Expandable 18 L Daypack

The Osprey Ul Stuff Pack is an ultralight, collapsible backpack that adds 18 litres of capacity when you need it and packs into its own tiny footprint when you do not. It suits travellers who want a single bag that can expand for day trips or souvenirs without committing to a second full-size pack.

Check packing space and strap fit

Verify that your main luggage has room for the packed bundle, which measures 2 by 6 by 5 inches, so it slips into a suitcase corner or overhead pocket. The padded mesh shoulder straps and adjustable sternum strap with whistle are sized for unisex use, but torso length is not adjustable, so very tall or short wearers should confirm comfort before a long day out.

Weight, breathability and load feel

At .329 lb the pack adds negligible mass, and the 40D high-tenacity nylon is bluesign approved and GRS-certified 100 percent recycled. Breathable mesh straps promote airflow on warm days, while dual stretch side pockets and an internal key clip keep small items organised without shifting the centre of gravity when the main compartment is lightly loaded.
