Skip the bag fees. Everything you need for 2-3 nights fits in a backpack.
I was standing at the Barcelona airport gate, waiting to board a Ryanair flight to London, when I spotted one of my yoga students walking toward the line.
She looked… bulky.
As she got closer, I counted. Seven tops. All layered on top of each other. And three bottoms: leggings, shorts, and a skirt. All worn at the same time.
She caught my eye, grinned, and gestured to her tiny backpack. “Not paying that fee,” she said.I respect that level of commitment. But you know what? Everything you need for 3 days fits in a backpack. You don’t have to wear your entire wardrobe to the airport, and you don’t have to sweat through seven layers of clothing before you step foot on the plane.

Pack a Weekend Backpack: Start With the Right Size
We’re talking about a standard school or laptop-sized backpack here. Not one of those massive hiking packs with a frame and a rain cover and enough space for a tent.
Just a regular backpack. The kind you’d take to class or the library.Why does this matter? Because budget airlines have gotten strict about carry-on sizes. If your bag doesn’t fit their small metal sizing cage at the gate, you’re paying to put it overhead or check it. And those gate fees are brutal.
Budget Airline Size Limits (Free Personal Item):
Ryanair: 15.7 x 11.8 x 7.9 inches (40 x 30 x 20 cm)
EasyJet: 17.7 x 14.2 x 7.9 inches (45 x 36 x 20 cm)
Wizz Air: 15.7 x 11.8 x 7.9 inches (40 x 30 x 20 cm), 22 lbs max
Spirit: 18 x 14 x 8 inches (45 x 35 x 20 cm)
Frontier: 14 x 18 x 8 inches (35 x 45 x 20 cm)
The key? Soft-sided bags. Hard cases can’t be squeezed if you’re a centimeter over. They will make you pay.
What to Pack for 3 Days: Toiletries First
This is where most people blow it. Toiletries are dense and heavy, and if you’re not careful, one bag of products weighs more than all your clothes combined.
Skip What You Can
Toothbrush and toothpaste? Yeah, you need those. Everything else is negotiable.
Prescription face cream? Bring it. Your signature perfume? Leave it. (Or at least tell yourself you smell fine without it.)
Use What’s There
Does your hotel or Airbnb have shampoo? Conditioner? Body wash? Lotion?
It might not be your favorite brand, but use it anyway. It’s only two (or three) nights.
Buy the Cheap Stuff
If you absolutely need something specific and there’s no room in your bag, buy it when you land. Toothbrush, toothpaste, travel shampoo, whatever. Most drugstores have everything, and you can buy it all for under $10.
That’s still cheaper than paying for that bigger cabin bag.

Go Solid
Solid shampoo bars, solid conditioner bars, solid deodorant. None of these count toward your 100ml liquid limit, and they’re lighter than bottles.
Cut a chunk off a shampoo bar, toss it in a plastic bag, and use it until it’s gone. No leftover product to carry home. More room for souvenirs.
Beyond the obvious toothbrush and travel shampoo, there are a few unexpected items that make weekend travel way easier. I pack the same unusual essentials on every trip, things most packing lists never mention. Check out the 12 unexpected things I always pack in my carry-on for the full list, including the quick-dry laundry trick that’s saved me countless times.
Strategic Showering
Look, I’m not saying you should skip showers entirely. But if you’re only gone for 48 hours, could you shower right before you leave and right after you get back?
72 hours? Pop into a Sephora or duty-free shop and spray some perfume. I won’t tell.
Pack Smart: Footwear (The Most Annoying Thing)
Shoes are the worst. Awkward shape, rarely compressible, heavy. If there were a “most annoying item to pack” award, shoes would win every year.
DO THIS: pick one pair that does double or triple duty.
Comfortable sandals work on the beach, in the city, and out to dinner. Cute sneakers work for walking tours, casual dinners, and the flight itself. Ankle boots handle cold weather, nicer restaurants, and cobblestone streets.
