This bag is alright. I own two of the 45L bags and i just love them. I was just looking for something a little smaller for shorter trips. Comfort is normal, nothing too exciting. Nice looking bag. BUT, left out the side access and the better design features of the 45L. Traveling with this bag not so great, when you have to access something mid-flight or on the street. For the price i would have expected all the great design ideas of the 45L. I would recommend you just spend the extra cash and go with the 45L for better on the go accessibility. In the end i just went back to using the 45L and gave the 30L to my friend.
Before the TB30L was created by PD I had bought the 45 Liter big brother of it. Because there was no other backpack with all the hug advantages this superb backpack offers to a photograph, musician, traveller or commuter. It's so practical like no other backpack I've known before. BUT: At some occasions it is just too big. So, here comes it's little brother to save the situation: The 30 liter travel backpack! For daily use it's just perfect sized and it offers all the practicability I am used from his big brother in every condition. Superbly done, Peak Design. I can just recommend it!
This backpack is very unique and comfortable when you carry this backpack for a long time. Also the expandable feature is so useful especially when you travel somewhere and buy souvenir and other stuff. You can definitely enjoy this backpack!
