Independent buying guides
For commuters and travelers choosing between a backpack, a tote and a slim wallet. Every guide answers a single buying question, prices the choice per year of use, and cites figures with the date checked.
The decisions that actually change what you end up with.
Measurements, sizing systems and how to check before ordering.
What things are made of, and how long that lasts.
What the total comes to once everything is counted.
Each guide answers one buying question and shows the figures behind the answer.
How to choose
Choose a daily bag from the load you carry: how many liters the contents need, which carry style suits the weight, and what the label must say.

Budget and prices
Divide by wears, not by years. The arithmetic that shows when a $120 bag beats a $45 one, what a repair is worth, and where resale changes the answer.

Fit and sizing
Fit a pack by torso length rather than height, keep the load under a defined share of body weight, and adjust the straps in the order that actually works.

Each calculator shows its formula, units and assumptions. Nothing is estimated for you in secret.
Price divided by the number of wears you realistically expect, with cleaning and repair added.
cost per wear = (price + cleaning cost per year x years + repairs) / (wears per month x 12 x years)
Compares your own measurement against a product's stated measurement and shows the gap.
difference = product measurement - your measurement; ease = difference / your measurement x 100
What a cross-border order really costs once shipping, duty and tax are added.
landed cost = (item price + shipping) + duty + tax, where duty = item price x duty rate, and tax = (item price + shipping + duty) x tax rate
Every figure in a guide is taken from a named source, with the date it was checked. Where a number is an assumption or an example, it says so in the same sentence.
We do not run paid product tests, we do not publish reader reviews, and we do not claim to have handled every product mentioned. Where a claim needs a lab or a long-term test we do not have, the guide says that plainly.
Photographs are free-licence images from Wikimedia Commons or Openverse, credited to the photographer with the licence named. Charts are drawn from the figures printed in the same guide.
This site earns money from advertising and, where disclosed, from affiliate links. That does not change the order of a comparison or the conclusion of a guide.
Some links on this site can earn us a commission. That does not change which product a guide recommends, and it adds nothing to your price. Advertising is not enabled on this site yet. When it is, ads will be labelled and kept visually separate from the guides.
