Whereas it’s priced at a premium, the NorthRim is unquestionably value upgrading to over Hyperlite’s different backpacks should you spend the vast majority of your time climbing off-trail, you’re very onerous on backpacks, or simply need one that can final for quite a lot of years.

The Worth of Woven Dyneema
The Hyperlite Mountain Gear NorthRim 55 is almost equivalent to each different 55 liter backpack the Hyperlite makes apart from the truth that the underside of the pack and the outside pockets are made with Woven Dyneema. Woven Dyneema is an order of magnitude extra sturdy than the Dyneema/Polyester laminate that Hyperlite makes use of on their cheaper backpacks and is value paying a premium for if you’d like a pack that can survive heavy use in extremely abrasive terrain. (Notice: We evaluate Woven Dyneema and Extremely 400, a more recent sturdy woven cloth beneath.)
Abrasion happens everytime you set your pack down on sandy floor or gravel; when your pack brushes in opposition to canyon partitions and rock faces; otherwise you bushwhack off-trail the place the vegetation whacks again. Do it sufficient and the backpack cloth will get thinner and thinner till holes type and it turns into unsalvageable, irrespective of how a lot duct tape, Tyvek tape, and Shoe Goo you utilize to patch it up. I’ve worn irreparable holes within the bottoms of the Hyperlite Mountain Gear Southwest 40 and SouthWest 55 backpacks from abrasion, so I’ve first-hand expertise on this division.
However the Woven Dyneema on the outside of the Hyperlite North Rim 55 is far more abrasion resistant than the Dyneema/Polyester laminate utilized in Hyperlite’s different backpacks as a result of it’s made by weaving collectively Dyneema fibers, that are stronger than metal, into material, quite than gluing a small proportion of Dyneema Fibers to 50D or 150D Polyester, which is the fabric that Hyperlite makes use of of their different backpacks.
Hyperlite’s NorthRim backpack is notable as a result of it’s arguably the primary off-the-shelf backpack that comes with Woven Dyneema as a cloth. Whereas Cilogear and Alpine Luddites supply Woven Dyneema as a cloth possibility on their packs, they primarily promote dearer, custom-made packs for climbers the place abrasion can also be a priority.
Backpack Storage and Group
The Hyperlite Mountain Gear NorthRim 55 Backpack is specified by a conventional ultralight type with a big foremost compartment, facet water bottle pockets, and a big rear pocket. The primary compartment has a dry-bag type closure system which offers glorious high compression for stabilizing your load. The ends of the dry bag closure may be clipped collectively on high of the pack or secured to straps alongside the perimeters. When doing so, the free straps may be clipped collectively on the entrance facet of the pack, offering a pleasant attachment level for cumbersome gear.
The highest of the roll high has a velcro stiffener to facilitate rolling and maintain the 2 sides collectively. Some folks discover the velcro stiffener to be a nuisance as a result of it catches on clothes. Over time and repeated rollings, the stitching, and materials holding the velcro degrades and throws off threads, although the whole failure of the roll high is unlikely.
There are 5 exterior pockets on the NorthRim 55 backpack, two facet water bottle pockets, a bigger entrance stretch pocket, and two hip belt pockets. All the pockets are made with Woven Dyneema. There’s no exterior mesh to dry damp gear. The massive entrance stretch pocket has a drain gap within the backside, however the facet pockets don’t. Water bottles saved within the facet pockets are additionally reachable and replaceable whereas carrying the pack, vital, however they generally tend to come out when bushwhacking or scrambling. The hip belt pockets, which have been enlarged by Hyperlite lately to make them helpful, have waterproof zippers and zipper pulls, a usability element left off of many ultralight backpacks.
Whereas the exterior pockets and the bottom of the pack are lined in Woven Dyneema, the inside pack bag is made with the 150D Dyneema/Polyester laminate that Hyperlite makes use of on their different backpacks. That’s effective as a result of the entire excessive abrasion factors are lined with extra sturdy Woven Dyneema. The inside pack bag is seam-taped and it’s NOT hydration appropriate: there are not any hose ports and there’s no hydration sleeve, though there may be an inner webbing loop the place you would cling an adjunct pocket or bladder from. This pack is beneficial for packrafting and having hose ports could be a non-starter when it comes to protecting the inside dry.
Once I pack the NorthRim, I put my sleeping bag stuffed in a dry sack on the backside of the pack after which stack my meals bag on high of it, stacking my tent or hammock and different heavy objects up the again panel as I am going. I stuff lighter-weight insulating layers and clothes behind the heavier objects to carry them in place after which put my lightest objects within the extension collar (primarily clothes and private results). I then use the pack’s roll-top to compress the objects within the extension collar and shrink the amount they require. This weight and quantity distribution offers the very best load management since heavy objects are positioned close to my hips and there’s a direct switch of kinetic power from my core to objects positioned simply above the small of my again.
Backpack Body and Suspension
Hyperlite makes use of a quite simple however efficient body system in all of its multi-day backpacks. The packs use body stays that are pre-bent aluminum rods housed in keep pockets contained in the pack behind the shoulder straps. They are often eliminated and bent to customise the pack on your dimensions, however they need to work for most individuals out of the field. The shoulder straps are sewn on to the inside pack bag simply above the body strays, which terminate behind the hip belt. The hip belt is sewn onto the backpack and never detachable, which is sort of efficient in bringing the pack near your hips for load switch.
