5. Bring a Foldable Bag Just for Souvenirs
This is the ultimate pro move: pack a lightweight, foldable duffel or tote bag in your luggage. On your return trip, it becomes your carry-on or check-in for all the goodies you picked up. The Baggu nylon duffel or Paravel Fold-Up Bag are stylish, compact, and airport-approved.

6. Toiletries: Travel Sizes + Solid Versions
Instead of lugging full-sized shampoo or lotion bottles, invest in refillable travel containers or better yet—go solid. Shampoo bars, solid moisturizer sticks, and toothpaste tablets are leak-proof, eco-friendly, and TSA-approved. Less mess, more room.
