The CDT is our lightest, most basic backpack. With just over 50 liters of available space, the CDT is the largest of three frameless packs we make and is suitable for thru-hikes, day hikes, travel, and any distance back-country forays. The CDT pack continues the tradition of being a reliable, lightweight, and durable backcountry companion.

The maximum comfortable load in this pack is approximately 18 pounds or less. No matter what anyone claims, no frameless pack is comfortable over this load and the CDT is no exception. At these loads, the contoured shoulder straps and redesigned hip-belt result in a comfortable carry.

The CDT comes standard with a “Cinch Top” styled closure, though you can request a “Roll Top” closure if you feel that better suits your needs, the pack shown in the photo is a roll top. Stretch mesh front pocket, adjustable side pockets, and two hipbelt pockets help to keep you organized on the trail.

Original Green, Black, Red, Orange and Purple Blaze packs are sewn with our ULA 400 Robic Fabric, the toughest stuff ounce for ounce we’ve ever seen. The Multicam Camo pack is sewn with 500 Cordura Fabric. The Cordura is not quite as tear resistant and a little heavier than the Robic, adding an extra 2 OZ to the total pack weight. Either way, this is one tough pack that will give you years of hiking bliss, even if you are a bit tough on your gear.

NEW! Now you can customize the color of your ULA pack! Select “Custom” under the “Pack Color” dropdown, and add your pack to the cart. Then go to our CUSTOM page, select the level of customization you want and use our pack customizer to customize the look of your pack! NOTE: Custom charges are not refundable and returned custom packs will be assessed a $35 restocking fee.

Bottom Line? The CDT is a comfortable, durable, highly functional ‘ruck sack’ styled pack.

OPTIONAL FEATURES

TRAIL NAME EMBROIDERY (+ $15.00): Now you can have your trail name, or your real name, embroidered on your backpack! Not only is it a nice personal touch, but it’s a great way of identifying your pack no matter how or where you travel. Simply write your trail name, or your name, exactly as you want it to appear on your pack, in the text field above. Then, choose your thread color and font, and we’ll personalize your pack for you. Packs that have trail names embroidered on them are still returnable, minus a $35.00 fee. The cost of the trail name is not refundable.

If you look “mesh trucker hat” up in the dictionary, you’ll find a picture of this hat. In fact, this hat isn’t just the definition of trucker hat; it reigns supreme as trucker hat royalty. That’s why we’re adding it to the ULA line for 2019! Simply purchase a pack cover and/or rain kilt with your pack between now and December 26th, and you can get your hands on one before anyone else!

Made from cotton blend and mesh, this trucker has a mid-profile/ pro-model crown, adjustable snapback closure, curved visor, and a pro-stitched finish. It’s comfortable, breathable, and durable – kind of like our packs!

Available in One Size Fits Most, it should fit your head unless your brain is housed in an abnormally large cranium (in which case, “Congratulations!”)

Customize your hat to your pack (or clothes) by picking your hat color, as well as what color embroidery you’d like for the mountains in the ULA logo, and for the “ULA” text.

Black/White (Black Crown/Visor with White Mesh): Shown above with Fluorescent White mountains and Iron Grey text.

HIPBELT SIZING MADE SIMPLE

 
MEN & WOMEN

For the CDT, use your actual waist measurement to determine the hipbelt size you need.
 

MEASURING YOUR TORSO LENGTH

 
Torso measurement is the best guide we have for proper pack fit, but it isn’t foolproof. Generally we find that if you are between sizes on the torso it’s best to go with the smaller size, if you are between sizes on the hipbelt it’s best to go with the larger size.

