of these packs. They were chosen with longevity in mind, and they helped the bag keep its shape when loaded.
What to look for in a replacement
If you’re replacing a No. 21 (or the Mini), it helps to decide which parts mattered most to you. In practice, most people are trying to match a small set of traits:
- Access style: top-loading with a lid and snow-lock, or a zipped opening for quicker access.
- Organisation: device sleeve, upright bottle pocket/holder, plus a secure pocket for valuables.
- Carry comfort: padded straps, stable fit, and a back panel that stays comfortable on longer days.
- Fabric feel: G-1000 builds a structured “rucksack” shape; lighter fabrics pack down more easily for travel.
If your main use is commuting or school, a zipped daypack with a proper sleeve can be a better match than a pure top-loader. If your use is short walks and weekends away, a lid-and-snow-lock style often feels closer to the original No. 21 experience.
Current Fjällräven alternatives that match the same idea
While No. 21 is no longer in production, there are strong options in the current catalogue that keep the same balance of durability, function and everyday practicality.
- Greenland Top: heritage lines with a lid and snow-lock, close in feel to No. 21 for everyday carry and shorter walks. See the current Fjällräven rucksack line-up.
- Raven series (20/28/30): zipped daypacks with clean styling, padded device sleeves and practical pocketing for commuting. Browse Fjällräven daypacks with laptop storage.
- High Coast Foldsack / Foldsack No. 1: lighter, fold-top access with a neat profile that works well for travel and regular use. Explore the High Coast range and fold-top styles.
- Kånken No. 2 (and related Kånken options): a familiar silhouette with leather trim and hard-wearing fabric, often chosen as a simpler alternative to the No. 21 Mini. View Kånken bags and backpacks.
Accessories and organisers
If you valued the No. 21’s internal order, small add-ons can help recreate that setup in a newer pack. Have a look at Fjällräven accessories and organisers for sleeves, pouches and pack-friendly extras.
If you’re hunting a legacy No. 21: quick buying notes
Because these packs are discontinued, condition matters more than the label. A few quick checks can save frustration:
- Check the leather straps for cracking where they bend and where they meet the buckles.
- Look at stress points (base corners, strap anchor areas, zip pulls and stitching).
- If it has been heavily waxed, make sure the fabric still folds and moves cleanly where the lid closes.
- Confirm the internal sleeve and bottle/holder layout still fits how you carry your kit now.
In many cases, a current pack from the wider Fjällräven backpack collection will give you the same day-to-day usability, with simpler replacements if straps or hardware ever need attention.
Whether you owned one for years or you’ve only just discovered it, No. 21 and No. 21 Mini remain good examples of what Fjällräven does well: structured fabrics, sensible storage, and designs that cope with real use.
