Are there any comfortable daily bags for my younger brother returning to school for semester 2?

I've narrowed down bags with plenty of room to carry books and personal items for commuting and everyday life. MARGESHERWOOD's tote bag comes in a generous size that holds up to a 17inch laptop, and YEOMIM's shoulder bag is practical as it fits a 13inch laptop and offers daily water resistance. KHIHO's shoulder bag features a zipper closure and a horizontal silhouette, making it great for packing belongings securely.

From the options in the KRW 100,000 range, I selected bags with sizes and practicality well-suited for college students' daily use. AMOMENTO's backpack is made of lightweight nylon and offers efficient storage with side mesh pockets and a front zipper pocket, while KHIHO's 3-WAY backpack has a 13inch laptop pocket and a side zipper, making it convenient to carry books and devices together. If you prefer a shoulder style, KHIHO's stud bag, with its generous 49.5cm width and adjustable handle height, is also a great fit.

From the options in the KRW 100,000 range, I've gathered nylon backpacks that are great to wear for commuting to school after returning. The AMOMENTO backpack features mesh pockets and a front zipper, making it easy to separate belongings lightly, and KHIHO's 3-WAY backpack has a pocket for storing a 13inch device and a side zipper, making it easy to take out books and devices.

Among the candidates, 2 types of KHIHO backpacks are most suitable for storing a laptop, as they feature a dedicated pocket for a 13inch device and a securing strap. The AMOMENTO backpack was excluded because, although its storage layout such as mesh and zipper pockets is good, official materials do not specify a separate laptop slot or whether it can accommodate one. The two products differ only in color: black and light grey.

Matching your requested conditions, I've narrowed it down to the 3-WAY backpack in black featuring a dedicated pocket for a 13inch device and a securing strap. Excluding the light grey color you looked at together, I'm presenting this one alone.
