Review on 🎒 Black Thule Subterra 30L Backpack by Jeremy Gorsage

I bought the Subterra 23L and 30L to compare because I wasn't sure about the size (see ). I have found that 30L is more beneficial to me on a daily basis. I ride the subway in NYC and need something flexible if needed. The 23L was perfect when I just needed to take my laptop with me, but sometimes need to bring something home from work (or to work with lunch, for example). I also use my backpack when traveling and the larger version fits into weekend wear when the smaller one doesn't. I found the 30L to be much better suited for my daily needs, but you may have others. Both were the same weight (the larger weighed just 0.5 pounds more), but the larger package had two differences that mattered to me: The first was a side zipper to remove the laptop. I found that extremely helpful. The second is a larger second inner compartment. The 23L only has a small compartment and some space in the laptop compartment. 30L has two large compartments.
