Frequently Asked Questions
Will these bags fit a 15–16" laptop?
Baosha and CROCOD are designed to accept up to 17" laptops, so a 15–16" laptop fits comfortably. MOSISO targets 13–14" devices—double-check the computer compartment dimensions before buying if you have a 15–16" laptop.
Which bag is easiest to carry all day?
Baosha’s ergonomic design and dispersed straps make it the best choice for all-day carrying. MOSISO is lighter but has less padding and space; CROCOD is durable but may be heavier when fully loaded.
Are these bags water-resistant for walking between buildings?
MOSISO uses waterproof PU leather and offers the best splash resistance. CROCOD and Baosha are canvas — they tolerate light drizzle but benefit from an external rain cover for heavier exposure.
