Versatile travel companion with the Travel 45L Backpack
What Our Gearhead® Experts Are Saying:
"This bag is my go-to for international travel. I love that it starts at 35L for carry-on compliance but expands to 45L when I need extra space for souvenirs. The compression system works flawlessly, and the weatherproof zippers give me confidence when checking the bag. The organization pockets are thoughtfully placed and the Peak Design ecosystem integration is brilliant."
Whether we're embarking on extended journeys or quick overnight escapes, the Peak Design Travel 45L Backpack adapts to our every need. Starting at a carry-on friendly 35L capacity that meets international airline standards, this pack expands to 45L when extra space is essential, while dual expansion zips and compression snaps allow us to scale between 30L and 45L depending on our adventure. Robust face fabric and ultra-light foam padding protect our gear during checked flights, while countless internal and external pockets maintain organization from departure to destination.

Great Backpack
Took this backpack for a week's vacation through Norway. Perfect size fits everything I needed while still being a carry-on size. Perfect for hopping on and off buses and trains through Europe. It was comfortable to wear even while fully packed. The different areas were easily accessible with its numerous zippers.

Superb all-round work/travel backpack
I've owned this backpack for a few years now and absolutely love it! It's my go-to backpack for all things: hiking, traveling, daily commute to/from work, training, etc. The size is great and versatile and I like the wide selection of pockets, and flexibility of the bag + ability to fasten straps to it (2 are included). I like the various compartments and ease of access. One thing that is missing and I would wish for would have been an extractable mini-superlight-backpack or bag, especially where the laptop compartment is. When I travel I often have this as my carry-on bag, but usually want to get my laptop, or iPad, bottle of water and a couple of magazines or books with my to my seat. As there is no extractable "bag", I end up having to extract all these items from various pockets in the bag. Just one simple, yet integrated "bag" to lift out would have been superb.

Perfect, Genius Design.
I didn't know I needed this so badly. We were headed for 2 weeks in Europe and I needed a better option for a carry-on bag. Google search/ratings led me to this bag, that, though it was a higher cost option, had very great reviews. I could not be more thrilled with it. The super quality workmanship put into this and the amount of thought into the design is far better than anything I've had. Pockets are smartly placed, access to the main compartment with side zippers, handles all over the place, and clever stowing of the hip and shoulder straps are just a few of the things that make this such a great product. Throw in a lifetime warrantee and incredibly solid build, and I can confidently say I am a Peak Design fanboy.

A great travel backpack.
A fantastic travel backpack. Perfect for a photo/video camera, personal items, and clothing. It can be taken on board as carry-on luggage, yet it's spacious enough and to fit comfortably on your back. Multiple access points and numerous pockets enhance its features.

Bulletproof and gamechanging
This backpack has been a gamechanger for me when I travel. Often, I find that I can condense what used to be a 2-bag trip to this single backpack. It feels like I can fit way more stuff in here than I have any right to, and the organization is thoughtful and easy to access. In over a year of heavy use, I've had zero issues, even when forced to check the bag on flights. My only complaint is it's a bit on the heavy side, but that's a small price to pay for the durability, features, and organization niceties. Would buy this again in a heartbeat, and it made me a peak design fan for the long haul.

Exceptional design, function and quality
Purchased for a 1-month trip to Europe to complement a medium-sized roller bag. Selection criteria were: 1. sophisticated looks without heavy branding, 2. maximum capacity within European air carrier carry-on dimensions, 3. ease of use atop a roller bag, 4. intelligent and flexible access and partitioning, and 5. quality construction and durability. Simply put, this is an excellent product. It sits securely on top of a roller bag, works well as a backpack when needed, looks sophisticated without drawing attention, is thoughtfully designed, and is well built. My bag shows no signs of wear after daily use for 30 days. The little things: — All grab handles are sturdy and comfortable. — The loop that secures the bag to a roller bag is strong and holds it firmly. — The system that stows and hides the backpack straps when not in use is innovative and works well. — Materials and zippers are excellent, each zipper with a sturdy, elegant pull. — The interior includes loops to secure items, reducing movement and making it harder for someone to slip a hand in and successfully grab valuables. Nicely done.

Best Purchase I’ve Made In A Long Time
I’m in a band that tours heavily doing multi-week runs and 2-4 night runs and this has become my go-to travel bag. It’s really not an exaggeration to say you can pack over a week’s worth of clothing into this bag. All the compartments are well thought out and I can nicely organize tech, meds, clothing, etc. I can’t overstate how much I love this bag.