To accurately measure your torso length for a correct pack fit, grab a buddy and follow the steps below…

  • Standing upright, tilt your chin to your chest.
  • Locate the largest lump on the back of your neck. It should be located close to the base of your neck.
  • From this large bone, measure (with the flexible tape) down the length and natural curvature of your spine to the top of your waist band, the top of which is resting on the top your hipbone. This measurement in inches is your torso length.
PACK SIZE TORSO LENGTH HIKER’S HEIGHT
SMALL 15″ – 18″ UNDER 5’6″
MEDIUM 18″ – 21″ 5’6″ TO 6’0″
LARGE 21″ – 24″ 5’10” TO 6’4″
X-LARGE 24″ + OVER 6’4″

CHOOSING A SHOULDER STRAP STYLE

 
J STRAPS
The J straps are the traditional straps, and work best on most men with average builds. If you are very large in the upper body you might need XL shoulder straps, give us a call for that. Many men with athletic builds, i.e. strong, square shoulders will find the S straps work better. Swimmers, climbers, weight lifters,surfers, triathletes, XC skiers, etc usually prefer the S straps.
 
S STRAPS
The S straps work best on almost all women and men with square shoulders and good posture. If you are a short torso, but with a larger upper body, give us a call, we may want to give you a slightly longer strap, there’s no charge for it, so don’t be shy, pick up the phone or send us an email.

Q: WHAT DOES RECOMMENDED BASE WEIGHT MEAN?

A: “Base weight” refers to the total weight of all gear carried — including the weight of your ULA backpack. This weight also includes things like water bottles and food stuff sacks, but not the weight of water and food as this will vary during each trip. Knowing your base weight will help you determine which suspension system will best handle your load on the trail.

Q: CAN A WATER BOTTLE FIT IN THE SIDE POCKETS? IF SO, CAN I REACH IT? HOW DO THEY CLOSE?

A: Each side pocket can accommodate two 1-Liter ‘Big Slam’ style bottles. A Nalgene-style bottle will also fit, but in your quest to lighten up, that should have been replaced a long time ago! In general, most people can reach back and retrieve a bottle, drink, and return the bottle to the pocket without removing the pack. The top of the side pockets are angled for easier access and adjust single-handedly with a cord lock and internal bungee to open and close.

Q: HOW DO I USE MY SLEEPING PAD IN CONJUNCTION WITH THE CDT? WHAT PADS WORK THE BEST?

A: Just about any lightweight pad (foam or inflatable) can be used for additional support and padding inside the Ohm 2.0. Three quarters and full length pads that can be folded (as opposed to rolled) work the best. If you are using an inflatable mattress, deflate, then fold it into 1/3’s or 1/5’s before inserting. We also supply a ¼ inch piece of open cell foam with the pack that works very well for those of you not carrying a sleeping pad.

    I own/have owned 3 different ULA backpacks: the Camino, the Circuit, and the CDT. I am 6′-6″ tall and these packs fit well in the L/XL sizing. I have used many packs since I started outdoor adventuring 43 years ago at the age of 10. With this said, the CDT is my all time favorite! I primarily use it for a ski touring day pack. It is light, strong and fits me well, so it is comfortable. I can carry everything in it in to survive in case I get stuck out overnight. It is a great weight saver to use a foldable z-lite sol as a frame sheet, for it gives the pack rigidity without a heavy, useless frame, and supplies an emergency sleep pad/frozen ground insulation. The specs are correct in that it is a comfortable pack, but don’t exceed 18 Lbs. I usually keep it around 14-16lbs. I can put the Z-lite, extra wool socks, fleece pants, a 800 fill down-tek 30 degree walking mummy bag, 800 down-tek vest, Esbit stove and 600 ml titanium pot, a titanium plate to use as a shovel and stove base, a SOL Escape Bivy, a space blanket and space blanket tube tent, hand warmers, flashlight, matches, Knife, Compass, fire starter, first aid, water bottles, balaclava, extra glasses, food( about 2,000 kcal), ski repair kit, kicker skins(when needed) and a few other emergency supplies–I think I conveyed how much this can carry, yet be lightweight, sturdy and comfortable. If one was to do research, they would find the design is an updated version of German and Swiss WWII era alpine rucks. I highly recommend this rucksack!

