Ultralight Packable Backpacks: Essential Travel Accessories

Sharing is Caring!

I’ve done a lot of things wrong and a few things right in my 18+ years as a career traveler. One of the things I did right was to start traveling with a packable daypack that I could easily pack into my luggage and whip out for various uses at my destination. Ultralight packable backpacks for travel have come a long way since I started out in 2007 and over the years I worked my way through quite a few. 

In this article I’m sharing everything I learned through experience, and and I’ll compare the top packable daypacks on the market, so you can choose the best ultralight backpack for your next trip.

How to Choose the Best Packable Backpack

At a Glance: My Top 4 Picks for Ultralight Packable Daypacks 

Further down, you’ll read a full rundown of each of these packs as well as a bunch more. I have personally used all of these packs and I think they’re terrific. (Buying through these links earns me a small commission; it doesn’t affect your price, and it does help to support this site, so thank you in advance). 

Sea to Summit Ultra-Sil Day Pack – packs down the smallest and is the most lightweight. 

Osprey Ultralight Stuff Pack – same capacity as the pack above but packs down slightly larger; this is because it includes water bottle pockets and more interior organizational features.

Osprey Ultralight DRY Stuff Pack – slightly larger again, but has 2L extra capacity and is waterproof. 

Tortuga Packable Backpack – The least ultralight of these four, but with a structured/padded back and straps that make it the most useful/comfortable as an overall daypack.

Why a Packable Backpack is a Must-Have Travel Accessory

Packable backpacks are lightweight, collapsible bags designed for easy storage and portability. They’re typically made from durable, water-resistant materials that can be folded or rolled into their own pocket or pouch when not in use. 

In addition to their convenience, durable packable daypacks are also an eco-friendly alternative to disposable bags. By using a packable backpack, you can say no to disposable grocery bags (for example), thus reducing waste and promoting sustainability while exploring new destinations.

These backpacks are essential for travel because they take up minimal space in your luggage, and at your destination they’re perfect for a variety of activities from spontaneous day trips or excursions to grocery shopping and more.

Pack More with Less: The Advantages of a Compact Backpack

In my opinion, no packing list is complete without a lightweight packable daypack. From convenience to versatility, ultralight travel backpacks are the ultimate travel companion for adventure seekers and globe-trotters alike.

Here’s why: 

Packs Into its Own Pocket

One of the most remarkable features of a ultralight travel backpack is its ability to pack into its own pocket. This is not only instrumental for travel packing, but also at your destination. It’s easy to pop a packable backpack into a small purse or bag while you’re out, and then if you find yourself buying something and you need the extra space, you’ve got your pack ready and you can skip the disposable bags!

Ease of Packing (Into Luggage)

You’re not likely going to want to use a packable daypack on travel days; for protecting/organizing/transporting your beloved belongings, you’ll want a travel backpack a bit better designed for the task. 

So the more compact a packable travel backpack can be, the easier it is to fit into your suitcase, which is especially important if you like to travel with carry-on luggage only.

Multiple Uses 

The number of things you can use ultralight packable daypacks for are limited only by your imagination. You can take them on hiking adventures, overnight trips, to the co-working space, grocery shopping, day-trip excursions, and more. No matter the situation, an ultralight packable daypack is a versatile and reliable choice.

Convenience & Portability

Because they pack down so small, you can take your packable backpack anywhere – which means it will always be ready when you need it. 

Great for Travel with Carry-on Only

If you prefer to travel light and avoid checking luggage, ultralight packable backpacks are downright essential. They’re lightweight and compact enough to fit in your carry-on, so you have a reliable bag with you at your destination. 

Just recently I was on a “one bag travel” trip (which means I traveled with one carry-on bag only, instead of the usual carry-on entourage which includes a carry-on suitcase plus a personal item). Not only was my packable backpack invaluable at my destination for outings and excursions, but even on my travel day it saved my skin! 

I was flying on a small plane, and because the overhead bins were tiny, they were gate-checking all carry-on backpacks and suitcases. Luckily I pulled out my packable backpack and loaded it up with valuables and fragile items like my laptop, electronics, medications, etc to take on board with me while my carry on backpack got loaded into the cargo hold. 

