DSCF4301I really want to hate this bag. After all it weighs 1kilo, holds just 50 liters and is mass produced in vietnam with second tier textiles (compared to cuben fiber). But I also want to give this bag an honest shot – I paid just 100usd for it on sale and compared to many other backpacks that can be bought in regular outdoor shops; this bag is light. So here I am a couple of weeks later and 100 kilometers on my back with it and I don’t want to give it back. It’s a love hate relationship here: It’s heavier and smaller than my zpacks arc-blast, it’s arguably uglier, and because I really want to hate it I really searched for all the problems I could.

The truth is though, that vietnamese children really know how to sew..  Ok, I take that back, I actually have no idea at all if there are actual children working 7 days a week 16 hour shifts, eating left over textiles in some kind of soup concoction to survive..  I’m sure these are well trained, educated, well paid adults that work under excellent conditions. It’s just my bias towards outsourcing production to cheap labour countries that has a habit of forming opinions for me.

Anyway, as I said the Vietnamese really know how to sew – the Osprey EXOS 48 is an excellent lightweight bag that I think would fit most lightweight hikers quite well. For the price I can definitely recommend for anyone to try it – also Osprey has at least in the past been well known for their excellent working conditions and social  awareness. I’m sure they still are even if production has moved.


I will start with my gripes first as I really wanted to hate this bag:

The frame is not adjustable
 – I know for a lot of people this is a ridiculous assumption, but I am used to the Arc-blast where I can actually make the frame tighter or looser against my back. The actual bow-ness in the frame. I would like to have the frame just a tad bit closer to my back so that the balance is a little better.

The mesh side pockets – were obviously designed by 10 year old vietnamese kids that have tiny bendable arms that can without a problem snake their arms around their bodies and reach down into this tiny little pocket to get the water bottle or anything else a kid might put in there. As for adults, well we would have to take the pack off, have it either hang on one shoulder or put it on the ground, open up the tight little pocket with one hand and insert or remove so called water bottle with the other. I use just a small lightweight PET coke bottle as my water bottle – imagine trying to do this with a massive Nalgene bottle. Granted, at least the made mesh pockets – some companies don’t even bother with this awesome feature.


Two lids – Why? I think one lid would have been sufficient here: maybe it’s me that doesn’t get it? Maybe one of the lids can by detached and used as a front pouch? It’s not very obvious anyway.

It’s heavy for a 51 liter bag – At 1 kilo this bag weighs 400 grams more than my Arc-blast and carries 10 liters less. Again, I really am looking for reasons to hate this bag.

Hip belt pockets suck – Perfect for little vietnamese fingers and toys, but for any real usage they should have just left them off and sold bigger add on pouches or something. I think my side pouch can hold a cliff bar, maybe a snickers in there as well or two of these tiny kex bars.


That’s it – that’s all I can bitch about on a bag that I really wanted to hate. I used it on a three day hike here in Sweden and found it big enough for all my gear and three days of food and goodies

So what’s good about this bag?

Excellent carrying capabilities – My total pack weighed roughly 7 kilos at the start. It was more comfortable than with my Arc-blast. I hate saying that, it hurts admitting that. It sat on my hips beautifully and my back was nice and aired out the entire time. Most of the time I didn’t even think about the pack being there. It really is a wonderment of craftsmanship how well this bag sits on my body.

Good design – This bag though made for tiny hands and fingers is an excellently designed and functional pack for what it does. A few gripes with the water bottle being a bitch to take out, and it can always have more entries and zippers into the pack (just about any pack could)

It is half the weight of similar bags – I bitch about it being heavier than my Arc-blast, but go into any store and you will be hard pressed to find a lighter weight bag with the same carrying capacity, features, functions and above all price.

In conclusion: 

How can I not recommend this bag? Hiking in it has been a dream – it sits so well on my body that it disgusts me. I think this is a great pack for most lightweight hikers for up to a week of hiking. The side pockets and hip-pockets could be much better, the frame could be adjustable and these packs could still be made in the USA. But then they probably wouldn’t cost 100usd and be available at your local gear shop. Also, I am a bit of a hypocrite as I love almost the entire Haglöfs LIM gear series – who do you think makes those?

If you see this in the shop feel free to try it on – just be warned, when you put it on your back, you will be 150usd poorer.

  1. First of all great site!! The backpack is that good and even better, I just hiked 2000km with this baby and enjoyed every second.

    Even your negatives were no problem for me, I loved the side pockets for easy use. Im not sure how you took the picture, but my 75cl bottle fitted easily in each side pocket.

