Is this backpack good for school?

Yes, for light school use. It has three zippered pockets, a laptop or tablet sleeve and a bottle pocket, and it weighs about 1.3 lbs. It lacks a structured frame, so heavy textbook loads will sag.

Will it fit a laptop?

There is an inside compartment sized for a laptop or tablet. The bag measures about 18.1 in tall and 11.8 in wide, so most standard laptops fit, but measure your device against those dimensions first.

No. The polyester resists moisture and dries quickly, but the seams and zippers are not sealed. Use a rain cover or dry bag in steady rain.

Empty the bag, pretreat stains, then scrub with a cloth or soft brush using warm water and laundry detergent. Air dry it; do not machine wash or tumble dry.

Is it good for hiking?

It works for short, light walks but not serious hikes. There is no hip belt, frame or ventilation channel beyond the mesh panel, so it suits casual outings rather than long trails.
