25 Best Travel Accessories for One Bag Travelers

As a minimalist traveler and long-term expat based in Asia, I only carry what I truly need. I slow travel for months at a time with a single carry-on backpack (always under 7kg to meet budget airline rules) and a compact sling bag for daily essentials. Every item I pack is lightweight, durable, and personally tested through years of real-world travel. This isn’t a generic packing list — it’s exactly what I wear, carry, and use every day while navigating busy cities, switching hotels, riding buses and trains, and exploring new places on foot. Whether you’re a digital nomad, backpacker, or just trying to pack lighter, here are my 25 best one bag travel accessories for 2025 — all available on Amazon.

1. Osprey Daylite Travel Pack 35L 

After years of one-bag travel, I switched to the Osprey Daylite 35L Travel Pack for its lightweight design, smart organization, and perfect size for carry-on travel. At just over 2 lbs, it’s incredibly comfortable to wear thanks to the breathable AirScape™ backpanel, and the suitcase-style clamshell opening makes packing and unpacking a breeze. It fits in most airline overhead bins, has a TSA-compliant laptop sleeve, and includes thoughtful features like lockable zippers, tuckaway backpack straps, and side water bottle pockets. I find 35L to be the sweet spot for minimalist, long-term travel — roomy enough to fit everything I need, without being bulky or heavy. As with all Osprey products, it comes with their lifetime warranty, and I’ve been a fan of their quality and durability for years. This is now the main backpack I use for all my slow travel adventures.

It’s the perfect size for my passport, phone, wallet, mints, tissues, and other small essentials, without weighing me down or bulging awkwardly. This sling is incredibly comfortable to wear across the chest or back, and it stays secure while navigating crowded places.

The RFID-blocking tech adds peace of mind, and it even has a hidden pocket for sensitive documents. I love that it fits comfortably in my front pocket or sling without bulging.

4. Compression Packing Cubes

Compression Travel Bags

Compression cubes are one of the best travel essentials for one bag travel — they help you organize your gear while saving serious space. The concept is simple: overpack the cube, press it down, zip the compression layer, and it shrinks into a compact block that fits neatly into your backpack. I personally use them to separate winter and summer clothes, and the smaller ones are perfect for underwear and socks. They’re also great for keeping dirty laundry isolated, so odors don’t mix with clean items. These cubes are lightweight, easy to pack and unpack, and make it much easier to stay organized.

5. Osprey Ultralight Zip Organizer 

The Osprey Ultralight Zip Organizer is my go-to toiletry bag for long-term travel. It’s water-resistant, tear-resistant, and lightweight, yet surprisingly spacious. I use it to carry all my essentials — medications, beard shaver, lotion, Q-tips, nail clippers, tweezers, toothbrush, and toothpaste — and it still packs flat into my backpack. One of the best features is the built-in hook, which makes it easy to hang in shared bathrooms or small hostel sinks, keeping everything accessible and off wet surfaces. Whether you’re staying in guesthouses, hotels, or dorms, this bag keeps your grooming gear organized without adding bulk. Minimalist travelers will appreciate how light and efficient it is — it just works.

6. Braun All-in-One Style Series 5

I travel with the Braun Series 5 All-in-One Style Kit because it’s compact, lightweight, and gives me everything I need to keep a neat beard on the road — without paying for barbershops. It comes with grooming attachments including a beard trimmer, ear and nose trimmer, and precision detailing tools. The Precision Wheel offers 40 length settings, so I can dial in exactly how I want my beard to look. It’s small enough to fit into my toiletry bag and has enough battery life (up to 80 minutes cordless) to last weeks between charges. For minimalist travel grooming, this kit delivers serious value — and it’s already paid for itself multiple times over.

The iPad Mini is the one device I never travel without.
