Leave the main luggage at your accommodation and take only what the afternoon needs. That is a natural role for the Osprey Daylite Plus, which also serves the ordinary commute between trips.
A place for the layer you keep removing
Osprey's Daylite Plus description includes a panel-loading main compartment, two bottle pockets and front storage for smaller belongings and a loose layer. These features suit a day that moves between transport, outdoor walking and indoor stops. Keep the jacket accessible while placing charging equipment or other items that need containment inside.
The linked model page describes a multifunction sleeve for a hydration reservoir, tablet or many 14-inch laptops. That flexibility does not mean every computer fits. Measure your own device and check the selected version, particularly if it has a protective shell or a thick hinge.
Use it as a companion with a clear job
A small day bag works best when the larger luggage carries clothing and bulky spares. Put water, the current layer, daily electronics and the few objects needed in transit into the Daylite Plus. Avoid filling it with duplicate toiletries or multiple backup chargers merely because they fit.
Some Osprey packs accept Daylite attachments, but compatibility depends on the particular main pack. Confirm the connection method before planning to carry the two as one system. If you will use it independently, assess strap fit with a full bottle and laptop inside. A comfortable destination setup depends on the load you actually carry, not on how little an empty daypack appears to weigh.