Can you get away with one pair for the whole trip? Do that.
If you absolutely need two pairs, wear the heavier ones on the plane. Yes, even if they’re uncomfortable. Yes, even if they’re stilettos. (I’ve run through airports in heels before. Worth it for the backpack space.)
What to Pack in a Backpack: Clothes
You need clean underwear. That’s non-negotiable. (Unless you’re on a beach trip and living in swimsuits. Then maybe it’s negotiable. Your call.)
Beyond that, it depends where you’re going.
Beach/Summer
Two swimsuits, one coverup, maybe a sundress or shorts for dinner. Done.
Throw in a hoodie or cardigan for the plane and for aggressively air-conditioned restaurants. You’ll be glad you have it.
Winter (Real Winter)
I packed for 4 days in the Arctic Circle in February in a regular backpack. Temperature was around -20°F the whole time. Everything fit, including my giant camera.
How?
I wore everything bulky on the plane. Snow pants over thermal leggings. Winter jacket over a sweater over a long-sleeve shirt. Plus boots. Was I hot on the plane? A little. Was it worth it? Absolutely.
Then I packed: extra underwear (my husband appreciated that), another set of thermal pants, and a few long-sleeve shirts. The trick is you can swap the layers close to your skin without changing the outer layers. Less laundry, and less bulk.
Going somewhere less extreme? Same concept. Wear jeans and a jacket on the plane. Pack extra shirts and maybe a sweater. Wear the bulk, pack the rest.
Spring/Fall
This is capsule wardrobe territory. Pick pieces that mix and match so you can wear them multiple ways.
One blazer, two shirts, one skirt, one pair of pants. That’s four different outfits right there. Add a scarf or swap the shoes (if you brought two pairs), and suddenly you have six looks.
How to Fit Everything in Your Backpack
Rolling beats folding. This isn’t debatable.
Roll your jeans with a t-shirt (or all your shirts). Roll your sweater solo. You’re making tight little bundles that tessellate better in a backpack’s weird shape. Then tuck your underwear in on the sides.
Heavy stuff goes at the bottom, against your back. Shoes, toiletry bag, camera. This keeps the weight balanced when you wear the pack and prevents everything from getting crushed.Soft items (socks, underwear) stuff into gaps. Shoes are hollow. Fill them.
Weekend Packing Tip: What If It Doesn’t Fit?
Wear it.
That’s the answer. That’s the whole strategy.
Extra sweater won’t fit? Wear it on the plane. Are the second pair of shoes too bulky? Wear those too. Heavy jacket taking up half your bag? Wear it through the airport.
Airlines measure bags. They don’t measure bodies.
Will you be warm on the plane? Yes. Will you look like you’re wearing your entire wardrobe? Maybe. Will you save $50+ in baggage fees? Absolutely.
My yoga student wearing seven layers wasn’t ridiculous. She was strategic.
The Actual Strategy
Pack in this order:
- Toiletries (decide what to skip, buy there, or borrow)
- Shoes (one pair, or wear the heavy ones)
- Clothes (fill remaining space with mix-and-match pieces)
At the airport: Wear your bulkiest items. Winter coat, heavy shoes, thick sweater. Frees up massive space in your bag.
The golden rule: If you’re debating whether to bring it, leave it.
The first time you try packing a long weekend into a backpack, you’ll probably overpack. You’ll get to your destination and realize you wore the same outfit twice and never touched that third shirt.
The second time, you’ll forget something important. Probably your phone charger (probably the worst thing to forget).
By the third time, you’ll know exactly what you need and what you don’t. You’ll have your personal minimum figured out.
And once you’ve mastered it, you’ll never want to check a bag again.
No waiting at baggage claim while everyone else walks straight to the exit, no panic about whether your suitcase made the connection, no dragging a rolling bag over cobblestones at midnight trying to find your Airbnb.
Just you, your backpack, and the freedom to move.
