Whereas it carries hundreds as much as 30 lbs very effectively, the usage of thinner materials means it will likely be much less abrasion resistant than the Eja 58.

As an alternative of the rolltop closure widespread on most ultralight backpacks, it has a prime lid pocket (very helpful) and most of the exterior attachment options discovered on standard multi-day backpacks. There actually will not be many ultralight backpack choices with a girls’s-specific match, so if that’s what you’re searching for, this pack is price trying out.
Whilst you can swap to a extra minimalist roll-top backpack just like the ventilated Ladies’s Zpacks Arc Haul Extremely 60, doing so can require a fairly large change in the way you pack and work together together with your backpack through the day. Whichever method you select to go, Osprey and Zpacks are nonetheless the one pack producers to supply ultralight, ventilated, and adjustable torso-length backpacks designed for ladies. What’s up with that guys?
How is the Eja Professional 55 totally different than the Eja 58?
The Eja Professional 55 is a lighter-weight model of the unique Eja 58, and is totally different within the following methods.
- It’s 12 oz lighter weight than the Eja 58 (could range relying on sizing).
- Doesn’t have a second pocket beneath the highest lid.
- Doesn’t have separate sleeping pad straps on the entrance of the pack.
- The entrance stretch pocket has material loops alongside the edges that can be utilized to hold gear.
- The entrance stretch pocket has much less mesh and extra stable material for higher sturdiness.
- The left-hand hip belt pocket is open and never zippered.
- The adjustable torso size is secured utilizing small dowels as a substitute of bigger plastic discs.
- There’s a silicone print on the base of the suspended mesh to stop slippage.
- The sternum strap solely has three positions as a substitute of a sliding rail adjustment.
- The shoulder straps are much less padded.
- The shoulder straps have insufficient hydration hose keepers (see beneath).
- There’s no stow-on-the-go trekking pole holder.
- Makes use of thinner (200d) material in high-wear areas.
Backpack Storage and Group
The Osprey Eja Professional 55 could be very totally different from most ultralight backpacks as a result of it’s configured with a floating prime lid as a substitute of a dry-bag type roll prime. With a single giant prime zippered pocket (with key fob), the floating lid helps you to sandwich further gear between the lid and the highest of the pack’s essential compartment so you possibly can carry further tools like bear canisters, foam pads, or tent our bodies that received’t match inside your pack. The highest pocket additionally offers helpful entry to hats, gloves, snacks, and navigation gear and is indispensable for cold-weather use.
When you don’t want the highest lid on the Eja Professional 55, you possibly can take away it to avoid wasting gear weight. This reduces the burden of a small/medium Eja Professional 55 by 2.6 ounces bringing it right down to a decent 28.4 oz (1 lb 12.4 oz).
There’s a nylon flap beneath the highest lid that’s completely hooked up to the pack, what Osprey calls a FlapJacket, that covers the drawstring opening of the primary compartment. Whenever you take away the highest lid, the FlapJacket is used to guard the primary 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 way in which. When it’s not wanted you possibly can stuff it into the primary compartment or into the inner hydration pocket. Nevertheless, the FlapJacket shouldn’t be thought of a weather-tight cowl. Because the pack will not be marketed as waterproof, you’ll in all probability be utilizing a pack liner, so this won’t be a difficulty for you.
Whereas the Eja Professional 55 additionally has good open storage within the type of facet and entrance pockets, the primary compartment is the place the majority of this pack’s capability is. With over 3350 cubic inches of room, you possibly can put a ton of drugs and meals inside. Being a mainstream backpack producer, Osprey solely counts coated and zippered storage once they calculate backpack quantity. In case you are evaluating the amount of the Eja Professional 55 with a pack from a cottage backpack maker, bear in mind that they typically add in open and closed pocket volumes so the Eja Professional 55 will really feel fairly a bit bigger and maintain significantly extra gear.
