Your Guide to Using Vacuum Travel Bags: TSA, Care Tips & Fabric Safety

If you’ve ever sat on your suitcase to get it to close, this one's for you.

Vacuum travel bags are the secret weapon of over-packers, carry-on warriors, and serial adventurers. 

But before you start squeezing the air out of your entire wardrobe, it’s worth knowing a few things: what the TSA allows, how to care for your bags, which fabrics can (and shouldn't) be vacuum-sealed, and how to keep your pump running smoothly.

Whether you’ve just unboxed your TravelPack™ Vacuum Kit or are considering getting one, this guide covers it all.

Can I Bring Vacuum-Sealed Clothes on Flights?

Short answer: yes. Vacuum bags are allowed on flights, both in carry-on and checked luggage. But there are a few TSA-related quirks to keep in mind.

TSA & Airline Packing Rules

Are vacuum bags TSA-approved?
Technically, the TSA doesn’t “approve” products. But vacuum-sealed bags are allowed. That said, if your bag is too compressed and packed into a tight carry-on, TSA agents might have trouble inspecting it and may need to open it.

Carry-on vs. Checked Luggage:
Vacuum-sealed clothes in checked bags? No problem. In carry-ons, just be ready to unzip and show what’s inside if needed. Some agents may want to feel or inspect the compressed items.

Tip: Keep your TravelPack™ Air Pump in an easily accessible spot so you can quickly compress your vacuum travel bag again after TSA agents have asked you to open it.

Vacuum Bag Maintenance Tips: How to Clean & Store Them

Yes, these bags save space, but they also protect your clothes from dirt, moisture, and mystery smells. That is, if you keep them clean as well.

How to Clean Vacuum Travel Bags

Wipe after each trip: Use a damp cloth and mild soap. Avoid harsh detergents that could damage the airtight lining.

Do not machine wash. The heat and spin can ruin the anti-leak zipper seals.

Dry completely: Air dry your bags before storing them. Trapped moisture = mold and mildew. Gross.

How to Store Vacuum Bags Between Trips

1. Keep them flat or rolled, not crumpled.

2. Don’t store them vacuum-sealed long-term. This can weaken the seams over time.

3. Keep away from direct sunlight or extreme heat.

The TravelPack™ Vacuum Bags are made from anti-rip, waterproof nylon, so they’re already built to last. But a little TLC goes a long way.

What You Can (and Shouldn't) Vacuum Pack

Not all fabrics love being flattened into oblivion. Here's a breakdown of which materials are vacuum-bag safe and which to leave breathing.

Fabric Do’s & Don’ts

✅ Safe to Vacuum Pack:

Cotton shirts, t-shirts, socks, underwear – everyday essentials compress beautifully.

Polyester and synthetic blends – bounce back easily after compression.

Denim and casual wear – bulky but resilient.

⚠ Vacuum Pack with Caution:

Wool sweaters – short trips? Fine. Long-term? Risky. Compression can crush wool fibers, making them lose shape.

Down jackets & puffer coats – compress well, but limit long-term storage or risk clumping.

Silk or delicate items – if you must, use a garment pouch inside the vacuum bag.

❌ Avoid Vacuum Packing:

Leather garments – vacuum sealing leather can cause permanent creasing and moisture buildup.

Suede, velvet, or beaded items – these require airflow and care.

Pro Tip: Want to pack a wool coat or blazer? Fold it gently and place it at the top of a partially filled vacuum bag. Light compression only.

Air Pump Charging, Fixes & Vacuum Bag Troubleshooting

The TravelPack™ Air Pump is small but mighty. It’s USB-C rechargeable and lasts up to 20 uses per charge. But if things go sideways mid-trip, here’s what to do.

Air Pump Charge Time

It fully charges in about 2–3 hours via USB-C. The battery light turns green when it’s ready. Charge it before your trip and maybe stash a power bank just in case.

Vacuum Bag Not Sealing? Try This

Check the seal: Make sure the zipper is fully closed. Use the included clip for an airtight finish.

Flatten out bulky clothes: Too many lumps can prevent full compression.

Listen for leaks: If air re-enters, reseal the zip. Still leaking? Check for lint or fabric caught in the seal.

Still not working? Try using a standard vacuum cleaner at home to see if it’s the pump or the bag that’s faulty.

Remember: Your Ekster TravelPack™ Vacuum Kit (vacuum bags and pump) comes with a 2-year warranty. If you run into any issues that you can’t solve, don’t hesitate to reach out to our support team at nest@ekster.com.

FAQ

Are vacuum bags allowed in carry-on luggage?
Yes! Just make sure TSA can inspect them if needed. 

Can you vacuum pack leather or wool?
Wool = short-term only. Leather = no. These materials don’t play well with compression.

What if my vacuum bag won’t stay sealed?
Double-check the zipper closure, smooth out bulges, and use the sealing clip. If air still leaks in, reseal and try again.

How many times can I reuse the TravelPack vacuum travel bags?
They’re made from heavy-duty, anti-rip nylon, built for dozens of uses with proper care.

Can I use the TravelPack pump on other vacuum bags?
Yes! It’s compatible with all standard vacuum bag valves.

How long can you keep clothes vacuum sealed?
For trips, it’s totally fine. But for long-term storage (months or more), let your clothes breathe every few weeks to avoid fabric damage.
