Laptop Compartment Fit and Protection
Not all backpacks labeled “17 inch” actually fit standard 17.3 inch laptops. The MATEIN Travel Laptop Backpack is designed to accommodate most standard 17 inch laptops, including models up to 17.3 inches. Its separate laptop compartment offers padding and a secure fit. However, if you own an oversized or extra-thick gaming laptop, you should measure your device first. For more details on laptop sizes, read our Linux laptops for students article.
