Compression Sac Review

Eagle Creek’s Pack-It Compression Sac is one of the best ones in the market and I’ve used it on several big trips including my 3 months in Asia.

Easy to use

The key to why the compression sac is so useful is because you can vacuum seal literally anything in the bag without needing an actual vacuum.

Once you put in things like clothes into the sac, you seal it up the bag by using the slide zip-lock.

The magic is on the other end of the Pack-It Compression Sac with marked one-way air valves. All you need to do is start from the zippered side of the bag and roll outwards to push air out of the valve.

Once you’re done, your items become completely vacuumed sealed.

That’s it!

When you’d use the compression sac

Here are the best uses of the compression sac when travelling:

  • Compressing bulky gear (i.e. winter jackets and sleeping bags)
  • Using it as an organization tool in combination with other packing cubes
  • When you need waterproofing – A nice side benefit as it keeps water out just as well as it keeps air out
  • Reducing space that clothes takes, allowing you to pack more or open up room.

When you’re not travelling, compression sacs are also useful at home such as when you want to put your puffy down-filled jackets away in the summer.

How effective is the compression

This is space in your suitcase or backpack that you’ll be able to either use to bring more or help you free up room.

Of course, you can’t defy physics which is why the weight will stay the same.

Compact when not in use

You won’t be using the compression sac all the time and so since this is able to be folded and very flat, it’s easy to stuff it in any open spot of your suitcase or backpack.

Areas of improvement

The only issue I’ve had with them so far is that the plastic slider that opens and closes the compression sac comes off easily so you have to be careful with it and be careful not to lose it.

Where to buy

There are 3 different sizes of the Eagle Creek Pack-It Compression Sac you can buy – small, medium, and large. You can buy them individually but also in bundles.

The easiest place to buy the Eagle Creek Pack-It Compression Sac is on Amazon. They offer a bundle with all 3 sizes and another with medium and large.

The Eagle Creek store also has all of the compression sacs in their Compression section where they also carry a bundle with two medium-sized bags.

I’ve also seen it sold online on Moosejaw.

This may not be something you need on every single trip but when you need to lug around bulky items like sleeping bags or you just have a ton of clothes, this is a great way to keep things organized and ultimately reclaim space.

For how useful it is, it’s something that should be part of anyone’s travel kit.

Travel Resources For Your Next Trip

If you’re in the process of planning your trip and putting together your itinerary, these are genuinely the best resources that the Going Awesome Places team stands by 100%.

Credit cards: Don’t get burned by hidden fees on top of terrible exchange rates. When we travel now, we use the Wise Card. Simply load it with the currency you need before you go and use it as a regular VISA or their digital wallet card. Use their free app to track how much you have and top up when you need to.

Flights: Of all the booking search engines, Skyscanner is the most helpful and easy to use thanks to their Everywhere feature. Kayak is also another that’s we will often check as well.

Car Rental: If you’re looking to save money, these car rental coupon codes will be a true game-changer. Otherwise, DiscoverCars and RentalCars are great places to start.

Rideshare: For new Lyft users, use code WILLIAM4825 to get 50% off your first 2 rides (max $10 USD per ride). Offer valid for 14 days after you take your first ride. For new Uber users, use code psuqbjg4d7rn for the same offer except it’s valid for 30 days.

Airport Parking: You’ll need a spot to leave your car at the airport so why not book a spot at a discount. Use code AWESOME7 to get at least $5 off at Airport Parking Reservations or Park Sleep Fly packages.

eSIM: Lately, we’ve really loved using eSIMs. We’ve tested several over the years and we have access to a few special promotions.

  • AmigoSIM – Use GOINGAWESOMEPLACES to save 25% off. Code is re-useable.
  • Gigsky – Use TANG149 to get $3 USD when you sign up, then use code GOINGAWESOME to save 20% on all eSIM orders.
  • KnowRoaming – Use code GAP10 to save 10%.
  • AloSIM – Use code GOINGAWESOMEPLACES to save 15%.
  • Airalo – Use referral code WILLIA9500 to get $3 USD credit on your first purchase.
  • UbigiAWESOME10 to save 10% on your first order.

Wifi Hotspot: We’ve been a huge fan of wifi hotspot devices such as PokeFi (use code GAP24300) because their rates are are hard to beat and it works globally. Solis is another that we recommend. Pros are that you can share the wifi with your whole group but cons are that you have to invest in a device and you have to charge it every night.

Hotels: Our go-to is Booking.com because they have the best inventory of properties including hotels and B&Bs plus they have their Genius tier discounts. Expedia is also worth using especially with their One Key rewards program which is basically like cash. The exception is Asia where Agoda always has the best prices. Always do a quick check on TripAdvisor as well.

Vacation Rentals: Your first instinct will be to check Airbnb but we always recommend checking VRBO as well if you’re looking for a vacation rental (now eligible for One Key).

Tours and Activities: When planning our trips, we always check both Viator and GetYourGuide to at least see what’s out there in the destination that we’re going to. They often have different offerings and prices so check both.

Travel Insurance: Learn how to buy the best travel insurance for you. This isn’t something you want to travel without.

  • HeyMondo – Popular insurance provider for frequent travelers and comes with great coverage and special perks. By booking through our link to get a 15% discount (from June 19-29)!
  • RATESDOTCA – Search engine Canadians looking for the cheapest insurance including multi-trip annual policies.
  • SafetyWing – A perfect fit for long-term nomads.
  • Medjet – Global air medical transportation.

  1. Mari bought me some in Japan…maybe at the 100yen store. I use them sometimes when I’m travelling in the winter. They work best when you are trying to compress fat sweaters!
