Overview
A phone-and-wallet day is the situation for this small black sling, worn across the body on an adjustable strap. One zippered compartment and two pockets cover the basics in light polyester.
The reason to choose it is hands-free carry for a few items, in a light package. Capacity is small, so layers or a bottle will not fit.
Who it's for
A traveler or commuter carrying a phone, keys and a small tablet. Hikers or students with books should choose a larger pack.
Pros and cons
- Hands-free cross-body carry
- Water resistant fabric
- One main compartment
- Hand wash only
Performance notes
A single strap across the body carries the load on one shoulder, so a heavy fill tilts the bag. Water resistant fabric handles light rain. The small volume limits the load, which helps comfort.
