10 Best Ventilated Backpacks

10 Best Ventilated Backpacks

Ventilated backpacks, also called suspended-mesh backpacks, keep you cooler and drier when backpacking in hot or humid weather or when you’re carrying a heavy load. First invented by Deuter Packs, they’re one of the most sought-after backpack features by backpackers. While many backpack manufacturers claim that their backpacks are ventilated, it’s important to differentiate between backs with trampoline-style backs that have large air gaps between the mesh and frame to encourage air-flow, and those that have marginally effective “foam air channels.” The performance difference is significant.

Backpack Selection Criteria

These are the most important variables to consider when buying a backpack.

Backpack Sizing

The two most important dimensions for sizing a backpack are your torso length and your hip belt size. Measuring your torso and matching it to pack sizes is pretty straightforward. Measuring the hip belt size you need is a little more obscure because the hip belt specs published by backpack manufacturers have nothing to do with your waist size or hip bone girth. When trying on hip belts, make sure the padded portion of the hip belt covers the front of your hip bones. If it doesn’t, the hip belt is too short and more of the load will rest on your shoulders and less on your hips. If the pack you’re interested in doesn’t have a hip belt that’s large enough to cover your hip bones, do yourself a favor and buy a different backpack.

Backpack Weight

The weights of backpacks can vary widely depending on their volume and feature set. Higher volume, multi-day backpacks over 60 liters generally weigh in at 4-5 pounds, while packs 50 liters and less weigh in at 2-4 pounds. There’s no hard and fast rule that limits acceptable pack weights; just remember that a heavier backpack will be harder and more tiring to carry and let that be your guide.

Backpack Volume

The backpack volume you need will vary depending on the specific gear you need to carry, weather conditions, and the number of days you need to hike between resupply points. Generally speaking, daypacks range from 15-35 liters in size; weekend backpacks range from 30 liters to 50 liters, while multi-day backpacks range from 50-70 liters. Expedition sized packs are much higher volume and can range from 70-110 liters in size.

Backpack Pockets

Most backpacks have a combination of open and closed pockets. Open pockets are useful for storing gear you want fast access to without having to open the main compartment of your backpack. They’re also good for stashing wet gear in order to keep it separate from the dry or delicate gear you store in closed pockets.

Load Lifters

Load lifters are straps attached to a backpack frame, above the shoulder pads, that let you pull the top of the pack forward if you feel it pulling you back onto your heels. They’re a standard feature on high volume backpacks but aren’t as important on smaller volume packs intended to carry lower gear weights.

Ventilated Backpacks

Ventilated backpacks help keep your back and shirt drier by encouraging airflow behind your back and faster evaporation of perspiration. They’re also called suspended mesh backpacks or trampoline backpacks. Largely a comfort feature, they have a minor impact on hiking speed or performance.

Top Closures

Backpacks typically have top lids or roll-top closures to prevent rain from draining into the main compartment. Both closure systems have different merits. Top lids usually have one or two internal pockets that provide additional gear storage for gloves, hats, maps, and navigation equipment. Roll-top closures are simpler and faster to use with fewer straps and provide excellent top compression.

External Attachment Points

Backpacks are designed to carry gear internally and externally, attached to the outside of the backpack. External attachment points or straps are helpful when you need to carry bulky gear that can’t fit inside your backpack like foam sleeping pads, avalanche shovels, skis, snowshoes, or tent bodies.

  1. I’d call the Sierra Designs Flex Capacitor pack a “ventilated pack”, but it does it a different way than these packs. It has stiff foam pads on the shoulder blades and lumbar region, but it doesn’t touch your back at all elsewhere. When there’s a breeze, I can feel it running along my back, which you don’t get with packs that just have small foam channels.

    I’d be interested to hear from someone who has a lot of experience with the Flex Capacitor and one of the trampoline-style packs. I feel like the lack of mesh parkin pressing against your back on the Flex Capacitor is nice, but it does have the three points of contact where there isn’t airflow.

    • You did hear from someone with extensive experience of both packs and pack styles. :-) Me.

      • I’ve read your review of the Flex Capacitor, but it just mentioned the ventilation in passing. I was curious how its ventilation stacks up against these trampoline-style packs. Is its ventilation just a smidge better than “normal” backpacks, or is it nearly as good as trampoline-style backpacks, or something in between?

      • The airflow behind the flex capacitor is better than most packs without a mesh back. Yes definitely. But there are ventilated backpacks where the hip belt is also ventilated. That’s the case with the Gregory Katmai that I have right next to me and is characteristic of many of the anti-gravity ventilated packs out there, Osprey’s being a case in point. They really do help dry your sweat faster than a regular hip belt, like the one on the FC. You don’t sweat less, but you chafe less, if you follow my drift. So to answer you – it’s “in between”. But whether you like ventilated backpacks or not is really down to preference. I care a lot more about the fit, features, and durability of the pack bag than ventilation. But that’s just me.

    • Philip doesn’t just make this stuff up. He reviews these packs the old fashioned way by using them. Check out his Flex Capacitor review. He was one of Skurka’s guides you know.

  2. Thanks Phil, for what you do and sharing it with us.

  3. It seems to me that “ventilated” is just another name for the external frame packs we all grew up with – and there’s nothing wrong with that; the old e-frames were ventilated, too, and carried well. I’ve used the Exos and, for the last couple of years, the Levity and have no complaints. But when I study the pack, I see the same basic structure as my old Camp Trails Adjustable II: a metal perimeter frame with a drum-tight mesh backband. Granted, the frame is no longer made from electrical conduit, with big welds holding the pieces together. Now, the grommets and clevis pins have been replace by wrapping some pack cloth around the arrow-shaft aluminum frames (which mostly hide the frame – to make them look like “internal” frames? But, to me, the high-tech ventilated packs are just an updated version of the old e-frames. Comments?

