My One-Bag (30L) Packing List for Full-Time Four-Season Travel (2025 Edition)

My One-Bag (30L) Packing List for Full-Time Four-Season Travel (2025 Edition)

I've been one-bag traveling for years, having gradually whittled down to an everyday-sized 30L from a 55L. Ditching the suitcase has changed how I move: I can actually do things between checkout and late (cheap) flights (specially when Airbnbs won’t store luggage), and I can slip onto public transit from the airport without looking like an obvious tourist. On the plane, having a true everyday-sized backpack as my main bag keeps my leg space free and saves me from spontaneous gate-checks. (Read my reflections on why I’m drawn to one-bag, minimalist travel here).

This packing list has held up across all kinds of weather, from humid, hot beach days in Hawaii to freezing, wind-shipped nights in the Atacama desert. Below is my current gear list for full-time, four-season travel.

TL;DR: If you only get 8 things from this list

  1. Main backpack: Patagonia Refugio 30L (*) — My ride-or-die for years: square shape fits more than it looks, carries like a true everyday bag, and has great organization.

  2. Essentials sling: Osprey Ultralight Collapsible Stuff Waist Pack (*) — Small, secure day carry for flights, transit, and walking around without hauling my whole pack.

  3. Compression packing cubes: Eagle Creek Pack-It Isolate (S & M) (*) — 4 years of hard use (including 2 years as my everyday “closet”) and still like new; the #1 reason all my clothes fit.

  4. Shoe bag: Peak Design Shoe Pouch (*) — Volume-efficient and perfectly sized for the bottom of my pack, with sturdy fabric that fully contains dirty shoes.

  5. Insulated jacket: Patagonia Nano Puff Hoody (*) — Warm, durable, and extremely packable; I stash it in my backpack’s side mesh pocket so it doesn’t take interior space.

  6. Trail runner sneakers: Nike Pegasus Trail Running Shoes (*) — My single “do-everything” shoe for road running, hiking, and sightseeing.

  7. Travel adaptor charging block: Epicka Universal Charging Adaptor (*) — My long-time go-to (I use it even at home): works across plug types worldwide and supports both USB-A and USB-C.

  8. Laundry solution: Scrubba Wash Bag (*) — Waterproof, packs small, and lets me wash clothes anywhere with built-in scrubbing bumps.

Packing System

Notes: 

  • My backpack is my suitcase – everything I need for everyday living goes in there. My sling is my always-on-me bag — my travel essentials and important items (passport, wallet, etc) go there.

  • My clothes live in two packing cubes: M = tops/layers, S = socks/underwear/bras, so I never fully unpack.

  • All my liquids, which include toiletries and makeup, live in my clear toiletry pouch. I also barely unpack this at my destination.

  • I now have a way of packing everything into my backpack that works for me, so packing and unpacking take no time (shoe bag goes on bottom, then compressed packing cubes, toiletry pouch goes to the side, etc).

Travel essentials like passport, wallet, portable charger, and AirPods go into my Osprey 2L sling, so they’re always with me when I travel.

Packs (2)

Organization (3)

  • 2× Packing cube (compression, ultralight) (currently: Eagle Creek Pack-It Isolate S & M (*)) — 4 years of use (2 years as my “closet”), still like new. Revolutionary for fitting all my clothes into my pack.

  • 1× Toiletries pouch (transparent, TSA-compliant) (currently: Tom Bihn Clear 3D Organizer Cube) — Ultralight but spacious. The clear design makes airport liquid checks (especially stricter ones like Heathrow) painless.

Separation & Laundry (2–3)

  • 1× Shoe bag (fits 1-2 pairs, non-mesh) (currently: Peak Design Shoe Pouch (*)) — Volume-efficient and sized to sit perfectly at the bottom of my backpack, with a sturdy zipper and solid fabric that keeps dirty shoes fully contained away from the rest of my clean stuff.

  • 1× Laundry bag (breathable or wipeable) (currently: mixed)

Pouches (3)

  • 1× Tech pouch (structured, cable-friendly) (currently: Tropicfeel Fidlock Pouch)

  • 1× Misc pouch (catch-all, zippered) (currently: mixed)

Clothing Capsule

Notes: 

  • All my clothes are of a neutral color palette so everything can mix and match into multiple outfits.

  • I opt for quick-dry and low-odor materials – so lots of merino wool and lightweight synthetics vs. heavy cotton. 

  • I love multifunctional clothing that can serve as athletics wear, lounge wear, and look good enough for a nice dinner. 

  • I tend to run warm so I don’t have too much gear for cold weather, but if you run cold, you might need to swap for warmer jackets or bring additional mid-layers. 

