Mochila vs. morral
While both mochila and morral can be translated as backpack or bag, they are not always interchangeable. Mochila is the general, widespread term, while morral often refers to a specific type of bag, distinguished by its material, style, and how it's carried.
Mochila
A1Mochila is the most common and universal Spanish word for a backpack. It typically refers to a bag of any size with two shoulder straps, designed to be carried on the back. It is used for school, hiking, travel, or everyday purposes.

(The children prepared their backpack for the first day of school.)

Morral
B1Morral typically describes a simpler, often rustic bag, frequently made of cloth, woven material, or leather. It is commonly carried over one shoulder or across the body with a single strap, similar to a satchel or messenger bag. Its use is more regional and is particularly common in countries like Mexico and Colombia.

Summary
In summary, use mochila as the default word for any bag carried on the back with two straps, such as a modern school or hiking backpack. Use morral for a more specific type of bag, often with a single strap and a more rustic or artisanal feel, like a satchel or a haversack. While almost any two-strapped backpack is a mochila, not every mochila can be called a morral, and the distinction often depends on style and region.