    • Absolutely although the correlation is harder to see these days. When I first reviewed an exos – 2 or 3 pack generations ago, that was the first thing I thought. Although modern ventilated packs do tend to have a deeper cavity, whereas external frame packs are still shaped by backboards.

  4. I was surprised that the Zpacks Arc Haul didn’t make the list (OK… I’m partial, I’ve been carrying one for 3 years). I have since converted my Arc Haul to use the new fixed arc carbon stays that Zpacks use in the new Arc Air line of packs. I would enjoy reading your review of the newly introduced Zpacks Arc Air 50 and 60 liter packs.

    • Evan Eisentrager

      Dana, what size of the Arc Air stays did you use on your Arc Haul? I tried that too with the medium size stays on my Arc Haul pack, and I think they are a little too short. They keep coming out of the holder pockets. I think the tall size Arc Air stays might be too long, but I don’t know.

      • Evan, I have a short frame Arc Haul. I initially ordered short stays and they were indeed too short. This was before the Arc 60L was introduced. Zpacks replaced the short stays with mediums which I had to trim 1 inch to fit my pack. I also used needle nose pliers inserted into the in the middle stay sleeves to stretch the sleeves ever so slightly to get the new square cross section stays thru. The pack works great with the new fixed arc stays and I have had it on several outing since the mod. While not “officially” supported by Zpacks, they worked with me to make the mod happen. This is my third season with the Arc Haul and it gets used regularly and I am quite happy with it. Even more so now with the fixed arc. I came to the Arc Haul from and Atmos 65 AG (which is quite a nice pack as well) for the substantial pack weight reduction what still retaining an arc design.

      • Evan Eisentrager

        Dana, thanks for this info. I will try to exchange my medium Arc Air stays for the longer Arc Air 60L stays. How hard is to trim these things? It also looks like the stays are slightly pointed up at the ends, which I wonder how hard it would be to duplicate that. I like the way the pack carries better without the mesh, and the new stays feel stronger. I had no trouble getting the new stays through the little loop at the midway point.

      • Evan, I used a dremel rotary tool with an abrasive cut off disk to cut the carbon stays to size (measure twice and cut once). I also used the cut off disk to round the edges of the cut end of the stays. Finally, I coated the cut and rounded ends with a coat of superglue to keep them from delaminating. Make sure you don’t breath the carbon fiber dust when you are cutting.

  5. My osprey EXOS 58 is, aside from being well ventilated, is the most comfortable pack I’ve ever owned and I have owned a Dana Designs Terraplane. (But at 7 lbs. 7oz. it later seemed too heavy even for a winter pack.)

    With my EXOS 58 I ended up cutting off the “pole carriers” and the “speed lid” since I always use the top compartment lid. But… I added Mountain Laurel Designs hybrid Dyneema side pockets

    The Levity 60 seems to be a minimalist EXOS 58. It might be worth it for a thru hike.

    • Eric, the Levity is a completely different pack than the Exos. They feel nothing alike. The Exos carries weight much better and more comfortably (though no hip belt pockets is dumb). The Levity starts losing composure above 25 lbs. For me it just didn’t feel as comfortable as the Exos, or even the REI Flash 55 which is fine with 30 lbs.

  6. Interesting that Osprey reigned over this comparison, but the current Backpacker magazine doesn’t mention a single Osprey model in their latest pack comparison. But REI and Kelty made the grade. I guess Osprey did not reach the proper advertising threshold to get mentioned.
    As always, great article. Planning on buying Exos 58 to replace my AT-worn Atmos. It served me well!

    • Backpacker Magazine….don’t get me started. They’ll take anybody’s money to rank their products.

      There is a reason osprey is the number #1 most popular backpack company in the US and it’s mostly because they sell ventilated packs. Deuter may have invented it, but Osprey owns it.

      • I agree with your assessment of Backpacker Magazine. Just got my last issue on my subscription and have chosen not to renew the subscription for the reason you mentioned. Looked at the Exos models but was puzzled by Ospreys decision to ditch the hip belt pockets. Guess folks are using fanny packs instead. Still have my Atmos AG 65 and agree with your comment about Osprey woning the ventilated design.

      • I think they just got tired of people complaining that the pockets were too small and far back on the hip belt to be of any use.

  7. I have and still use 2015 ArcHaul. I had Zacks upgrade my pack a couple of years ago for $50. They did quite a bit of work on the upgrade. All problems fixed. I am on AT with pack now. Still like the way it rides and the cool breeze on my back

  8. Hey Philip, do you have experience with this version of the North Face Banchee? It seems pretty similar to the Stratos and the Zulu (in the 50L version) and I’m wondering how they compare. Thanks!

    • Not sure I really see the similarities between those. What makes you say that?
      The Banchee has been around forever in the North Face Line. This new revision is pretty nice but doesn’t have the mesh pocket that the zulu has.

      • Well, in terms of features they certainly do have some differences but I see them as the three packs here that fall somewhere between the ultralight packs and the heavier traditional packs both in weight and load capacity. I haven’t been able to find a Stratos or Banchee in person to try out so I could be wrong here.
