Best Ultralight Backpacks

Hardcore ultralight backpacks sacrifice comfort for weight.

Luckily, technological advances have allowed companies to create backpacking packs that are both lightweight AND comfortable.

After all, what’s the point in shedding weight if you cannot fully enjoy your time hiking?

Are you on the lookout for a new ultralight backpack? In general, decent backpacks should last you a good many years–there’s no need to replace them all the time.

But every once in a while–even if it isn’t fatally damaged–it’s a good idea to think about changing your pack.

A backpack that’s on its way to the great outdoor equipment store in the sky will make your life miserable, especially if it wears down over time instead of just falling apart altogether.

If it looks like your pack is heading out the back door, then you’ll want to start keeping your eyes open for good replacements.

Osprey Ultralight Backpack

Fortunately for you, the 2012-2013 season is absolutely phenomenal when it comes to ultralight backpacks. Seriously. I’ve said that every year since 2010, but it only keeps getting better! There are still some winners from 2 years ago that I’ve left on this page, as they are still available to buy and are awesome backpacks.

It seems like every major outdoor gear manufacturer has got a winner coming out this season, but some of them are better than others.

This year it’s no surprise that Osprey, Granite, and GoLite have the best lightweight backpacks on the shelves.

If it’s time to make the trade, or if you’re looking for your first ever backpack, then take a few minutes and see just what makes a good ultralight backpack good, and why the three models listed below take the top prize for ultralight backpacks of the year.

Determining the Best Backpack for Your Hiking Needs

Updated October 2014.

Wanna skip all this and go straight to the reviews? Alright!

Like buying any outdoor equipment, buying a backpack is not something to take lightly. Backpacks (especially ultralight backpacks!) are super expensive and you need to make sure you’re getting the backpack that will suit your needs the best before you lay down hundreds of your hard-earned dollars.

Personally, I spent about 6 months researching, and researching, and researching before finally deciding on buying the Osprey Exos.

And I’ve been backpacking for years now. So, I have a pretty good understanding of the gear, hiker needs etc.

ALSO AWESOME: ULA Equipment Circuit Backpack Video Review

So, like I mentioned, whenever I buy a new piece of outdoor gear, I take loads of time to do all the research:

  • I compare features & figure out which ones are marketing fluff and which are necessary
  • I know how the technical specifications add up
  • And most importantly, I read what people have been saying about it.

These are not impulse buys; they have to be very carefully chosen if you want the most beneficial experience. Especially cause I used to be dirt poor! Buying my Osprey Exos from REI was 2 months of savings that I socked away!

So let’s talk about a few things that you should be thinking about when you’re heading out to buy a new backpack, whether it’s ultralight or not.

Osprey Ultralight Backpack
    • Size vs. Weight— There are two things you can always count on finding: heavy packs with plenty of room and light packs that are tiny. But the real trick is in finding a backpack that is both lightweight and roomy–that’s the good stuff.
    • Storage Options— You want a backpack that not only stores all your camping goods well and tight in the main compartment, but also provides ample storage on the exterior of the pack. With plenty of pockets around the outside, you’ll be able to get access to maps, compasses, snacks, and other goodies without emptying your entire pack.
    • Sleeping Bag Compartment— Some backpacks have sleeping bag compartments. You don’t necessarily need these, but if you’re camping out for multiple nights, you’ll certainly want to think about it. A sleeping bag compartment adds extra weight, so if you aren’t going to be carting around your bag all the time, you may want to think about a pack without one. I personally don’t care for one, but my wife loves hers on her Osprey Aether.
    • Frame or No Frame— If you’re camping for any good length of time or distance, then you’ll want a pack with a frame. A frame will help support the weight you carry and keep you balanced. You can find both external and internal frames, though external frames are getting harder and harder to find as they become more obsolete. You can also find specialized frame-less backpacks that offer necessary support but with a much lighter product weight.
  • Your Gear— Newer backpacks are made for newer gear. With the advancement of manufacturing technologies, outdoor equipment is becoming smaller and lighter… and so are the backpacks. If you have older gear, it might not all fit in a more modern pack. Either choose a pack with a large volume capacity or think about updating your gear.

