💬 Reviewers Have Said

  • "It’s a great bag, very durable and strong...I find the pockets to be perfect, even the narrow side pockets have many uses. Even without wax, I’ve found the bag to rain repellent."
  • "The inside is fairly roomy, I can fit my 16 inches MacBook Pro with a case on it perfectly and still have enough room for more items. The overall design of this bag is really awesome, I love the leather trim so much because it just gives it a more solid feel. I had to toy a bit with the adjustable straps to get them right, but once I did the bag fit perfectly! I would genuinely recommend this bag to anyone looking for a reliable sturdy backpack that’s going to last many many years to come!"
  • "This pack uses the G1000 HD which can take a lot of abuse. I also appreciate the simplicity of the top load as there are few zippers to break and you can overload this pack."
  • "This stylish bag has the look of a traditional rucksack with nice leather accents but also has the functionality of modern needs. At first I thought the side pockets were too small for any water bottles, but once I looked inside, I found a larger-sized pocket for my Nalgene to fit! You'll also find two sleeves for a laptop (maybe 15" at most) and another sleeve for my iPad. I use the side pockets for an umbrella and my sunglasses. Overall this bag seems to pack a punch for its simplistic look."

Fjallraven Rucksack No.21 Review (2 months)

"For two months now I have been carrying the medium Fjallraven Rucksack No.21 as my daily commuter bag. It is a svelte little bag that looks great and manages my stuff pretty well. It’s low profile makes it fantastic for navigating busy streets and buses. Style and comfort wise it’s fantastic..."

Fjallraven Rucksack No. 21 Review

"The Rucksack No. 21 may have a throwback look, yet it accommodates modern day needs. For starters, the Fjallraven Rucksack No. 21 has a padded laptop sleeve incorporated into the back panel. There is also an included bottle pocket to help keep a thermos or water bottle upright. This pocket can hold a traditional bike water bottle, Camelback water bottles, Stanley coffee mugs/thermos/water bottle, yet a standard Nalgene bottle is a tight fit. I have also used the bottle pocket to place my charge cords for my computer, phone, and tablet."
