Backpack Group and Storage
The ULA CDT is an ultralight fashion backpack with a big primary compartment, a entrance stretch mesh pocket, roomy facet water bottle pockets, and zippered pockets on the hip belt. It has a roll-top closure that’s secured with facet webbing straps or could be buckled closed on prime. The roll prime itself doesn’t have a stiffener, snaps, or velcro to carry the edges closed when rolling it up however there’s a webbing strap that loops excessive to safe and compress the contents.
The CDT is hydration appropriate with facet hydration ports and two webbing loops inside the place you may cling a hydration pocket (offered individually). There aren’t hose keeper loops on the shoulder straps, nonetheless, so it may be a bit of awkward to handle a hose.
The pack’s facet water bottle pockets are strong cloth to guard them from abrasion and tearing. They’re massive sufficient to suit a 1 liter Nalgene or soda bottle with room to spare; it’s additionally straightforward to drag out a bottle whereas strolling and substitute it with out stopping to take off the pack. Each water bottle pockets have drains at their base and an elastic wire on prime that may be cinched closed and secured with a wire lock to maintain objects from shifting or dropping out. The elastic wire can also be helpful when storing longer objects which are additionally lashed to the edges of the pack with a compression strap, like a fishing rod or trekking umbrella.
The entrance of every facet pocket has a small gap you may stick your hand into though that’s not the intention; it’s a part of the shoulder strap suspension system which terminates on the base of every pocket. Whereas this attachment level helps pull the pack nearer to your again, small objects can fall out of the facet water bottle pockets and the facet pockets shouldn’t be used for that kind of storage.
Like many ultralight fashion packs, the CDT has a protracted entrance mesh pocket that’s splendid for storing moist gear or layers you need quick entry to throughout the day with out having to open up the pack’s primary compartment. I usually retailer snacks, my rain gear, a water filter, and an empty moist reservoir within the mesh pocket to maintain them away from my dry clothes inside the primary compartment. The stretch mesh has a really tight weave and wonderful sturdiness for on-trail use, however I wouldn’t advocate taking the CDT on rugged bushwhacking journeys if you wish to maintain the material intact.
Lastly, there are two zippered pockets on the outside of the hip belt, massive sufficient to retailer a smartphone, a point-and-shoot digicam, snacks, AquaMira bottles, bug dope, and such. The fronts of each pockets are hard-faced to stop tearing with heavy-duty zippers for sturdiness.
Backpack Body and Suspension
The CDT is a frameless backpack that takes a bit of apply to pack as a result of it has so little construction. There’s a foam pad held in place in the primary compartment by two elastic straps behind the shoulder straps. Whereas it protects your again from being poked by sharp objects, it’s very delicate and doesn’t present any construction or load switch to your hips. Many individuals take away and substitute it with a number of sections of a folding foam pad, like a Therm-a-Relaxation Zlite or a NEMO Switchback that’s thicker, stiffer, and makes the pack simpler to load. You don’t need to use the complete folding pad, as a result of it’ll eat up an excessive amount of area, simply 4 to six side-by-side sections.
The easiest way to pack the CDT after that’s to line the pack with a trash compactor bag and pack the remainder of your gear into it by stuffing it unfastened, with out utilizing numerous stuff sacks to arrange it. The rationale this takes some apply is that the CDT will barrel uncomfortably if you happen to stuff it too tightly, though you don’t need the contents to be too unfastened as a result of the pack carries extra comfortably when the gear fills out all of the empty areas within the pack bag. It’s virtually like your gear “turns into the body.”
Whereas it doesn’t have a direct connection to the hip belt, the downward power of the load is flush along with your again and does drive a few of the weight into the hip belt. Nearly all of the burden will nonetheless experience in your shoulders, which is why you need to maintain the entire weight of the contents under 25 lbs and ideally even much less.
In case you’re acquainted with the huge hip belt that ULA makes use of on their Catalyst, Circuit, and Ohm backpacks, the CDT hip belt is narrower and as befits a pack that carries lighter most hundreds. It’s additionally sewn on to the again of the backpack as an alternative of being replaceable so it’s nearer to your again and hips.
The CDT hipbelt has two tiers of webbing straps that join with a middle buckle, so it may possibly mildew across the angle of your hips to a sure diploma. I just like the pass-thru fashion hip belt on ULA’s bigger backpacks significantly better as a result of it’s wider and extra sturdy though that issues much less on the CDT as a result of it’s not supposed to hold heavy hundreds.
The CDT is accessible with J-shaped or female-friendly S-shaped shoulder straps which are higher for individuals with sloping shoulders and rounded chests. Males can use S-shaped straps too and I discover them to be much more snug alongside the edges of my torso. One factor value noting concerning the shoulder straps is that there aren’t any load lifters on them because you want actually need a body to anchor load lifters. They’re additionally much less essential on a pack designed for carrying lighter hundreds with a hip belt that’s set flush to your again.
Exterior Attachment and Compression System
The CDT solely has one tier of facet compression straps situated above the facet water bottle pockets. This makes it troublesome to connect cumbersome gear to the skin of the pack as a result of there’s just one strap to carry it on with. Yanking on that single compression strap additionally doesn’t compress the pack bag a lot as a result of the encircling cloth is just too delicate to transmit the power very far. I solely use these straps to safe lengthy skinny objects to the facet of the pack like a Tenkara fishing rod case.
The one different compression on the pack is supplied by the highest strap and the roll prime, from the highest down. There aren’t some other handy anchor factors or webbing loops alongside the pack seams to create your personal attachment factors utilizing wire and with some wire locks.
That stated, you may connect extra gear to the skin of the pack in a number of locations.
- There are pair of trekking pole straps and ice axe loops on the prime and backside of the entrance mesh pocket to safe poles or an axe.
- As well as, there are plastic rings, webbing, and daisy chain slots on the entrance of the shoulder straps to hold a satellite tv for pc messenger, accent pockets, or water bottle sleeves.
Pack Customizations
ULA affords an unprecedented variety of customization choices on the ULA CDT past the myriad coloration and cloth choices they provide. For instance, you may add a hoop body to the CDT with load lifters or a pass-thru hip belt, like those on ULA’s bigger packs. You may as well add backside straps to carry a sleeping pad or prime straps to hold massive objects on prime of the roll prime. These customizations add up fairly rapidly, however you may flip the CDT into extra of a “framed” backpack if you happen to like, though it might be cheaper simply to purchase a ULA Ohm which is the subsequent step up anyway.

Weighing 27.1 oz (768 g) it has a capability of 54 liters (36 liters of closed storage) making it splendid for backpacking journeys the place you’ve got very light-weight however “puffy” gear you could pack unfastened inside the primary compartment.