Naturally, there are some other factors to take into consideration when finding your ultralight backpack–not the least of which is PRICE–but these are the most important. Take care of these, and everything else should fall right into place.

But if you still want a little nudge in the right direction, I’d be happy to oblige. Here’s a look at my top three four for the best ultralight backpacks available in 2012-2013.

Osprey Exos Review

2 years ago I upgraded from a bulky Kelty Coyote pack that weighs upwards of 6 pounds to a lightweight backpack. I had a number of qualifications for my backpack in order for it to meet my needs:

osprey exos ultralight backpack
  • Lightweight – Should be around 2-2.5 pounds
  • Carrying Capacity – I sometimes bring my dSLR camera into the backcountry, so I needed a lightweight backpack that could handle a load of 20-35 pounds
  • Size – I needed a pack that was approximately 3000 cubic inches or 50 liters
  • Accessibility – Top-loading packs may be the lightest of packs, but are a hassle

In the end, I found that the Osprey Exos 58 best met my needs for an ultralight backpack.

Straight up, this pack is amazing. I am a small dude, so the small size fit me and weighs a whopping 2 pounds 8 ounces!!

By using the lightest of all ultralight materials, Osprey created a lightweight backpack that does not skimp on comfort nor handy features for hikers that enjoy a few extra perks. These include:

Wearing my Osprey Exxos, the best lightweight backpack

  • Hipbelt Pockets – Store an energy bar here and access it with ease
  • Ventilated Suspension – Keeps your back cool and dry
  • Trekking Pole Attachment – Stow-on-the-go, as Osprey says. No need to take your pack off when you want to put your trekking poles away
  • Plenty of pockets – Keep your pack organized with 2 front pockets and 2 side mesh pockets – none of this top-loading annoyance

Bottom line is this: I love my Osprey Exos 58.

Osprey Hornet Backpack Review

Surprise, surprise! Here’s Osprey with the #2 spot.

And this may be one of my favorite packs out there. It’s a super light backpack that has amazing versatility, even though a lot of the previous seasons’ special features were removed for this edition.

Osprey Ultralight Backpack

You can find this model in two sizes: 24 and 46 liter. If you have some older equipment, you may want to go with the larger pack. And if you do, don’t worry, it’s still a measly 18 ounces.

Some of the Hornet’s best features include:

  • BioStretch harness
  • ErgoPull cinches
  • Modified frameless design with two Delrin rods for side support
  • And plenty of fantastic storage, both inside and out.

You can find the Osprey Hornet at:

Granite Gear Blaze Backpack Review

This may look like a super simple pack, but don’t be fooled–it’s actually quite sophisticated. Even though my top pick is still the Osprey, the Granite Gear Blaze got the best reviews from consumers who’ve purchased and used it.

This was also a winner of Backpacker’s 2011 Editor’s Choice Award for best-in-class suspension.

A few of this model’s most noteworthy features include:

    • AirCurrent suspension
    • Hydration sleeve
Osprey Ultralight Backpack
  • Lineloc compression cords to keep your gear packed tightly
  • And a super comfy padded hip belt (you don’t normally associate comfy hip belts with ultralight backpacks)

And customers like:

  • Great storage space
  • Rigid but extraordinarily light
  • Incredibly comfortable

And you can find the Granite Gear Blaze Ultralight Backpack at:

GoLite Jam Backpack Review

GoLite Jam 70L
The GoLite Jam 70L Pack is recognized for being a particularly durable lightweight pack thanks to Dyneema® and Ripstop Nylon.

The pack was named Backpacker Magazine’s 2012 Best All-Around Ultralight Pack

Some of its noteworthy features include:

  • Removable foam back pad
  •  Easy to use anchor/strap system that reduces volume
  • Double-Wishbone™ hipbelt with quick-access zippered stretch pockets

Most innovative feature: Pliable backpanel made of high-density closed-cell foam, which offers rigid support, as well as comfort and flex.