Whereas the primary compartment curves inward to accommodate the form of the ventilated body close to its base, the primary compartment is so giant that the pack continues to be straightforward to pack. Nonetheless, as a result of it’s ventilated, you’ll need to place the heaviest gadgets as near your again and hips as potential. Apart from a hydration pocket, cling loop, and prime compression strap, there’s nothing contained in the Eja Professional 55 essential compartment like a sleeping bag compartment to interrupt up the seemingly cavernous area. Nonetheless, it’s straightforward to see inside the primary compartment as a result of frivolously coloured material panels assist channel gentle to the pack’s inside. I’d nonetheless advocate packing the Eja Professional 55 with a pack liner for moisture/rain safety (See 5 Ultralight Pack Liners In contrast.)
There’s a sleeve contained in the pack to carry a hydration bladder. Nevertheless, the mechanism to clip within the hydration bladder appears to be solely designed for Osprey hydration bladders and isn’t common for others. If it’s not suitable together with your reservoir, you possibly can let it fall to the underside of the sleeve or use a small carabiner to stick with it greater.
Osprey included hipbelt pockets on the Eja Professional 55 however they’re barely totally different than these on the present Eja 58. The left-hand pocket is now open on prime and doesn’t have a zipper. I assumed I’d hate that, however it’s truly fairly helpful for stuffing trash into. The appropriate-hand pocket continues to be zippered and enormous sufficient to suit an iPhone X into together with some snack bars.
However the pockets are sewn onto the hipbelt in such a method that the again of the pocket has to have the ability to curve when it wraps round your hips…which is an effective option to break a SmartPhone display screen. I’d advise towards placing something equally outsized and rigid into them.
The hip belt wings on the Eja Professional 52 are shorter than you would possibly discover on a comparable pack. Which means that the pockets are smaller and additional again than you would possibly count on. Regardless, the hip belt is simply as snug for me as different packs I’ve with longer belt wings.
Along with the primary compartment, the Eja Professional 55 has two stretch-side mesh pockets that can be utilized to retailer water bottles. Every pocket is bolstered with stable material on the underside for higher sturdiness and has a holster-style opening lower in entrance, which helps you to place bottles sideways so you possibly can pull them out and exchange them when on the transfer.
Although you possibly can put a 1 liter Nalgene within the pocket holster type when not sporting the pack, it’s powerful to do when the pack is full, and almost unimaginable whereas sporting the total pack. The pockets are fairly tall however when you put bottles in vertically, it’s not potential to get them into or out whereas sporting the pack. A smaller diameter 1-liter bottle will match within the holster opening however will stick out of the pocket far sufficient to be in the way in which of your arms. Nevertheless, a shorter, small-diameter bottle works high quality right here. I additionally discovered the holster opening helpful for my snack bottle and will simply get it into and out of the pocket whereas sporting the pack.
I initially thought the highest of the entrance stuff stretch pocket could be too free to be safe, however as soon as the pack is absolutely loaded, this doesn’t appear to be an issue. The material on the again of the stretch pocket is an enchancment over pockets with solely stretch mesh and makes the pocket extra sturdy.
Backpack Body and Suspension
The Osprey Eja Professional 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 might probably 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 Eja Professional 55 is what “makes” this pack. It’s tremendous light-weight and stiff, offering nice load switch to the hips, so you possibly can load up this pack and nonetheless get a really snug carry. The carry is definitely fairly superb, even with a full load.
This Eja Professional 55 additionally has an adjustable torso size with 4″ of adjustability that could be very light-weight and easy to make use of. It is a big profit for brand new backpackers who’ve much less expertise sizing and becoming a brand new backpack. You’ll be able to lengthen or shorten the torso size, the gap 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 mounted. That is finished utilizing a easy dowel and ladder system which slides up and down alongside the observe on the again of the backpack. I discovered the system straightforward to make use of, maybe much more so than a Velcro system (resembling these favored by Gregory).
Nevertheless, the padded portion of the shoulder straps is slightly too quick. When you want to put on a sleeveless higher physique garment, you could expertise some chafing from the shoulder strap buckle the place the webbing attaches to the padded strap. I discovered that by sporting quick sleeves I used to be capable of keep away from this drawback. Aside from this, I discover the shoulder straps to be snug.
The shoulder straps and hipbelt are each coated with a stretchy mesh material that’s comfortable and helps wick moisture to stop rubbing and chafing. The shoulder straps are frivolously padded and have one elastic hydration hose keeper strap on the entrance. Nevertheless, whereas the shoulder straps are snug, you’ll be considerably challenged to connect accent pockets to them, one thing that’s more and more in style with backpackers and day hikers alike. The identical could be stated for the frivolously padded hip belt.
