How is SRC different from rolling vs folding or other packing techniques?

SRC is a categorization system, not a compression technique. You still choose whether to roll or fold your clothes. SRC tells you what goes together and in what order. You can use SRC with packing cubes, stuff sacks, or no organizers at all. It works with rolling, folding, or bundle packing.

Do I need three separate packing cubes for this to work?

No. Packing cubes make it easier, but the mental framework works without them. You can use gallon freezer bags, stuff sacks, or just pack in three distinct zones of your bag. The point is keeping the three categories separate so you can access what you need without unpacking everything else.

What about items that don't fit in Sleep, Routine, or Clothing?

Most travel items fit into R (Routine). Your book, travel documents, snacks, water bottle, day bag, umbrella—these are all part of your daily routine. If something truly doesn't fit, it probably doesn't need to come. The few exceptions (gifts you're bringing, special equipment for a specific activity) can go in a fourth category, but resist making this a catch-all.

Does this work for carry-on only travel?

Yes, and it's especially useful for carry-on. When you only have limited space, the SRC method helps you identify exactly what's essential to your actual routines versus what you think you might need. Most carry-on packers find the R category reveals redundancies—three ways to charge your phone, two types of moisturizer—that they can eliminate.

How do I use SRC for a multi-climate trip?

Your Sleep and Routine categories stay mostly the same regardless of climate. Your Clothing category adapts. For a trip from cold to warm, you might wear your bulky jacket on travel days and pack only warm-weather clothes in your C cube. Some people use two C cubes for dramatic climate changes—one for each climate—and swap them as needed.

How to Pack Using the SRC Method

The SRC (Sleep, Routine, Clothing) method divides your packing into three categories: what you need to sleep, your daily routines (hygiene, tech, health), and what you wear. This system makes packing faster, prevents you from forgetting essentials, and helps you repack efficiently during your trip.

Start with Sleep (S). List everything you need to sleep comfortably. This includes sleepwear, any sleep aids (eye mask, earplugs, melatonin), medications you take at night, phone charger (if you use your phone as an alarm), and travel pillow if you use one. Pack these items in one section of your bag or in one packing cube. You'll always know where your sleep essentials are when you arrive tired at a new place.
Build Your Routine (R). Write down your actual daily routine from morning to night. Toothbrush and face wash go here, not with clothing. So do your laptop, charging cables, headphones, contact lens supplies, medications, sunscreen, and anything else you use daily regardless of what you're wearing. Group these by when you use them: morning routine, daytime carry items, evening routine. Use a toiletry bag for hygiene items and a tech pouch for electronics.
Plan Your Clothing (C). This is the only category most people think about, which is why they overpack. With S and R handled, you can focus purely on clothes and shoes. Plan outfits by activity, not individual items. Pack one outfit for each type of day you'll have, plus one backup. For a week-long trip, this typically means 4-5 tops, 2-3 bottoms, 1-2 pairs of shoes, and appropriate undergarments and socks.
Pack in SRC Order. Pack Sleep items first, usually at the bottom or in an easy-access pocket. Pack Routine items next, organized in their pouches. Pack Clothing last. This order means you can live out of your bag without unpacking everything, and you can grab what you need in any situation without digging through clothes to find your toothbrush.
Use the SRC Check. Before you leave each accommodation, do a quick SRC sweep. Check the bed area for Sleep items, bathroom for Routine items, closet and drawers for Clothing. This three-zone check is faster than random searching and catches forgotten items every time.
