Packing seems obvious. Yet, the majority of travelers arrive at their destination with an overweight suitcase, wrinkled clothes, and useless items. Worse: they've forgotten the essentials. This guide provides you with the complete method for packing perfectly for every trip — with the universal checklist to download.
Why most people pack incorrectly
The most common mistakes
- Packing the night before: you'll always forget something
- Bringing clothes you never wear at home: you won't wear them on your trip
- Neglecting the weight of shoes: they often account for 30% of the total weight
- Not compressing: without a compression bag, you lose 50% of your space
- Putting liquids anywhere: risk of leaks and security issues
What experienced travelers do differently
Frequent travelers plan their outfits before taking out a single item of clothing. They choose versatile pieces in neutral colors. They compress their bulky clothes. And they check the weight of their luggage 2-3 days before departure — not the night before.
Step 1: Plan before packing
List your activities day by day
Before taking out a single item of clothing, note down your activities day by day: beach, restaurant, hiking, evening. Assign an outfit to each activity. This is the only way to avoid "just in case" clothes that account for 40% of the weight of an average suitcase.
How many days before departure should you pack?
Ideally 2-3 days before. This gives you time to check the list, wash necessary clothes, and add forgotten items without stress. On the day of departure, all you have to do is add last-minute items (chargers, medications, documents).
Step 2: Select the right clothes
The neutral color rule
Black, white, gray, beige, navy: these colors all combine with each other. 5 pieces in neutral colors create more outfits than 10 colorful pieces that don't go together. This is the principle of the capsule wardrobe applied to travel.
Materials to prioritize
Merino wool, technical polyester, nylon: these materials dry in 2-3 hours, resist odors, and don't wrinkle. A merino t-shirt can be worn 3 days in a row without odor. Avoid thick cotton (heavy, long to dry) and linen (wrinkles too easily).
The 5-4-3-2-1 method for a week
5 underwear and socks, 4 tops, 3 bottoms, 2 pairs of shoes, 1 jacket. 15 pieces maximum for 7 days. With neutral colors, these 15 pieces create more than 20 different outfits.
Step 3: Compress and organize
Why compression is essential
Without compression, your clothes leave 50% empty space in your suitcase — air trapped between the fibers. A compression bag extracts this air and reduces volume by half. Result: a week's worth of clothes fits in a standard carry-on.
The BagSlim compression bag
The BagSlim is the most effective solution: integrated USB-C electric pump, 50% compression in 5 seconds, usable on the way out AND on the way back without a vacuum cleaner. Place your compressed clothes at the bottom of the suitcase, shoes on the sides, accessories in the middle, necessities on top.
Organization by zones
Bottom: compressed BagSlim bag + shoes on the sides. Middle: electronics and accessories. Top: pajamas, toiletry bag, everything you'll need first upon arrival. Outer pockets: documents, chargers, what you need at the airport.
Step 4: Manage liquids and electronics
Rules for liquids in carry-on
In carry-on, each liquid must be in a container of 100 ml maximum, all in a transparent plastic bag of one liter. Alternatives: solid products (solid shampoo, solid soap, solid deodorant) or purchase on site. A solid shampoo replaces a 250 ml bottle and is universally accepted.
Electronics not to forget
- Phone charger + universal adapter if needed
- Power bank (max 100 Wh allowed in cabin)
- Earphones
- USB-C cable to charge the BagSlim
Step 5: Check before leaving
Weight and dimension check
Weigh your suitcase with a travel scale. Check the dimensions allowed by your airline (Ryanair and EasyJet: 55x40x20 cm). If too heavy: wear your heaviest item on the plane (coat, boots, thick jeans).
Final check
Documents (passport, tickets, insurance), essential medications, chargers, house keys to entrust to someone. Take a photo of your open suitcase before leaving — useful in case of lost luggage.

Packing according to travel type
Suitcase for business travel
Prioritize wrinkle-resistant materials (technical polyester, fine wool). Compress your casual clothes in the BagSlim and lay your shirts flat on top. For 3-4 days, everything fits in a carry-on — you avoid waiting for luggage and get to your meeting faster.
Suitcase for hot destination
Light clothes take up less space, but swimsuits and towels compensate. Compress towels in the BagSlim: they lose 60% of their volume. Buy sunscreen and shower gel on site.
Suitcase for cold destination
This is where the BagSlim is most impressive. A compressed down jacket loses 60-70% of its volume. Two thick compressed sweaters fit in the space of one. Wear your coat on the plane.
FAQ — How to pack your suitcase
How to fit more in your suitcase?
The most effective combination: BagSlim compression bag (50% less volume) + rolling clothes + shoes padded with socks. You can double the effective capacity of your suitcase without buying a larger suitcase.
How to avoid wrinkles in your suitcase?
Use the bundle packing technique for shirts and dresses: wrap them around a central core (toiletry bag). For other clothes, rolling produces fewer wrinkles than classic folding. Consult our folding techniques guide.
Which suitcase to choose for light travel?
A rigid 35-40L carry-on for urban travel, or a 20-30L backpack for active travel. Make sure the empty suitcase weighs less than 2 kg to maximize your usable capacity.