Not like the Eja 58, the sternum strap on the Eja Professional 55 can solely be positioned in three areas. To regulate, you could push the plastic buckles via small twine loops which are barely sufficiently big. It takes a few minutes of fiddling to get these via, however thankfully, you solely must do to it as soon as.
For hydration reservoir customers, I like to make use of a hydration system and was disenchanted that the inventory technique for securing the hose to the shoulder straps is insufficient. There’s a very tight elastic on the prime of the shoulder strap that could be very arduous to get a hose via. It additionally holds the hose too excessive up on the strap which causes it to flop round whereas climbing. I put an elastic on the shoulder strap which is an appropriate resolution to this drawback. It will have been a easy matter for Osprey to connect a few elastic hose keepers additional down on the shoulder straps and the extra weight could be imperceptible. Or they might have used the magnetic system they use on a few of their different packs.
The Eja Professional 55 is available in two sizes (XS/S 13-17”), S/M (16-20”) when it comes to torso size The hip belt sizes are barely totally different, going a very good 5” bigger within the greater dimension (XS/S 26-45”, S/M 28-50”).
Exterior Attachment and Compression System
The Osprey Eja Professional 55 has two compression straps on both sides of the pack. The highest strap is anchored on on the prime nook of the entrance stretch pocket and runs to the body just under 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 tough 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.
However one factor that’s lacking from Eja Professional 55, however is offered on the Eja 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. That is very tough to do with the decrease Z-Type facet compression straps as a result of they’re not lengthy sufficient to simply match over considered one of these folding pads. You are able to do it, however it requires a number of elbow grease and makes it very tough 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 twine loops for attaching a pad to the gear loops working alongside the entrance stretch pocket as a substitute.
However 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 many nice issues concerning the Eja Professional 55 is the distribution of drugs loops across the perimeter pockets, the pack bag seams, and even the highest lid, making it straightforward to rig up your individual customized compression system with an additional twine lock and a few guyline or a bit of webbing. If I used the Eja Professional 55 usually, I’d in all probability take away the facet compression straps and exchange them with my very own twine and twine locks.

- No straightforward, present resolution for attaching a sleeping pad to the underside or again of the pack.

- Attainable chafing on arms from the shoulder strap buckles.
Comparable Ventilated (Suspended Mesh) Backpacks
There will not be a number of choices on the market for ventilated backpacks in girls’s sizing and match that weigh beneath 2 lbs. I’ve a Gregory Side 55 which might be one of many closest opponents at a few half pound extra. For me, the areas the place Eja Professional 55 shines are the burden and the adjustable torso size. The Side has greater hip belt pockets, an attachment for the hydration hose, and straps that work higher for exterior pad attachment. It comes right down to which options are most essential to you.
The Osprey Eja Professional 55 Backpack is a girls’s particular top-loading backpack with an adjustable size torso that makes it straightforward to dial within the match. Weighing slightly below 2 lbs, it has a bolstered perimeter-style aluminum body and ventilated suspension that carries hundreds as much as 30 lbs simply. It’s a nice alternative if you’re searching for a standard, but light-weight multiday backpack. I discover it handles hundreds with consolation, which is primarily what you need in a backpack. Coming in simply just below 2 lbs, the Eja 55 Professional is a stable alternative for anybody searching for a light-weight pack with a prime lid pocket.
My primary grievance with the Eja Professional 55 is the dearth of a very good resolution for holding a hydration hose beneath management. It will have been straightforward for Osprey to include a greater technique as they’ve finished on different packs. I additionally I dislike utilizing the Z-style compression straps for a pad or different cumbersome merchandise. You may make it work, however then the straps could also be very tight over the facet pocket, making it tougher to make use of. Nevertheless, I’ve but to search out the right pack that does every thing I would like simply the way in which I prefer it, you could count on to make some compromises. It was not arduous to regulate the Eja Professional 55 to my liking or change my strategies to work with the pack. The consolation and weight financial savings are price slightly fiddling.
