Whichever manner you select to go, Osprey and Zpacks are nonetheless the one pack producers to supply ultralight, ventilated, and adjustable-length backpacks.

Backpack Organization and Storage

The Osprey Exos Pro 55 could be very completely different from most ultralight backpacks as a result of it’s configured with a floating prime lid as a substitute of a dry-bag model roll prime. With a single giant prime zippered pocket (with key fob), the floating lid allows you to sandwich further gear between the lid and the highest of the pack’s fundamental compartment so you’ll be able to carry further technical gear or provides that gained’t match inside your pack. Top lids are an ideal function, particularly when you should carry cumbersome gear like bear canisters, rope coils, foam pads, or tent our bodies that gained’t match into the principle compartment of your pack. The prime pocket additionally offers useful entry to hats, gloves, snacks, and navigation gear and is indispensable for cold-weather use.

If you don’t want the highest lid on the Exos Pro 55, you’ll be able to take away it to avoid wasting gear weight. This reduces the load of a small/medium Exos Pro 55 by 2.6 ounces bringing it all the way down to a good 30.6 oz (1 lb 14.6 oz).

There’s a nylon flap underneath the highest lid that’s completely hooked up to the pack, what Osprey calls a FlapJacket, that covers the drawstring opening of the principle compartment. When you take away the highest lid, the FlapJacket is used to guard the principle compartment from the rain in its stead. The rear of the FlapJacket clips into the identical rear straps and buckles utilized by the highest lid so that you’re not left with any further straps or buckles to get in the best way. When it’s not wanted you’ll be able to stuff it into the principle compartment or into the inner hydration pocket.

While the Exos Pro 55 additionally has good open storage within the type of facet and entrance pockets, the principle compartment is the place the majority of this pack’s capability is. With over 3350 cubic inches of room, you’ll be able to put a ton of substances and meals inside. Being a mainstream backpack producer, Osprey computes the amount of their packs utilizing trade norms and solely counts coated and zippered storage once they calculate backpack quantity. If you’re evaluating the amount of the Exos Pro 55 with a pack from a cottage backpack maker, bear in mind that they typically add in open and closed pocket volumes so the Exos Pro 55 will really feel fairly a bit bigger and maintain significantly extra gear.

While the principle compartment curves inward to accommodate the form of the ventilated body close to its base, the principle compartment is so giant that the pack remains to be simple to pack. Still, as a result of it’s ventilated, you’ll need to place the heaviest objects as near your again and hips as doable. With the exception of a hydration pocket, dangle loop, and prime compression strap, there’s nothing contained in the Exos Pro 55 fundamental compartment like a sleeping bag compartment to interrupt up the seemingly cavernous area. Still, it’s simple to see inside the principle compartment as a result of frivolously coloured cloth panels assist channel gentle to the pack’s inside. I’d nonetheless advocate packing the Exos Pro 55 with a pack liner for moisture/rain safety (See Five Ultralight Pack Liners Compared.)

Osprey included hipbelt pockets on the Exos Pro 55 however they’re barely completely different than these on the present Exos 58. The left-hand pocket is now open on prime and doesn’t have a zipper. I believed I’d hate that, but it surely’s truly fairly helpful for stuffing trash into. The right-hand pocket remains to be zippered and enormous sufficient to suit an iPhone X into together with some snack bars.

But the pockets are sewn onto the hipbelt in such a manner that the again of the pocket has to have the ability to curve when it wraps round your hips…which is an efficient strategy to break a SmartPhone display. I’d advise towards placing something equally outsized and rigid into them.

This is the results of the truth that Osprey retains the hipbelt wings on the Exos Pro 55 and Exos 58 brief, in order that they wrap across the again and sides of your iliac crest (hipbone) however don’t lengthen extra ahead to the entrance like different backpacks. They nonetheless present efficient load-to-hip weight switch, however I personally desire longer hipbelts as a result of it means the hipbelt pockets are positioned in entrance of my torso and never alongside the edges or again of my hips. You do get used to the shorter hipbelt rapidly on the Exos Pro 55 and Exos 58, however it’s a completely different strategy to hipbelt size and pocket placement than on backpacks from different producers.

In addition to the principle compartment, the Exos Pro 55 has two stretch-side mesh pockets that can be utilized to retailer water bottles. The mesh shouldn’t be sturdy sufficient for off-trail journey and I might advocate you keep on trails with this pack in an effort to maintain the pockets from tearing. Each pocket is strengthened with strong cloth on the underside for higher sturdiness and has a holster-style opening minimize in entrance, which helps you to place bottles sideways so you’ll be able to pull them out and exchange them when on the transfer.

You may pack a tall bottle and screwed-on filter within the facet pockets, however they aren’t reachable when carrying the pack and tall bottles fall out of the holster pockets when you attempt to relaxation them there.

There can also be a big stretch stuff-it pocket on the entrance of the pack which is beneficial for carrying objects that you really want quick access to, with out requiring that you simply cease and open your backpack. I can’t reside with out a stretch pocket like this and use it to stuff gentle layers or snacks that I would like simply accessible through the day. It’s additionally a superb place to stash a moist rainfly, so you’ll be able to simply pull it out to dry if you cease to admire a view.

Backpack Frame and Suspension

The Osprey Exos Pro 55 is a ventilated suspended mesh-style backpack. Breathable mesh is suspended in entrance of the again panel making a ventilated area behind your again that’s designed to evaporate sweat earlier than it may soak your shirt. The mesh is tightly stretched throughout the 360-degree aluminum body which additionally serves to anchor the hip belt and cargo lifters. The aluminum body on the Exos Pro 55 is the key sauce that “makes” this pack. It’s tremendous light-weight and stiff, offering nice load switch to the hips, so you’ll be able to load up this pack and nonetheless get a really comfy carry. The carry is definitely fairly superb, even with a full load.

