5 Best Ultralight Backpacks for Long Distance Backpacking

A lot of hikers ask me which backpacks I think are the best for multi-day hikes and long distance backpacking, and time and again, I recommend the packs listed below. Why? I think they’re large enough to fit all of the gear and food you need for a backpacking trip for a variety of temperatures and terrain, they all carry extremely well, and their internal and external storage is simple and functional. While these are all great packs, they all have slightly different personalities, with slightly different strengths and weaknesses, which I spell out below.

1. Gossamer Gear Mariposa 60 Backpack

The Gossamer Gear Mariposa is a great pack for backpackers who are still lightening their loads because it has plenty of storage. As someone who’s taken a Mariposa on most of my long hikes ranging from 50 up to 250 miles, I can tell you it’s intuitively organized for a multi-day trip, with plenty of external pockets for wet or bulky gear, and lots of covered storage for items you need less frequent access too. It also has a unique long side pocket that’s perfect for storing a tent, especially a wet tent, separate from the rest of your gear. The Mariposa is a very refined and comfortable ultralight pack, best used for hiking on established trails.

2. Hyperlite Mountain Gear 3400 Southwest Pack

Hyperlite Mountain Gear specializes in multi-sport backpacks for backpacking, climbing, packrafting, and winter sports where durability, a streamlined exterior, and enhanced waterproofing are important. While their packs are made using cuben fiber which is tough and lightweight, they tend to use a heavier grade of fabric than other gear makers, emphasizing durability over weight. If you backpack off the beaten track, off-trail, or in conditions that will rip the heck out of a nylon backpack, I recommend you get the Hyperlite Mountain Gear 3400 Southwest Pack. 

Don’t need as much storage capacity? Try the 2400 Southwest Pack.

3. Ultralight Adventure Equipment Circuit Backpack

The Circuit is a tough ultralight pack with a tear drop shape that results in an excellent carry. While it is the heaviest ultralight backpack I recommend, I like it because it’s tough enough and functional enough for 4 season use, with an excellent external attachment system for carrying winter gear. I also like the Circuit because it’s one of the friendlier packs available for women, with a choice of shoulder straps to fit the female figure. Fit is the most important aspect of buying any backpack and the folks at ULA are borderline fanatical about making sure their customers’ packs fit them perfectly. So if you’re looking for a company with high touch customer service, they’re a good choice.

  • Replaceable hip belt, with multiple sizes available for a custom fit
  • Multiple shoulder strap options available, enabling unisex wear


  • Heavier than other alternatives

4. Zpacks.com Arc Blast Backpack

The Zpacks.com Arc Blast is a cuben fiber backpack with an adjustable length backpack making it a good choice for backpackers who want to dial in a custom fit. The Arc Blast also has a mesh back panel that provides better back ventilation in hot and humid weather since it has a trampoline style external frame While the Arc Blast is durable enough for hiking on trails, the external frame, rear mesh pocket, and external attachment straps make it too fragile vulnerable for off-trail hiking. Still, it’s an excellent pack for long trail hiking with a great carry and a highly functional assortment of pockets and external attachment options.

Don’t need as much storage? The Arc Blast is also available in a 52 liter and 45 liter size.

5. Granite Gear Crown VC 60

The Granite Gear Crown VC 60 is the only ultralight backpack that I recommend that you can try on at REI and other outdoor retailers. It’s also the least expensive one. Available in both a men’s and women’s version, the Crown is laid out like other ultralight backpacks with a long rear mesh pocket, side water bottle pockets, and a roll top closure. The distinguishing feature of the Crown is its 360 degree compression system which along the top, back, and sides of the pack, which is better than any of the other packs I’ve listed above. This is an important capability if you take a lot of trips with very different capacity requirements – long trips with a lot of gear and supplies, or shorter trips with far less – making it an excellent pack for thru-hikes as well. With mesh pockets, I wouldn’t recommend taking the Crown off-trail, but it’s an excellent pack for hiking on established trails with a really good carry.

  1. I haven’t been on a real hike since I was a teen, about two weeks in the mountains of Wyoming, and I’m attempting to get myself highly encouraged to attempt the Thru-hike of the Appalachian Trail, what pack would you recommend? I understand you only need minimal supplies and should be as light as possible, plus you can resupply throughout the trek.

  2. Actually the ULA CDT is a better choice in my opinion. It’s lighter and has 50 liter storage. I’m sure the circuit is nice too, but you can shave nearly 20 ounces with the CDT. I’ve used it for a couple of years now and I love it. I usually use a tent vertically in the center of the main compartment to give it structure since it has no frame. I’ve found it comfortable up to around 25-30 lbs.

