Peak DesignTravel Line Backpack 30L (Sage)

I have been looking for a bag that I thought was a unicorn. A bag that I could take for carryon items, had easy access, fit under an airline seat and be a reasonable daypack when on travel for camera equipment. I tried various backpacks and some fit what I wanted, but not everything. Usually, the biggest issue was the bags had too many pockets and compartments. Then I found this. Put simply, it just worked. I took a trip to Italy recently and it worked exactly how I needed. On the plane, I had extra clothes, various electronics, passport wallet, water and snacks and it fit under the seat, including on a regional jet in Italy that tend to be smaller than ones in the U.S. (I also carry a LowePro bag for all of my camera gear). I could carry it as a regular bag, on top of my luggage or as a backpack. The fold away straps worked great and helped passing through security. During the trip, I used it to carry camera gear that I needed during the day as well as a rain jacket, snacks and water. I use padded camera gear insets to hold lenses and such and the large panel opening was great in getting access that I needed. It was also handy to put my camera in the bag when I went in restaurants or places that didn't allow photography. The bag is pricey, but I'm very happy I made the investment. It was well worth it.

I did a lot of research before buying this backpack. I wanted a clamshell style that would fit certain airline (Spirit) requirements. This is extremely well made very comfortable. You can carry it with handles on different sides and the backpack straps can be put away for storage under your airline seat. It has some internal small zipper compartments as well as a small compartment at the top which is perfect for your phone sunglasses wallet etc. You will not be disappointed with the quality and practicality of this travel backpack. I use it with compression bags and it works perfectly.

Giving four stars still because it’s high quality and a nice bag. For me however, I am not a fan of the one large pocket opening directly near the back piece and arm straps. If your bag is backed heavy and you start unzipping, the weight will literally open the rest of your bag and contents will fall out. Only way to do it safely is to lay the bag down flat on the outside, and then open the clamshell to get to everything. And again, if your bag is packed full, you cannot get to the small zippered pockets in the inside without opening the whole bag and going through everything to get there. So just realize the oraganational pockets in main compartment are inaccessible during the day without opening entire bag

This has been a fantastic backpack for traveling light. I can easily pack for 3-4 days (clothing and toiletries) plus bring two laptops alone for the ride. Could I use some more space at times? Sure, but I love the one bag lifestyle. The suitcase-like opening of the main compartment is great, too. After 6 months, the bag has held up well with no signs of wear.

I recently purchased this bag for an oversea travel, as a carry-on bag travel. Although this is a great Peak Design bag, I ran into too many shortcomings during my trip.PRO: 1. Material of the bag.2. The bag is deep and is able to incorporate 2 medium size and 2 small size Peak Design compression cubes.3. The ability to stow away is backpack straps was key to my purchase decision.CON: A. Harness strap is a bust. Too difficult to put on and off. never end up using. Just needed a solid click on buckle would be better. Sometime reinventing the wheel is not necessary for a try and true system.B. No Hip Belt. The Hip Belt is an optional purchase on the smaller 30 Liter. Although I just didn't feel I needed it, given it was comfortable enough for me to bear the load of just clothing.c. The luggage pass through required me to turn 90 degrees side ways to mount through my carryon luggage handle. This presented several huge problems. First, the weight distribution with my peak design backpack, made my suitcase wobbles when pulling. Second, when i am on the plane, side way mounted bag would not fit easily in the aisle, which meant I had to carry it or wear it. Third, being sideway, made getting my laptop and travel fold out a pain. Forcing me to remove from the luggage pass through and flipping it upright. It is a small gesture, but when you are at airport security, it is not an efficient motion to quickly moves thing along.D. The external inverted flap, not exactly sure why, it is a good usable space, but as inverted, it became useless.E. Lack of tech compartment on the small bag, meant I had to carry my phone in my pocket along with my passport and boarding pass.F. The water bottle compartments are worthless when the back pack is fully loaded. I think that are should have expandable mesh material to compensate.Conclusion: Don't know about the big brother, but the small bro bag is a good bag, just not for travel for me. The bag had too many shortcomings that made traveling through the airport and plane a hassle. Unfortunately I will need to explore other options.

I have been reading reviews and watching youtube in search for a one-bag travel backpack. This is among the top 3 in most reviews, and it is indeed amazing. Traveling a couple times with it, good for up to 10 days trip in tropical climates; Fits all cheap flights carry-on requirements; sleek design, great functionality

Very nice construction with stretchy pockets
