A packable daypack earns its place when you leave your main luggage behind and need a second bag for the day. That might mean a city walk, a day hike or a market run. The useful choice depends on what you carry and how much support you want.
Quick answer
Checked on 19 October 2026. Choose Sea to Summit Ultra-Sil for a light backup bag, or Nanobag for the lowest weight here and short outings. Choose Matador for pockets and padded shoulder straps, or Eddie Bauer if you want a hip belt.

How we compared them
The NomadsToolsLab team read the four makers' product pages on 19 October 2026 and checked each Amazon US listing with a US address. We compared weight, fabric and carrying support. Eddie Bauer alone has a hip belt, while the two lightest options have no back padding.
What makes a packable daypack worth carrying?
A small folded bag is useful only if it suits the outing ahead. For short errands with a light load, minimal padding may be a reasonable trade.
For a longer outing, consider the straps and how you want to organise your things. For rainy days, check the pack's rain protection and keep electronics in a dry pouch.

Figures from the makers' pages, read on 19 October 2026: Sea to Summit, Matador, Eddie Bauer and Nanobag.
Sea to Summit Ultra-Sil Daypack 20L
Sea to Summit Ultra-Sil Daypack 20L
Pick the Sea to Summit Ultra-Sil Daypack 20L if you want a second bag for light daily essentials, because it adds little weight to your luggage. But its unpadded straps make carrying comfort a clear compromise.
The single main compartment keeps the layout simple. There is no hip belt or chest strap, so choose it for outings where minimal support fits what you plan to carry.
Matador 18L Packable Backpack
Matador 18L Packable Backpack
Pick the Matador 18L Packable Backpack if you want separate places for essentials, because its outside pockets let you organise items beyond the main compartment. But there is no padded laptop sleeve.
The maker specifies weatherproof fabric and sealing zippers. That makes water protection part of its appeal, but the maker explicitly excludes use under water.
Eddie Bauer Stowaway Packable 20L Daypack
Eddie Bauer Stowaway Packable 20L Daypack
Pick the Eddie Bauer Stowaway Packable 20L Daypack if a hip belt matters, because it is the only option here that includes one. But its water-repellent finish does not make it waterproof.
That belt is the clearest reason to choose it over the other packs in this comparison. If you do not want a hip belt, use folded weight and pocket layout to guide your choice instead.
Nanobag Daypack 16L
Nanobag Daypack 16L
Pick the Nanobag Daypack 16L if you want a bag for short, light outings, because it takes up little room when folded. But it has no back padding or chest strap.
The maker states a high carrying capacity, but that claim does not describe carrying comfort. Keep the intended outing in mind before filling a bag with so little support.
Choose for the outing you actually take
For a market run or short city walk, start with how much you expect to bring back. Nanobag and Ultra-Sil suit the role of a light backup, provided you accept their limited support.
For day hikes, consider support before folded size. Matador offers padded straps and a removable chest strap, while Eddie Bauer offers the hip belt. For a longer walk, check the packed weight and how much support you need. Packing the main bag too? Our packing cubes guide and 40x30x20 cabin backpacks help with the rest.
- Ultra-Sil suits light backup use, with the maker recommending a modest load for comfort.
- Matador offers outside organisation and padded straps, but no padded laptop sleeve.
- Eddie Bauer is the hip belt choice here, with water-repellent rather than waterproof fabric.
- Nanobag saves the most weight, with limited support for longer outings.
