A smaller capacity rewards a clear list
Shoes or a bulky warm layer can consume a meaningful share of 28 liters. Decide which items are essential before choosing this size, and include any computer equipment in that calculation. Compared with 40 liters, the smaller stated volume may encourage a simpler load, but the title does not establish empty weight or guarantee easier carrying.
Personal-item language needs measurements
Under-seat limits vary, and a pack’s shape matters independently of its total volume. Obtain height, width and depth, then account for pockets that may bulge when full. Confirm the laptop arrangement if needed and check what the PFAS-free claim covers. Neither that material wording nor the TSA reference substitutes for practical fit information.
