I love this bag. It is simple, but with a lot of thought and care put into the design. Also, the sage color is beautiful!
I don't particularly appreciate using carry-on suitcases. They are cumbersome and annoying. With the 30L Travel Backpack and a small duffel bag, I can get up to a week's worth of travel supplies (maybe more if tried). It works perfectly with the packing cubes.
I would make two changes: 1) Increase the size of the outer pocket a little, and 2) put stronger magnets into the external flap. The current outer pocket size works, and I can fit a lot of stuff in there, but just a little more room would be nice. The outer flap is OK to hold the external carry straps, but the magnets don't feel strong enough for me to trust keeping a sweatshirt or light jacket stashed in there.
Overall, a great backpack!

Used this for travel for work
The bag is very rugged
Also quite waterproof
Was in France and it was pouring
But arriving hotel
Inside Was dry
Also very very good zippers
Laptop compartment is great as well as the possibility to hide the back straps

Hard to tell how it will hold up but so far the backpack seems good quality. I wish the front quick access pocket was deeper and the luggage pass was horizontal not vertical

I recently purchased the Peak Design Travel Backpack 30L, and it has exceeded all my expectations. This backpack is perfect for short trips and daily use, thanks to its expandable capacity from 27L to 33L. The weatherproof 100% recycled nylon canvas ensures durability and protection for my belongings. I love the large rear hatch that makes accessing my items effortless. The padded laptop and tablet sleeves offer excellent protection, and the expandable side pockets are incredibly convenient. The tuck-away shoulder straps are a thoughtful touch, making it versatile for different carrying styles. Plus, the compatibility with Peak Design Packing and Camera Cubes is a game-changer for organizing my gear. Knowing it's Fair Trade Certified and 100% carbon neutral makes me feel good about my purchase. This backpack comes with a lifetime guarantee, solidifying it as the best backpack I've ever owned. Highly recommended!

I bought this 3 weeks ago in person at the San Francisco store. It was my first time in San Francisco and I wore it all over town packed with lots of gear for more than 3 days. It’s very comfortable and feels very sturdy. I love the external carry straps, which I used to carry my winter coat and a thick hoodie since the inside was very full including my laptop. I actually like it they there are only two zippers, since I put a lock on both for worry free travel on public transit and crowded areas. Would definitely recommend.

Traded my 45L for the 30L and I am happy about it. I am on the shorter side and the 30L looks more proportional on me. What I like about it is that the placement of the top shoulder straps are above my shoulders, not dragging below my shoulders, and more balance on me. Now I don't look like a kid with an oversized backpack.
