Reviewers reported that the magnetic Fidlock buckle can rarely disengage when the strap is pulled in opposing directions at a particular angle. The rear stealth pocket is well hidden and suitable for extra-secure slim items including passports, travel documents, and important IDs. The permanently attached strap is wide enough to distribute a fully packed main compartment's weight, and reviewers found its fit comfortable.
The sling can be worn at the hip for relaxed daily carrying or shifted to the front or back for biking and airport rushing. The main fabric is 1680D CORDURA Ballistic Nylon, and its heavy denier gives the sling a structured feel.
Reported strengths
- The reviewer found that the Aer Day Sling 3 stands upright, making its wide main-compartment opening easier to access and sort through.
- The main compartment provides multiple mesh pockets, a zippered divider, and a device sleeve sized for an iPad Mini or Nintendo Switch.
- The rear stealth pocket is well hidden and suitable for extra-secure slim items including passports, travel documents, and important IDs.
Reported trade-offs
- The front compartment is a simple dump pocket after its two stretchy pockets were removed, leaving its key strap as the only organization.
- Reviewers reported that the magnetic Fidlock buckle can rarely disengage when the strap is pulled in opposing directions at a particular angle.
- Because the main strap is non-removable, it dangles when the sling is carried by the handle, although stuffing it into the rear pocket helps.
