We are examining the Cotopaxi Allpa 35L and the STM Good Myth Backpack 28L. Both backpacks are well-reviewed and have many features to consider, but they do have some key differences.

The Cotopaxi Allpa 35L is a sturdy, sensible option for travel. It clocks in at a full 35 litres capacity, made possible by the bag's generous dimensions, 20 inches tall, 30 wide, and 51 deep. Made of 1680D ballistic nylon paneling, the Allpa offers a rugged toughness. It features a laptop compartment for a 15-inch device, useful for those who need tech on the go. While it is compatible with 80% of airlines, you might encounter occasional issues with fitting it in overhead compartments. Still, the Cotopaxi Allpa's durability, volume, and sensible design make it a popular choice amongst seasoned travellers.

Differently, the STM Good Myth Backpack 28L is a more compact option. 46 inches tall, 31 inches wide, and 18 inches deep, it is a little smaller than the Allpa but it makes up for its compact size with lightness, weighing only 1.2 pounds. It is crafted from 100% polyester, durable yet offering a different feel than the Allpa's nylon. Another notable difference is its laptop compartment, designed to house a 16-inch device. Its compact size is reflected on the compatibility with airline carry-on compliance; the STM Good Myth for, in fact, is suitable for 99% of airlines, eliminating the occasional issue you might experience with the Allpa.

Main differences summarised:

Both backpacks have their advantages. If you travel with more goods or you want a bag with higher durability, the Cotopaxi Allpa 35L, with its sturdy make and added capacity, is a solid choice. However, if you value lightness, slightly higher laptop capacity, and smoother airline experience, the STM Good Myth Backpack 28L may be the better fit. Ultimately, your choice should align with your travel needs and preferences.
