Size & Design: One‑size scientific silhouette with generous capacity. Multi‑compartment interior easily fits a 15.6‑inch laptop, A4 notebooks, water bottle, folding umbrella, and 2‑3 changes of clothes — ideal for daily commuting, campus life, and short trips. Curved S‑shaped padded shoulder straps follow body contours, and breathable back padding reduces fatigue and sweating during extended wear.