I’m not sure what I would have done without my packable backpack. 

Find Your Perfect Adventure Companion: Tips for Choosing a Packable Daypack

Everybody’s criteria for the perfect portable daypack will differ. Here are some essential features to consider when selecting a travel daypack, so you can find the best one for your needs. 

Before you even look at the specific features, consider the nature of your trip and how you might use your pack at your destination. Are you going to be doing outdoorsy stuff like day hikes, or perhaps even taking it on multi-day excursions? Or are you an urban warrior or remote worker who will want to use it to take your laptop and essentials to the co-working space? Or maybe you want your packable backpack to help you do both? 

With this in mind, consider the features below and which will be most important to you. 

Size and Capacity

The goal when considering size and capacity, is to hit that sweet spot between the smallest possible size when packed down, and the largest possible capacity when being used as a backpack. But the reality is, the larger the capacity of the bag, the larger it will be when packed down as well – which might be an important factor if your luggage is already full. 

In the breakdown of packable backpacks below, keep an eye on the weight, because that will give you an indication of how bulky it will be when it’s packed down, since most companies don’t actually give the dimensions of their bags when packed into their pouches or pockets.  

Material and Weight

When it comes to material and weight, there’s a balance between durability and packability. The more durable or waterproof the material is, the heavier it will be and/or the bulkier it will be when packed down (ie: the more luggage space it will take up). 

The more features it has like extra pockets or reinforced shoulder straps, the more useful it might be for heavier loads, but again, the less packable it will be. 

Here are some common materials used to make packable backpacks: 

30D siliconized CORDURA® is a lightweight, durable, and water-resistant material that offers excellent tear resistance. The siliconized treatment makes it ideal for use in harsh or wet environments, although it may be less breathable than other fabrics.

40D Nylon Ripstop is a robust and lightweight fabric that features excellent tear and abrasion resistance. The ripstop weave prevents tears from spreading, making it a great choice if you’re an active traveler and/or you like to abuse your stuff. However, it may not provide the same level of water resistance as siliconized CORDURA®.

The “D” in 30D and 40D refers to the fabric’s denier, which is a unit of measurement for the linear mass density of fibres. A higher denier indicates a thicker, more durable fabric, while a lower denier suggests a lighter, more breathable material. In this context, 40D Nylon Ripstop is thicker and more durable than 30D siliconized CORDURA® but may be slightly heavier.

Additional Features and Accessories

It’s the features and accessories of your ultralight daypack that can make or break your experience. Some examples of additional features and accessories to look for include:

Water bottle pockets: Daypacks with dedicated water bottle pockets provide the convenience of carrying your water bottle securely, ensuring easy access when needed. The extra material of the pocket adds to the overall bulk of the pack, but is immeasurably handier than having to keep your water bottle in the main compartment which isn’t as accessible. Also a lack of water bottle pockets eats into the capacity of the bag itself, which may be important.

Interior pockets for organization: Keeping your belongings organized is crucial, especially on-the-go. Interior pockets offer designated spaces for your valuables, electronics, and smaller items, allowing you to locate them quickly and prevent them from getting lost or damaged.

Compression straps: Compression straps found on the exterior of daypacks help reduce bulk and secure your gear. By tightening these straps, you can maintain a compact profile, which is particularly useful when navigating through crowds or trying to fit your daypack into tight spaces.

Exterior loops for gear attachment: If you need to carry extra equipment or accessories, exterior loops offer a handy way to attach items using a carabiner. These loops allow you to attach items such as umbrellas, walking poles, or even a jacket to the outside of your daypack, freeing up valuable interior space.

Waterproof materials and construction: You never know when the skies will open up. Waterproof materials and construction protect your belongings from getting wet, ensuring your gear stays safe from potential damage. However most waterproof packs will also be a bit bulkier and heavier.

Final Thoughts and Recommendations: The Best Ultralight Packable Backpacks for Travel

I personally own a few of these packs; specifically the Osprey packs (both of them), the Sea to Summit Ultra-Sil Day Pack, and the Tortuga Packable Backpack. I wanted to include some others in this article to make this a comprehensive review, but to be honest, in my opinion none of them measure up. (The only other one I would consider would be the Sea to Summit Ultra Sil Dry Day Pack for its ultralight qualities, though I don’t like that it doesn’t have any extra pockets). 