  • Note: Many of my merino pieces are from Unbound Merino (*) simply because I like the fit and style, and I’ve had good durability. I am an affiliate with the brand for those reasons. But the overall principle is “lightweight merino basics.”

Bottoms (5)

Tops (5)

One-piece (1)

Outerwear (2) 

  • 1x Insulated jacket (packable, versatile) (currently: Patagonia Nano Puff Hoody (*)) — This classic has been my favorite puffer for years. Warm, durable, and extremely packable, it fits into the side mesh pocket of my backpack so it does not take any space inside my pack. It’s technical for the outdoors but still sleek enough for the city. Overall, the perfect all-rounder.

  • 1x Windbreaker (extremely packable, lightweight) (currently: Decathlon Kiprun Packable Windbreaker; similar Patagonia Houdini Jacket (*)) — Mine is not in stock anymore, but I love a windbreaker that packs into the size of a phone. Makes it a breeze to bring out on runs or to have a versatile layer for ultralight packing. 

Underlayers (14)

Footwear (2)

Optional depending on destination (2)

  • 1x Rain jacket (packable, heavyduty) (currently: REI XeroCloud 3L Rain Jacket) — A 3L (3-layer) rain jacket is the most robust type. I bring this when the destination will be rainy, snowy, or very cold. This one in particular is also stretchy and comfortable.

  • 1x Bikini swimwear (simple, black) (currently: mixed)

Toiletries

Notes: 

  • All of the items below fit into my Tom Bihn toiletries pouch.

  • For long-term travel, I aim to bring about 2-3 weeks worth of easily replaceable toiletries, like contact solution and toothpaste, to keep the volume down.

  • For items that are not easily replaceable, like contacts, I always bring a bit more than strictly necessary, just in case. 

Basics

  • 1× Toothbrush (with hygienic cap)

  • 1× Toothpaste (travel size)

  • 1x Tiny mirror

Contacts

  • 12× Contacts (6 months worth of monthlies)

  • 1× Contact lens solution (travel size)

Skincare (liquids)

  • 1× Face moisturizer

  • 1× Body moisturizer (travel size)

  • 1× Sunscreen (travel size)

Makeup

  • 1× Brow gel

  • 1× Eyeliner

  • 1× Mascara

  • 1x Concealer

Tech and Miscellaneous

Notes: 

  • My laptop and Kobo e-reader go into my backpack’s laptop sleeve.

  • All my tech chargers go into my tech pouch packed into my backpack. 

  • With me in my sling to use on the plane, I carry my Airpods, bluetooth connector for earphones, a USB-A to USB-C cable for charging, and my portable charger.

Tech 

  • Laptop (14-inch Macbook Pro)

  • Kobo e-reader

  • Airpods

Tech chargers

  • Travel adaptor charging block (currently: Epicka Universal Charging Adaptor (*)) — I’ve been using this one for several years now, even as my regular charging block in the US. It’s adaptable to 4 different plug types usable across 200+ countries and compatible with USB-A and USB-C cables. 

  • Charging block for laptop

  • 3x cables (USB-C to USB-C, USB-A to USB-C, Mac cable) 

Tech accessories

  • Portable charger (currently: Nllosa 5000 mAh (*)) — Provides one full charge for my phone, necessary for long travel. Small and not too heavy. 

  • Bluetooth connector for earphones (currently: Avantree SoundJet R1 (*)) — Works great for using your bluetooth earphones on the plane rather than the crappy plane ones. 

Miscellaneous necessities

  • Razor

  • Nailclippers

  • Tweezers 

  • Feminine hygiene products

  • Medicine and first-aid (painkillers, antacids, bandaids)

  • Glasses

  • A couple of Ziploc bags (separation and protection in a pinch)

Portable Laundry System

Notes: 

  • I bring this if my destination won’t have easy access to laundry. 

  • I actually used this handwashing system for a month in an Airbnb that did not have laundry, and it worked very well. 

  • Hand-washing is gentler on your clothes, saves you money on laundromat, and gives you a good arm workout :)

Laundry system

  • Wash bag (packs small) (currently: Scrubba Untouched Wash Bag (*)) — The bag has bumps on one end to effectively scrub your clothes and is waterproof so you can do it anywhere. Each load takes a few minutes of scrubbing, but loads are pretty small.

  • Detergent sheets (super portable, non-liquid, no mess) (currently: Journey Breeze Travel Laundry Detergent Sheets (*)) — I use 4-5 sheets per wash. Light floral scent. 

  • Drying clothesline (super portable, dry anywhere) (currently: Sea-to-Summit Lite Line (*)) — Sturdy, adjustable in length, and packs tiny into itself, with beads to hold your clothes in place.
