Why it gets packed
1–4 weeks · Optional
Beach day, a day trip to Toledo, a picnic from the mercado. A tote does not zip; this does.
1–4 weeks · Required
20L for the Vatican line, a regional train, and a table at a bar where a hiking pack is not welcome.
1–4 weeks · Required
20L for the Tube, a coach to the Cotswolds, and a museum day. The suitcase stays at the hotel.
1–4 weeks · Required
20L for the RER B, a museum bag check, and a café table. The suitcase stays at the hotel.
1–3 months · Required
20L for the Yamanote at 8:40 a.m., a konbini run, and a day in Nara. A 40L on your back in a packed car is rude here.
1–3 months · Required
20L for line 2 at rush hour. A larger pack on your back in a Seoul subway car is how you apologize all month.
1–3 months · Required
20L for a ferry, a tram, and a coastal walk. Australian sun plus a big pack is how you arrive tired.
10–14 days · Optional
Only if the 40L is too big for a museum day. Many museums make you check anything larger than a daypack.
2–8 weeks · Optional
For class and weekend trips if your own backpack has open pockets. This one zips fully shut; wear it in front on a crowded metro.
12–16 weeks · Optional
For class and weekend trips if your own backpack has open pockets. This one zips fully shut; wear it in front on a crowded metro.
2–8 weeks · Required
20L for the Vatican line, a regional train, and a table at a bar where a hiking pack will not be welcome.
2–8 weeks · Required
20L for the Tube, a National Express coach, and a library day. The 40L stays in the room — London peak hours are not a hiking trail.
2–8 weeks · Required
20L for the RER B, a museum day bag check, and a café table. Leave the hiking pack in the chambre de bonne.
12–16 weeks · Required
20L for the Yamanote, a convenience-store run, and a seminar. Japanese trains are not the place for a 40L on your back at 8:40 a.m.
12–16 weeks · Required
20L for line 2 at rush hour. A larger pack on your back in a Seoul subway car is how you apologize for 16 weeks.
12–16 weeks · Required
20L for campus, a ferry, and a tram. Australian sun plus a hiking pack is how you arrive at seminar already tired.
10–14 days · Required
This is the bag. Museum days, the coach overhead, a café. If you also packed a 40L, unpack the 40L.