Something to keep in mind: GoLite Jam retails for only $129.99. It can be hard to find an award-winning pack that is also one of the most affordable on the market!

Where to buy:


REI Flash: The Cheap, Ultralight Backpack

My final recommendation is the REI Flash.

Personally, for backpacking purposes, this baby just wasn’t for me. We do own the daypack version though and think it rocks!

Here’s why I don’t like it for backpacking: Although it’s ultralight, this pack sacrifices hip comfort. That’s an area that I just would not venture into.

While it is the cheapest of all options and weighs at the very least approximately 2 pounds, an uncomfortable hip belt can ruin a backpacking trip.

Still, it does have benefits, including:

rei flash review
  • Side mesh pockets
  • Removable top pocket to cut down on weight or increase storage capacity
  • Water-resistant
  • Quick storage of trekking poles or ice axes, like the Osprey Exxos

  1. OK so I just found your website and it’s 1st rate! On backpacks….might I suggest this company:
    Eberlestock. Website is listed.
    Two general categories of packs, hunting and tactical. They have videos on just about every one and YouTube also has videos from independent sources. 17 basic designs in “tactical” and 11 in “hunting”.
    I’ll throw this in here……SFO including Navy SEALs get blank checks to procure whatever they feel they need. Your rich Uncle Sam. Many buy these packs! Imagine yourself being trained to survive and have a choice of whatever equipment you want! I’d suggest checking out the website. I’ve used everything from surplus Swiss Army canvas and leather to brand name packs and I don’t know how I managed. Guess I just suffered not knowing how good packs could be. One of these packs will be the ticket for whatever takes you into the wilderness for extended stays. What I really love (since I hunt and don’t have horses or ATVs and honestly wouldn’t use an ATV!!) is that some models are expandable so you can pack out meat plus they have integral rifle scabbards and even a butt bucket for a compound bow. With the integral scabbard you won’t know the extra 9#s of rifle is on your back. Plus, the design allows you to comfortably (or at least manageable) carry much more weight than you could with a lesser pack. I know I’ve packed 75#s 5 miles straight and survived (although a buddy is a chiropractor!) That’s 1/2 my bodyweight. Anyway, check out Eberlestock packs and I think you’ll be amazed at what they offer.

      Hi JT,

      Thanks for your comment.

      While those backpacks seem fantastic for hunting and tactical use, this page is about ultralight backpacks for backpacking. They are completely different beasts.

  2. Daniel Leasure says

    Just found this very good review. I have been on the lightning my load for some time now. My main components remain mostly the same but change do to time I expect to be gone and whether expected. . That said I use 3 different packs the Excos 46ltr cold out or a long trip. Summer spring and fall I will use the Excos 34 ltr and for weekend trips and summer I have gotten to the point of using just the REI FLASH 22 LTR BACKPACK with removed belt and back pad. No need to have that when your pack is a base of 7 lbs. DAN

  3. Jason Lindsay says

    I’m seriously considering downsizing (or down-weighting, perhaps) my pack to the Osprey Exos 58. I have read tons of great things about the features of the pack and I tried one on and liked it. I have not had a chance to field test one, however, and I haven’t found a ton of information regarding it’s comfort while fully loaded on long, multi-day hikes. Can anyone attest to the comfort of this pack after putting some miles on it? It’s pretty much the last thing holding me back from pulling the trigger on this pack. Thanks in advance.

    • Perry Rosenbloom says

      Hi Jason,

      I’ve used the Exos 58 personally for 3 and 5 day backpacking trips. It is very comfortable.

      There is one spot in my lower back that the pack digs into me in an uncomfortable way. However, my body shape is pretty funny so it could be more of an issue wtih me than the pack.



  4. We’ve been looking at Osprey packs for a future JMT section hike of 5-7 days. Do you have any experience of traveling with a bear canister as required on the JMT? We want to keep our weight down especially after being forced to carry canisters, but aren’t sure if the Exos leaves enough room for much else after loading in the bearvault.