  3. As an avid offroad camper but a total newbie to backpacking, I really appreciate these reviews. I am a small-ish woman looking for comfortable ultralight gear, however I’ve found relatively few female specific ultralight backpacks to choose from. Many unisex, but not many geared at women specifically. Seems like there are more ‘traditional’ women’s packs (heavy). I’m very interested in the Zpacks. Have any ladies out there had any experience with the Zpacks?

  4. You reviewed ZPacks Arc Blast but Zpacks Arc Haul is very similar and this is my experience June 2016. This style is stated to have a 40lbs load capacity. I took it for 35 miles in three days holding 33lbs to test it for when I go for a few months into nomads land. On day ONE I felt a rash forming on my lower back. All the weight was pushing down resting on the center of my lower back and I tried everything to get it to my waist….and YES…I know how to pack and dress. Upon my return I had a rash the full length of where the belt is sewn into the backpack. In another day or two it would have been raw. I’d even changed clothes. Another site also tested the style you reviewed stating it should carry 12lbs less than what Zpacks states. So…I’m not alone. Basically – I feel their load capacity is for the strength of the bag but not what happens when carried on a human being. The belt is a weak design for heavy loads and is hollowed on the inside…ya…beats me! Also…the carbon rods running vertical along the sides for support cause a sharp razor-like edge at the bottom…which sliced my thigh when resting it and then bringing it around to my back. Another bad design overlook. Unfortunately I didn’t hike within 30 days of receiving my pack because it was winter for me…so…I’m limited to a store credit which does nothing for me since I don’t want anything else from Zpacks. When you get the pack be sure to load it up to near capacity and go for a 10hr hike…ups and downs…etc..and see how it feels but be sure it’s within 30days of getting it if you need to return for a full refund. Also, side pockets cost extra and it takes 6 weeks to get. I think Joe has some great designs but safety and belt capacity on a human still need work.

  5. I see that you considered the Osprey Exos 58, and I’m just wondering what it was about it that didn’t make it a Top 5 contender? I just went on a week long trip in the Rockies and 4 of my friends have this pack and love it. I’ve really been considering it, but interested in what your thoughts on it are.

    • The Hip belt sizing of the Exos is its downfall. If it fits you great, but Osprey seemingly goes out of its way to sell you a pack where it’s very difficult to get a proper fit because the hip belt is too short. Which is one of them aim reasons it’s not in the top 5. You can read my review here. packs

  6. Philip,
    I was interested in replacing my LLBean White Mountain pack. At over 6 pounds, I was looking to downsize to complete my section hiking of the Long Trail. While comfortable, durable, and set up well, it seemed like a good idea to replace it.
    I read this article, then went to Outdoor Gear Exchange in Burlington. An experienced AT hiker worked there, and after trying several packs, he said to try the VC60. It fit well, so I bought it. While it didn’t have the compartments of my Bean pack, I found that I had to re-learn my arrangement of stuff.
    I did Section 10 using this and it worked pretty well, though still working on how my stuff is arranged. I am a slow hiker at my age, so take a bit more time when I do my hikes.
    Bottom line in the Crown VC 60: I like it.

  7. Fellow hikers;
    Over the years from 1968 to the present I hiked with backpacks made by Kelty, Gregory, Lowe Pro, Dana Designs, Ems and until recently, my very favorite,the Osprey Aether 85. I never thought I would stop using the Osprey but decided at my age of mid 70’s to try a light weight back pack. After some research I purchased the ULA “Circuit”. This pack is just right for me at my current age of 78. Note: If I was younger I would still be with the Osprey as it was the most comfortable for carrying about 35 pounds and fit me perfectly. Now with the Circuit my loads are about 30 pounds as I do not hike as far and my equipment is all the best lightweight gear I can find. For example, I really love my Zpacks raincoat, my 25 degree Feathered friends bag that weights in about 28 oz, My platypus gravity water system (Note: I am now trying out the Sawyer Mini water system and so far like it. I have noticed that most thru hikers are using the Sawyer). With the Platypus gravity system I always carried a plastic cup for when the water availability was limited and this enabled me to easily fill the “dirty” bladder. My other light weight gear includes; GSI Pinnalcle Soloist cook kit, Pocket Rocket stove, Nemo Cosmo sleeping pad, and Big Agnus Fly creek 2 Platinum tent. I am still able to do a 10 mile hike although it is noticeably more difficult. As the saying goes, my mind says I can do it but my body is not really fully convinced!!! I hope all reading this stay on the trails for as long as I have. It gets in your blood and perhaps that is where I will end up at the end of my days. Happy hiking.