This new Exos Pro 55 additionally has an adjustable torso size with 4″ of adjustability that could be very light-weight and easy to make use of. This is a big profit for brand spanking new backpackers who’ve much less expertise sizing and becoming a brand new backpack. You lengthen or shorten the torso size, the space between your hip bones and your C7 vertebra, by transferring the shoulder strap harness up or down because the place of the hip belt is fastened. This is completed utilizing a easy dowel and ladder system which slides up and down alongside the observe on the again of the backpack.

The shoulder straps and hipbelt are each coated with a stretchy mesh cloth that’s comfortable and helps wick moisture to forestall rubbing and chafing. The shoulder straps are frivolously padded and have one elastic hydration hose keeper strap on the entrance. However, whereas the shoulder straps are comfy, you’ll be considerably challenged to connect accent pockets to them, one thing that’s more and more fashionable with backpackers and day hikers alike. The similar will be mentioned for the frivolously padded hip belt.

Unlike the Exos 58, the sternum strap on the Exos Pro 55 can solely be positioned at three areas. To regulate it, you should push the plastic buckles connecting the sternum strap to the shoulder straps by means of small wire loops to reposition them greater or decrease. It takes a bit endurance to do that but it surely’s not troublesome and makes for a really safe anchor.

Sizing

The Exos Pro 55 is available in two sizes S/M and L/XL by way of torso size, whereas the hip belt size is sort of an identical throughout each sizes (28″-50″ vs 30″-50″), as a substitute of radically completely different, making it a lot simpler to get a hipbelt that matches you no matter your torso measurement.

External Attachment Points and Compression System

The Osprey Exos Pro 55 has two compression straps on either side of the pack. The prime strap is anchored on on the prime nook of the entrance stretch pocket and runs to the body slightly below the entrance load lifter, whereas the underside strap is configured as a Z crisscrossing over the facet water bottle pocket earlier than attaching to the again of the hip belt pocket  I’m not an enormous fan of the Z-style threading sample as a result of I feel it makes it troublesome to strap cumbersome gear like snowshoes or a folding pad to the facet of a pack. I discover two horizontal-side compression straps to be optimum as a substitute.

But one factor that’s lacking from Exos Pro 55, however is supplied on the Exos 58, is a pair of sleeping bag straps for attaching a folding foam pad, like a NEMO Switchback or a Thermarest Zlite pad to the underside of the pack beneath the entrance stretch pocket. This could be very troublesome to do with the decrease Z-Style facet compression straps as a result of they’re not lengthy sufficient to simply match over considered one of these folding pads. You can do it, but it surely requires a number of effort and makes it very troublesome to place something into the entrance stretch pocket as a result of the pad is tightly compressed towards the pack. I’d advocate rigging up your individual elastic wire loops for attaching a pad to the gear loops working alongside the entrance stretch pocket as a substitute.

You can also’t thread the facet compression strap by means of the facet water bottle pocket on the Exos Pro 55 and it may solely run on the surface of the mesh pocket. This is as a result of the hipbelt pocket is the anchor for the underside facet compression strap…which is a screwy strategy to design it as a result of that compression strap will pull the hip belt off your hip if you should tighten it. These capabilities are finest decoupled.

But don’t let the Z-style straps (that are detachable by design) deter you from rigging up two horizontal compression straps as a substitute. One of the good issues concerning the Exos Pro 55 is the distribution of substances loops across the perimeter pockets, the pack bag seams, and even the highest lid, making it simple to rig up your individual customized compression system with an additional wire lock and a few guyline or a bit of webbing. If I used the Exos Pro 55 often, I’d most likely take away the facet compression straps off and exchange them with my very own wire and cordlocks.

• A light-weight perimeter body offers nice load switch and management

Dislikes

• Difficult to connect accent pockets to the shoulder straps or hipbelt pockets.

• No sleeping pad straps.

Comparable Ventilated (Suspended Mesh) Backpacks

There aren’t many light-weight (sub 3 pound) ventilated backpacks obtainable at this time, with or with out adjustable torso lengths.

Zpacks additionally has a number of fashions which are very aggressive with the Exos Pro 55 together with the Zpacks Blast 55 (See our Zpacks Blast 55 Review) and the Zpacks Arc Haul Ultra 60 (See our Zpacks Arc Haul Ultra 60 Review.) While each of those packs are a lot lighter than the Exos Pro 55, they’re additionally rather more costly. On the opposite hand, if you’d like a ventilated backpack with an adjustable torso size that’s arrange like an ultralight roll-top pack, they’re the one sport on the town.

Recommendation

The Osprey Packs Exos Pro 55 Backpack is a top-loading backpack with an adjustable torso size that’s simple to suit and configure for a lot of completely different sorts of mountain climbing and backpacking journeys. Weighing simply 2 kilos 1.2 ounces, it boasts a strengthened perimeter-style aluminum body and ventilated suspension that gives wonderful consolation and management for hundreds as much as 30 kilos. If you need a big however ultralight (55L) hydration-compatible backpack with an actual body and a prime lid, the Exos 55 Pro is a good selection that’s designed for multi-day backpacking, thru-hiking, and part mountain climbing.

The factor that I like much less about this pack is the best way it forces you to pack a sure manner on the subject of carrying water bottles, including accent pockets, or strapping gear to the surface of the backpack. I desire extra flexibility on this regard, however that’s my private desire. Despite that, I may see being completely completely satisfied utilizing an Exos Pro 55 for a long-distance or section-hiking backpacking journey, notably in scorching and humid climate the place a ventilated suspended mesh body is a big win.
