Thule 21L or 23L Departer Daypack
- Choose between a 23L model and a 21L model which we’re selling at the same price to protest the metric system.
- The 21L model can hold a 15" laptop; the 23L can hold a 13" laptop. Both have a space for a 10.1" tablet.
- Apparently the 21L is made in the USA, whereas the 23L is imported. From where? We don’t know! Perhaps they were harvested in the lush rolling pack-fields of Tuscany!
- 23L has one water bottle pocket; 21L has two.
- Model numbers: 3202906 and 3202903 (or “3202903+3” and “just 3202903” as we call them at the math festival).
Shopping is Hard
We want things to be simple. We want there to be a single metric that answers definitively: should I buy this thing, or should I buy this other thing? Hence each industry’s placement of one core statistic on the proverbial pillar. Thread count, megapixels, screen size, etc. Everything starts with a number.
But these numbers don’t tell the full story. Not when you’re buying sheets, or cameras, or televisions. And definitely not when you’re buying a backpack.
Case-in-point: these two Thule Departer backpacks. One has 23 liters’ worth of space, the other has 21. But unless you’re looking for a bag to inconspicuously sneak as much soup as possible into the movie theater, the liter count is far from the only number need. For example, through some Tardis-like distribution of interior space, the 23L Departer is actually a more compact backpack. Somehow, though, its two additional liters cannot be parlayed into more space for your computer, as the 23L can hold only a 13" laptop, whereas the 21L can hold a 15"laptop. Yet even this is debatable. According to the Amazon Q&A, though, it’s less a matter of your laptop’s screen size; rather, it might be an issue of thickness.
Point is: one number isn’t going to give you everything you need to know. So you have two options. 1) You can pore over all the numbers, consult charts, attend panel, question experts, etc.; or 2) you can buy whatever bag looks cooler.
We recommend option 2.
