A sling bag is usually worn close to the body with one strap. Crossbody mainly describes how a bag is worn, with the strap across the body. The names overlap, so compare the actual model, strap length and layout.
What to check
Compare both carrying styles with your usual belongings. Adjust the straps and reduce unnecessary weight. Comfort depends on fit, load and your own preference.
Outer dimensions describe the outside of a bag. They do not give the clear space in the laptop compartment or usable capacity. A fixed deduction or correction factor cannot reliably determine these. Compare the internal dimensions and opening with your belongings.

Leather care
