A very impressive bag that packs away into its own top lid, it still has many features you would expect in a top-quality rucksack, yet it can be easily stashed away.
Exped says:
Very lightweight yet tough triple rip-stop nylon makes this featherlight single compartment daypack extremely versatile. It holds gear for summit day or a stroll through an exotic market. It stows in its lid pocket when not in use and fits in any pack or travel bag. Use it on multi pitch climbs, while cycling or paddling. The generous zippered top flap provides easy access and the stretch side pocket holds a water bottle or other items that need to be quick at hand.

Our Verdict
This rucksack has most of the features you would expect, with the added bonus that it packs to almost nothing and can be stashed inside its own pocket. This makes it a fantastic bag for travelling, as it can be used as and when it needed, exploring local towns and markets, but also you have a fully functional day pack that can be used for any short hiking trips.
The bag is constructed of an incredibly robust 100 D triple ripstop nylon, so its incredibly hardwearing. The bag obviously has no internal frame, which makes the bag incredibly light. The shoulder straps are lightly padded but highly breathable and are connected by an adjustable sternum strap to accommodate any body shape; the hip belt strap help reduce bounce, but it’s not really load-bearing, and this can be removed.