    Front pockets also great size in my opinion, could store my camera, batteries, money, cards, some food and more in both.

    Keep up the good work!


    1. Thanks for your response! I’m glad the pockets worked for you! Like I said I found them a bit wanting, but as long as they work go for it 🙂


  2. Thanks for this review. I have this pack, and was struggling with the large water bottle pockets (could not put my water bottle back in without taking pack off). BUT – from your picture, I see you’ve put the bottle in the smaller pocket closer to your back – so I’m trying this out. I didn’t even think of that! Thank you!!


  3. Well….ummm…I consider myself a “superlight” backpacker, definitely well above “ultra” but probably below “light” and I normally use an Osprey 33 liter Talon for up to about a week, and that’s with a winter sleeping bag…so I have immediately lost interest in you and your blog if you use something 50% bigger than I do. What kind of crap do you haul?? Do I dare look at your website more now?

    I can only hope this is your 10-15 day backpack, at the least….I mean, 48 liters is just huge like I used to use in the dinosaur days.

    If I was going summer hiking with a summer sleeping back, I’d be down to 25 liters or less for 5 or 6 days. what do you haul around, exactly?


    1. Hi Korlang and thanks for the comment! That’s awesome that SUL works for you, it just doesn’t work for me. I just wrote a post called “is ultralight right for you” and there I describe a little more in detail my ultraligth/lightweight setup.. I hope you find something on this site of use none-the-less. Good luck!


      1. Ummm…Superlight is actually heavier than Ultralight, isn’t it? I keep it around 8- 10 pounds (not including water) for 2 or 3 night trips (3-season), adding about a pound of food weight for each additional night on average. I don’t believe that is Ultralight…I don’t sew my own gear, and I have a regular backpack and sleeping bag, not a frameless sub-one-pound backpack nor a 18 ounce quilt. I know that I could go substantially lighter if I invested money and some labor into it….but by not bringing a tent or cooking gear or much else, i’m still very light.

      2. i realize that my comment above was very elitist and could be seen as harshly worded, so sorry. i think the name of your blog confused me…frankly i have no idea what “ultralight” means but it clearly sounds more extreme (in English at least) than it must mean. in my mind when i wrote that comment i just couldn’t reconcile “ultralight” with “50 liters” but now I can see that ultralight is the new “normal”…

        again, sorry. take care and keep up the good work.

  4. One pound of food a day? How is that even possible unless you are losing weight, eating pure sugar, or drinking oil.


    1. Hi Tom,
      Thanks for the question! it’s perfectly possible, and your questions inspires me to do a packing list for food and menu items. Hopefully I will have the post done within the week.

      Anyway, I’m not sure how you pack food but I always dehydrate my food. for example 1 dl of oats for breakfast dried of course weighs just 100grams. When hydrated it gives about 200grams of food and I find this adequate for my breakfast. For my lunch (If I bring lunch) I pack around 150grams dehydrated usually of high energy meals (brown rice with vegetables and so on). Even dried mash potatoes gives incredible energy for the weight. With my breakfast lunch and dinner weighing in at 450grams to 500grams the rest then is candy bars and so on.. maybe 100-200grams depending on were and how long I will be hiking for. Some people skip out and lunch and fill it with candy instead.

      In anycase, I usually count on about 500-700grams per day in food and snacks and portion out my rations accordingly.

      hope this helps!



      1. 500-700 grams is more than a pound and makes more sense to me. I’m usually at 700-800 grams a day. Unfortunately for me, I don’t eat sugar or grains which poses some challenges when planning my meals.

    2. Sugar has much less calories by weight (roughly 1/2) then food high in protein and fat such as nuts, nut butters, sardines or kipper snacks, (70%+ cacao) chocolate, dried fish or meat (jerky or similar), hard cheeses, salami or summer sausage that doesn’t need refridgeration, and so on. One pound of most of these types of foods is roughly enough for a day. Yes, you might lose a little body weight by the end of a 5+ day trip, but (at least for me) that’s not a bad thing. Honestly I usually end up bringing some heavier perishable stuff that I will eat in the first day or two, such as a couple of bagels, maybe an avocado, a couple sushi rolls, an apple, or whatever… In my experience, often the first day out is the “approach day” getting just from the trailhead into the wilderness, and also a short day from either starting late or whatever, so i often start with about 4 pounds of expendibles that won’t last long…hell, even a bottle of wine for the first night! 😉 But when the trail gets steeper, the oxygen thinner, and the days longer, I don’t want to be hauling anything extraneous, and a 4 ounces of almonds with a cup of green tea is a fine lunch for me and my body.
