Pros and cons

Pros

Compact 1.2-litre capacity and 140-gram listed weight suit carrying a small selection of essentials.
Adjustable three-strap fastening allows removal without a permanent frame fitting.
The phone window supports viewing and touch operation without taking the phone out of the bag, according to the listing.

Cons

The 1.2-litre capacity limits how much larger gear it can carry alongside a phone and everyday essentials.
Phone compatibility is specified only for devices under 6.5 inches, so fit depends on the phone's actual dimensions and case.
