Hi everyone! I’m about to head out on my very first "onebag" journey—a 22-day trip through the Balkans. I'll mostly be staying in hostels, with maybe 1 or 2 nights in an Airbnb for a proper recharge.

I’m using a 55L backpack with packing cubes/organizers.

Here is my current packing list:

• Clothing:
  • 1 Hat (wearing) + 1 to be bought there.
  • 7 Boxers
  • 8 Pairs of socks
  • 2 Technical pants
  • 1 Rain jacket
  • 1 Vest (Gilet)
  • 3 Shorts (2 for outside, 1 specifically for the hostel)
  • 1 Long-sleeve t-shirt
  • 7 Standard t-shirts
• Footwear:
  • Crocs
  • A normal Shoe
• Gear & Tech:
  • Water bottle
  • Daypack (for daily use)
  • Fanny pack
  • Power bank & chargers
  • Portable speaker (not sure)
  • Swiss Army Knife
• Toiletries & Personal Care:
  • Microfiber towel
  • Deodorant & Perfume
  • Pillbox/Medication
  • Sunglasses
  • Sleep mask
• Misc:
  • 1 Notebook & 1 Reading book

My Questions:

1. Am I overpacking or underpacking anything?
2. Is there anything on this list that screams "unnecessary" for the Balkans?
3. Since it's a 55L bag, I’m worried about the weight for a 22-day trip. Any specific cuts you’d recommend?

Thanks in advance for the help!
