Finding the perfect backpack can feel like searching for a needle in a haystack. Piorama has changed the game with their innovative expandable designs that adapt to whatever life throws your way. Whether you’re heading to school, work, or your next adventure, these versatile bags grow and shrink with your needs.
1. Shift Delta – The Ultimate Size Transformer

Picture carrying a compact 16-liter bag that magically expands to hold 42 liters when you need extra space. The Shift Delta makes this possible with its clever roll-top design and multiple access panels.
Built tough with weather-resistant GrainCore nylon and weatherproof YKK zippers, this backpack handles whatever Mother Nature dishes out. The breathable mesh back panel keeps you comfortable during long walks.
Water bottle pockets and padded shoulder straps add practical touches that make daily use a breeze.
2. B3 Adjustable Backpack V3 – Three Bags in One Package

Why buy three different backpacks when one can do it all? The B3 V3 transforms between small, medium, and large sizes, adapting to your changing needs throughout the day.
This latest version boasts IP64 water-resistant construction that keeps your belongings dry in unexpected downpours. Upgraded materials and reinforced design ensure this bag stands up to heavy use.
The optional hip-belt attachment distributes weight evenly during longer trips, while internal accessory points keep everything organized and easily accessible.
3. Adjustable Bag A10 – The Shape-Shifting Champion

Meet the chameleon of travel bags – the A10 morphs through ten different configurations and three capacity levels (31L, 46.5L, 62L). One moment it’s a sleek backpack, the next it transforms into a spacious duffel.
IP64-rated water resistance protects your gear from unexpected storms and spills. Quick-access exterior pockets let you grab essentials without digging through the main compartment.
When adventure calls elsewhere, this bag collapses down for easy storage, making it perfect for minimalist travelers who value versatility.
4. Mega – The Heavy-Duty Hauler

Some adventures require serious cargo capacity, and that’s where the Mega steps up to the plate. This expandable powerhouse handles bigger loads without breaking a sweat.
While details remain somewhat mysterious, early reports suggest this bag follows Piorama’s signature adaptability philosophy on a grander scale. Think of it as the strong silent type of the backpack world.
Perfect for extended trips, camping expeditions, or any situation where you need to haul more gear than usual. Sometimes bigger really is better, especially when space becomes your top priority.
5. Omni – The Pocket-Friendly Performer

Good things come in small packages, and the Omni proves this saying perfectly. This compact adjustable pack delivers Piorama’s innovative design philosophy without emptying your wallet.
Ideal for students, commuters, or anyone who appreciates lightweight carry options, the Omni punches above its weight class. Despite its smaller stature, it maintains the brand’s commitment to quality and functionality.
Sometimes you don’t need all the bells and whistles – just reliable performance at a price that makes sense. The Omni delivers exactly that combination.
