If you're in the market for a carry on backpack, two strong contenders are the Cotopaxi Allpa 35L and the Aer Capsule Pack Max (40L). Both offer substantial carrying capacity and organizational elements that frequent travelers will appreciate.

The Allpa 35L by Cotopaxi offers a well-balanced combination of durability, convenience, and airline compatibility. Made of 1680D ballistic nylon paneling, this robust backpack lives up to the harsh challenges of frequent traveling. It's light, weighing just 1.5 pounds, yet offers a sizeable 35 liter capacity. The internal organization is impressive and the backpack comes with a number of extras, including a rain cover and collapsible laundry bag. More than that, the Allpa 35L enjoys wide compatibility, fitting the carry-on size requirements of 80% of airlines.

On the other end, the Aer Capsule Pack Max (40L) is slightly larger and comes with its own unique features. Though it offers 5 liters more in capacity, it's a zero-weight bag due to its 1680D Cordura® ballistic nylon exterior. However, it may not fit as many airlines' size requirements, showing compatibility with just 47%. The organization options are ample and the comfort of wear stands out, making it perfect for long-term travel. What's more, the Capsule Pack Max promises durability, a trademark of Aer products.