Load lifters are notably absent on Hyperlite’s backpacks (See #13 on this interview with founder Mike St Pierre) as a result of correct again panel sizing obviates their necessity, in keeping with Hyperlite. I’ve used 4 Hyperlite backpacks and by no means missed load lifters as a result of the pack sits very near my again, stopping it from canting backways.
I attribute this to 3 elements: torso size match, the attachment level of the shoulder straps, and the sewn-on hipbelt. Maybe it’s luck, however a measurement giant Hyperlite pack suits my torso completely, whereas the shoulder straps and hip belt place the pack very near my torso so the pack appears like an extension of my physique quite than a hitchhiker. It’s not so good in sizzling and humid climate as a result of there’s no again air flow, however the match is out of this world.
The hip belt of the NorthRim is evenly padded with a stretch mesh which is what I desire for a great hip wrap, with a beefy entrance buckle for sturdiness. You don’t want an enormous hip belt for lighter-weight masses. An enormous buckle can also be vital for winter backpacking since small hip belt buckles fill with snow and develop into unimaginable to shut. (It’s one of many explanation why UL backpacks make sucky winter packs.)
The shoulder straps even have mild padding, with sewn-on daisy chains that make it straightforward so as to add accent pockets, like the enduring Hyperlite Mountain Gear Waterproof Shoulder Strap Pocket, water bottle sleeves, or a satellite tv for pc messenger to the straps. The sternum strap slides up and down the daisy chain webbing and is straightforward to reposition. However the shoulder straps are solely accessible in a typical J-shape, so that they’re much less fascinating for folks with breasts or sloping shoulders. The hip belt is equally “unisex” with out provision for feminine backpackers.
Backpack Compression and Attachment Factors
The NorthRim 55 has two tiers of facet compression straps that can be utilized to connect gear to the skin of the pack. A backside compression strap runs horizontally outdoors every water bottle pocket, whereas the higher strap is oriented at a diagonal to convey the load nearer to the wearer’s again for higher load-to-hip switch.
In use, I decouple the underside compression strap over the water bottle pocket as a result of I discover it interferes with getting water bottles into the facet pockets once I’m carrying the pack. As an alternative, I route the webbing out of the way in which via extra buckles on the again of the pack which can be utilized to connect extra gear, like snowshoes. HMG sells further webbing straps for this objective as an add-on though there’s nothing stopping you from rigging up some wire and rope locks as an alternative.
Along with the roll high, which offers glorious high compression, there’s a Y strap that runs from the entrance of the pack (between the shoulders), over the roll high and attaches to the again of the pack. This strap is nice for securing cumbersome objects like a foam pad, rope, or tent physique to the highest of the pack. Nonetheless, when bushwhacking, I like to recommend protecting this stuff contained in the pack as an alternative of on the outside lest they get caught on vegetation or shredded.
Different Extremely Sturdy Backpacks
Advice
The Hyperlite Mountain Gear NorthRim 55 Backpack is a extremely sturdy pack designed for off-trail, cross-country adventures that can rip most ultralight-style backpacks to shreds. In the event you’re tough on backpacks however nonetheless need one that’s light-weight and extremely waterproof, the NorthRim 55 is a good possibility.
Equally, at house on the path in addition to off, the NorthRim 55 Backpack has the additional quantity required for longer or extra technical journeys when you must carry further gear or clothes. I primarily use mine for bushwhacking and climbing up wilderness rivers on multi-day Tenkara fly fishing journeys, that are moist scrambles alongside boulder-strewn river banks seeking wild brook trout. I discover the abrasion and water resistance of the NorthRim to be an actual plus on these journeys as a result of I can drop my pack with out worrying about ripping it up or soaking the contents.
Woven Dyneema vs Extremely 400
In the event you’re looking for a sturdy ultralight backpack, you’ve most likely come throughout a brand new backpack cloth known as Extremely, which most of the cottage backpack producers have began making backpacks with. Extremely 400 (denier) is a water-resistant materials equal to Woven Dyneema when it comes to abrasion resistance that may also be seam taped to make backpacks extremely water-proof. Packs made with it are additionally barely cheaper than the Hyperlite North Rim.
Within the mid to long run, Extremely is anticipated to displace Woven Dyneema as the popular cloth for making extremely sturdy ultralight backpacks. On account of upstream acquisition exercise, the availability of Woven Dyneema is anticipated to dry up and I’ve heard rumblings from inside Hyperlite that they could ultimately substitute their use of Woven Dyneema with Extremely. Whether or not they undertake the usage of Extremely materials throughout all of their backpacks stays to be seen. They could don’t have any different. Be suggested, that the present formulation of Extremely offered as we speak isn’t a slam dunk, both. I hear a brand new formulation is within the works to handle shortcomings within the waterproof membrane in use as we speak.
In any occasion, I nonetheless anticipate Woven Dyneema to vanish. Within the meantime, many different ultralight backpack makers supply new packs made with the Extremely 400 cloth, together with Zpacks, ULA, LiteAF, Search Exterior, Superior Wilderness Designs, and Mountain Laurel Designs.
