What to Pack for Europe: A Carry-On-Only Checklist (2026)

Packing for Europe is mostly an exercise in restraint. The continent is small, weather is moderate almost everywhere outside winter, and laundry is genuinely cheap. Here's the carry-on packing list I've used for trips ranging from a 5-day Paris weekend to a 3-week Italy-Slovenia loop, with notes on what to add or drop by season.

Why carry-on only

It saves €40–€80 per budget-airline flight, eliminates 90% of lost-luggage risk, and forces you to plan an outfit rotation that actually works. After two trips you'll never check a bag in Europe again.

The base list (year-round)

• 5 t-shirts or tops (merino wool re-wears 4+ times before smelling)
• 1 long-sleeve layer + 1 light sweater
• 2 pairs of pants (one casual, one slightly nicer for dinners)
• 1 pair of comfortable walking shoes (broken in!) + 1 pair of casual sneakers or sandals
• 5–7 pairs of underwear and socks
• Light packable rain jacket (essential year-round)
• Sunglasses, sunscreen, a refillable water bottle
• Universal travel adapter, phone charger, small power bank
• Cross-body bag for daytime (anti-pickpocket)

By season

Spring (April–May)

Add a warmer mid-layer and an umbrella. Mornings can be 10°C, afternoons 22°C — the layered approach is essential.

Summer (June–August)

Drop the sweater (keep one long-sleeve for cool Mediterranean evenings), add swimwear, a hat and a second pair of shorts. Linen and cotton beat synthetics in 35°C heat.

Autumn (September–October)

Same as spring, plus a scarf — useful for chilly evenings and as a shoulder-cover in churches.

Winter (November–March)

Swap the rain jacket for a packable down jacket, add a beanie, gloves, thermal long-sleeve, and proper waterproof shoes. You can still do this in carry-on if you wear the bulkiest layer on the plane.

What to leave at home

• Hair dryers and travel irons — every hotel has them
• Heavy guidebooks — your phone is your guide
• More than 1 nice outfit — you'll re-wear it more than you think
• Voltage converters — modern electronics handle 110–240V automatically
