BAGSMART
The hanging hook is sturdy enough for heavy loads, the interior layout fits a full toiletry kit with room to spare, and the water-resistant lining has survived multiple shampoo explosions without staining.
Gonex
Larger than most hanging bags with a reinforced hook that holds 5+ lbs without sagging. Multiple zippered compartments keep liquids separate from dry items, and the exterior pocket fits a full-size hairbrush.
CALPAK
The most durable bag we've tested — the coated canvas exterior wipes clean, the YKK zippers glide smoothly after 100+ trips, and the interior is fully lined with a removable divider.
Travelon
Lays flat in your bag and takes up almost no space when empty. Perfect for weekend trips where you only need the basics. The clear interior pockets make TSA screening fast.
Shacke Pak
Solid water resistance, a functional hanging hook, and enough compartments to stay organized — all for under $20. The mesh pockets are a nice touch for quick-access items.

Hanging bags unfold and hook to a towel bar or shower rod, keeping everything accessible without needing counter space. Flat bags lay open like a book and are more compact when packed. For hotels and Airbnbs where counter space is limited, hanging bags are far more practical. For camping or hostels, a flat bag is easier to manage.
TSA requires all liquids in carry-on bags to be in containers of 3.4oz (100ml) or less, all fitting in a single 1-quart clear zip-top bag. A toiletry bag doesn't replace the quart bag — you still need to remove your liquids at security. Look for a bag with a dedicated exterior pocket for your quart bag so it's easy to grab at the checkpoint.
For weekend trips (2–3 days): a compact flat bag or small hanging bag. For week-long trips: a medium hanging bag with 3–4 compartments. For 2+ weeks or if you carry hair tools: a large hanging bag with dedicated tool storage. When in doubt, go one size larger — a half-empty bag is easier to pack than an overstuffed one.
