What is a Clamshell Backpack?
Most backpacks are designed as top-loading with the main compartment entry at the top of the bag. Think of this design as a big bucket that requires you to stack things on top of each other. Although a top-loading backpack has it's advantages, sometimes it becomes a hassle to unpack everything just to reach something at the bottom of your bag.
Enter a clamshell backpack, also known as a panel loader backpack. These backpacks feature a main compartment zipper opening that spans 3 of the 4 sides of the backpack. This allows you to the lay the backpack flat for a birds-eye view of your packing.
Backpacks with a clamshell opening have been popular with photography bags for years. This design allows photographers to quickly access their lenses and gear. But travel and urban backpacks are finally catching up with the trend and adding full clamshell openings to their design. These backpacks allow you to breeze through airport security, quickly access small items at the bottom of the bag and pack the way you want to without compromise.

3-Way Entry
A clamshell backpack has one notable feature that is special to its backpack design: 3-way entry.
Depending on how you position the zippers, you can enter the main compartment in three different ways. Firstly, you can access the main compartment from the top, just like a regular top-loading backpack. This method allows for quick and easy access to essential items without fully opening the bag.
Secondly, a clamshell backpack enables access to the main compartment from either the right side or the left side, making it easy to reach specific items without disturbing the entire pack's contents. Lastly, for those moments when you want full access to all your packing, you can open the zipper fully. This 3-way entry applies if whether it's a front loading backpack or a backpack with a back zipper.

Optimize Your packing
A clamshell backpack, with its convenient "Tetris packing" feature, proves to be a game-changer for travel enthusiasts and everyday users alike.
When you open a clamshell backpack, all of the interior is exposed, allowing you to take advantage of every inch of space efficiently. Using packing cubes or other organizers, you can neatly arrange your belongings within the front-loading main compartment, optimizing the backpack's design for easy access and better weight distribution. Much like a travel backpack that opens like a suitcase, this backpack design ensure you can pack more while keeping everything organized and easily accessible during your travels or daily commutes.

More (Secure) Pockets
One underrated feature of a clamshell design is easy access to inside pockets. This is especially useful for urban travel and carry-on backpacks going through airport security. Many backpack brands have been including more pockets on the inside of their bags for better organization. A panel loader backpack gives you better access to these pockets since all sides of the main compartment are exposed. This means less reliance on external pockets and better security for small items. If you are looking for a backpack with lots of pockets, then a clamshell design may be your best bet.

This makes for an easier time when storing the bag in overhead compartments on planes, trains and buses. The compression straps allow you to adjust the Sojourn Porter's size as needed and the ability to attach a smaller Osprey Daylite or Daylite Plus backpack to the front of the bag for extra storage.

Unlike most front loading backpacks, the Peak Design Travel Backpack features a back zipper for more secure carry. But that's not all! The bag also gives you access to the main compartment through the left and right side as well. Still not impressed?

How We Chose These Backpacks
-
The main driver for adding a backpack to our list was making sure it was a high-quality backpack, especially for those with an on-the-go travel style and urban travel needs. Investing in a backpack made from durable materials like ballistic nylon, X-Pac fabric, or cotton canvas ensures that it can withstand the rigors of frequent use. A well-crafted clamshell backpack will not only last longer but also provide the necessary protection for your belongings during your adventures, giving you peace of mind wherever you go. Whether you're navigating bustling streets or exploring nature's wonders, having a high-quality backpack ensures you can efficiently pack, access your items, and trust in its reliability for many journeys to come.

Having high-quality zippers on a clamshell backpack is crucial due to its unique panel loader design. Unlike traditional top-loading backpacks, clamshell backpacks exert more pressure on the zippers when the bag is packed full. More zippers = more chances of a zipper blow out.
To ensure durability and reliability, we found it essential to recommend clamshell bags from brands we know use quality zippers and stand by their construction. Because of this, you might notice that many of the brands we featured include a lifetime warranty. With high-quality zippers, you can confidently use packing cubes and organize loose items inside the backpack, knowing that the zippers will hold up, allowing for easy access and secure closure during your travels and daily adventures.

At Backpackies, we take backpack design pretty seriously. This is why we put so much emphasis on making sure a backpack has exactly the pockets and compartments you need for daily use and travel. We focused on backpacks that include the essentials plus a little extra.
Whether you're commuting to work or embarking on an adventure, having designated spaces for your belongings can make all the difference. A well-designed backpack is not complete without a laptop compartment to keep your tech safe and accessible. Additionally, compression straps come in handy for compressing the backpack when it's not fully packed, reducing bulk and keeping everything in place. For those who need to carry extra shoes, a dedicated shoe compartment keeps them separate from your other items. Pockets with fleece lining offer protection for delicate items like sunglasses or electronics, preventing scratches and damage. Well-organized compartments allow you to have a designated spot for credit cards, pens, and other essentials, ensuring quick access when needed. Lastly, a water bottle pocket keeps your drink within reach. These are just some of the design features we look for.

At Backpackies, our primary focus in curating the list of the best clamshell backpacks is ensuring they provide ultimate comfort for both daily use and travel. Comfort is a top priority, and we carefully select backpacks that come equipped with features like sternum straps, padded shoulder straps, and hip belts. These components play a crucial role in distributing the weight of the backpack evenly across the body, reducing strain and ensuring a comfortable carrying experience even during extended wear. Whether you're commuting to work or embarking on a large backpacking adventure, having the right support and weight distribution is essential to prevent discomfort and fatigue.