The Matador pack might be an option if I required a super heavy-duty pack for a technical excursion, but it comes at a pretty heavy (literally) price of weight and bulk. 

But in the end it boils down to you and what you need in a packable backpack. For me, it needs to be ultralight, pack down super small, and be multi-functional for a variety of uses on the road. Your needs may be different.

13 thoughts on “Ultralight Packable Backpacks: Essential Travel Accessories”

  1. I’m fascinated by the ability to pack a lightweight backpack it in its own pocket. That has never crossed my mind before, and that feature alone makes me want to go grab myself one of these remarkable bags. Not only does it give you extra space at your destination as you rightly explained, I also like that it does away with the need to use disposable bags which is good for the environment.

    Do you have a favorite among these recommendations Nora?


    • Hi Femi,
      My two favs are the Sea to Summit (because it’s the smallest and lightest of them all), and the Osprey (because they’re only a weeeee bit bigger/heavier but include some vital organizational components that make it a more well-rounded bag).

      • Great choices Nora – You can always rely on Osprey to exceed expectations for the most part. And Sea to Summit is a decent brand – they do great sleeping bags. Of the two, I’m leaning towards Sea to Summit just because I already have an Osprey backpack, and I’d like to try something different:)

  2. I really enjoyed your blog post on ultralight packable backpacks. I’ve been traveling for many years, and I’ve always found that a good packable backpack is an essential travel accessory. It’s so convenient to have a small, lightweight backpack that you can pack into your luggage and then use for day trips, excursions, or even just carrying your essentials around town.

    I’ve used a few different packable backpacks over the years, and I’ve found that the best ones are lightweight, durable, and have a few extra features like water bottle pockets and padded laptop compartments. I’m currently using the Eagle Creek Packable Backpack and I’m really happy with it. It’s small enough to fit in my carry-on luggage, but it’s big enough to fit everything I need for a day trip. It’s also made of durable materials that can withstand some wear and tear.

  3. Nora, could you please do a review on best lightweight but sturdy checked in bags/duffels and vacuums bags for packing clothing/bulky compressible things.

  4. Hi,

    Do you have any recommendations for a lightweight, packable sling style day pack?

    I prefer something that can be worn in front, is big enough to stuff a jacket or coat in, has a pocket for a 2 in 1 tablet computer and secure interior pockets for phone, money, keys etc. Plus room for all the other stuff one carries around.


  5. I used the Peak Gear foldable backpack during the last month traveling around France and England. It’s around 20L (16x12x6in) and weighs 7.65 oz (217g). Unlike the lighter packs on your list, it doesn’t get wrinkley and it’s comfortable for the whole day. It has 2 water bottle pockets so I used the second one for my sunglasses case or my umbrella, depending on the weather. It’s strong enough for a bottle of wine and groceries in addition to whatever else I was carrying. I think it looks nicer than the ones by backpacking/hiking companies and didn’t make me feel like I stood out in Paris or London. There is an internal pocket meant for a laptop or folders, but I found that by placing my wallet in that pocket, it was pretty much invisible when I opened the backpack, so that felt more secure.

    In addition to being my day pack for adventures, it was a lifesaver for carrying my groceries and other purchases from town to town on trains and buses. I ended up checking my carry on bag when I returned home and it was perfect to use as my personal item for a few extra items I picked up along the way. I will be using this around town now that I’m home and not reserving it for travel.

  6. For the one-bag travel scenario,
    Instead of packing your “packable” backpack empty, use it like a packing cube in your carry-on. Pack it with the stuff you absolutely do not want to chance losing and what you would need to survive if the rest of your stuff didn’t make the trip. That way if you suddenly find yourself in a gate-check situation, you just open your carry-on, retrieve your pre-packed backpack and you’re good to go. No scrambling to make sure you have your toothbrush, change of underwear, meds, electronics, etc.

    • Hi K,
      Fantastic tip for one bag travel! I have run into this exact challenge; traveling with one bag that had to be checked. Luckily I had my packable backpack and I took out the things I needed to carry on the plane with me. I didn’t have it all pre-packed though.
