Here’s a summary of the laptop bag you asked about — and whether it matches what you likely expect.
HP Prelude 15.6‑inch Laptop Bag Backpack 2Z8P3AA
The bag supports laptops up to 15.6" diagonal, so it’s compatible with many Apple, HP, Dell and other 15.6″ models.
External material is 100% polyester with a water-resistant coating, which helps against light rain/splashes (but it isn’t fully waterproof).
Internal structure: padded compartment for the laptop + separate pockets/slots for accessories (e.g. charger, mouse, pens, etc.) — useful if you carry more than just the laptop.
Size & Weight: about 31 × 10.5 × 45.5 cm, and weight around 0.38 kg, so it’s quite light compared to bulky backpacks.
The bag has a shoulder strap/backpack straps (depending on version or usage) and can be attached to a rolling suitcase for travel — suitable for commute or travel use.
Carrying a single laptop (up to 15.6”) + associated accessories (charger, mouse, notebooks, cables) — good for work, study or commuting.
Light travel or daily commuting: because it’s light and compact, easier to carry than bulky backpacks, and fits comfortably under seats or overhead in public transport.
People who prefer simplicity and minimal bulk — not a large “tech-loadout” backpack, but a neat, practical bag for daily essentials.
Because it’s fairly slim/light, it might not hold bulky extras (e.g. large headphones, books, thick folders, large water bottles) comfortably — ideal if you mostly carry the laptop + small accessories.
Water resistance only — if you expect to walk often in heavy rain, consider adding a rain cover or choosing a fully waterproof bag.
If you have a 16”+ laptop (some larger models, or newer laptops with big screens), it may not fit. The bag is explicitly sized for up to 15.6".