    I don’t have a ton of miles on my CDT,but the ones I did have were very comfy. This is my second pack from ULA, and it’s even better! A lot of thought went into the design and I have plenty of room for all my stuff. I am adding on some pockets (also great quality) only because I plan to also use this for local search and rescue. I prefer to travel lighter vs. punish my back (and discs). I know I am carrying the weight, but with this pack there were no hot spots or sore areas at all. LOVE it.

    I just complied a rigorous one day hike in the mountains of Utah with this pack. Before this trip I re-enforced the 1/4 inch foam pad by gluing a thin and light piece of card board material that was about 1/8 of an inch thick to the front side of the pad. This provided some great support and structure.. My hiking partner was really envious of this pack. He liked the fact that the pack is light before you put stuff into it. I told him if you start with a 3.5 to 4.5 pound pack you already have a heavy pack. That pound or two makes a pretty big difference in overall weight, especially for a 70 year old.. I had more that enough room for 120 ounces of water, two extra layers of clothes, and a lunch. I also had other supplies in the external stretch net pocket. This pack is ideal for one day excursions and could be used for a two hike trip by packing a tent, sleeping bag, and more food. This pack was so comfortable thatI forgot I was wearing it. This pack is well made and I feel it will last for many more trips. I highly recommend it.

    I am in love with this pack! I use a folding sleeping pad which works great as a back pad and stays neatly in place with the elastics included. With the sleeping pad in place, it transfers weight amazingly well and will stay upright if I take the shoulder straps off. For a frameless pack, that’s awesome. I’ve comfortably carried far more than the recommended weight this way, up to 26 pounds. I removed the included back-pad and water bottle holders to cut down on weight. The front stretch pouch works wonderfully as a pillow when stuffed with clothes. Love the roll top!

    I own the original version the conduit. It is the best pack I have ever owned. It held up through a 7 day through hike of the wind rivers. A solo trip from glacier park to Wyoming through Montana. A month long safari in Africa and this has held up. I have had 30lbs in this pack it is not at all I deal but with 260 miles between supply drops in northern Montana sometimes you do what you have too. My friend has the same pack his stretch mesh ripped ula repaired if for free. Awesome awesome.

    I got my CDT in the mail the other day. Right away I packed it and went for a hike. Wow! Best pack I have ever owned hands down. Super comfortable and excellent craftsmanship. Thank you so much! See you on the trail.

    I’ve had the pack for three years now and I love it. It is the most versatile pack I have. Right now I alternate between the CDT and a NF shadow 30+10. For the CDT I remove the back pad, the internal hydration sleeve, the inside pocket and the bottle cords. This gets the weight down to 20 oz. for the large torso model and I find those items unnecessary. If you pack correctly there’s no need for the back pad and the bottle holsters provide plenty of water storage. I’ve carried weights up to 25 lbs. without a problem. I find the pack to be very comfortable with S curve shoulder straps. I’m 185 lbs 6”2”. For those on the fence I’d say pull the trigger. It’s a great pack. It sometimes requires some creative packing, and you should be ultralight with your gear – 10-13 lbs before your water and food. I have the purple blaze and I think it looks great.

    I used this pack to hike from Geneva, Switzerland thru France and then thru the Camino De Santiago in Northern Spain (approximately 1200 miles). It proved to really be the perfect size and weight. I used stuff bags to pack the cdt which was perfect for this frameless pack. Even after 1200 miles this pack is still holding up fine. No rips or tears apart from the upper sowing on the shoulder straps where my shoulders sit wearing out a bit (not the part attached to back of the pack but just below). The only issue I have with my pack is that the shoulder straps are not sewn to the exact same spot on both sides. As I don’t know which side would be “right” I can’t say which side was wrong. They are just not on the same spot (about an inch off) so I had to compensate through adjusting the tightening straps differently on each side. All in all I still loved this pack and would definately buy it again or recommend it to others. I got the roll top cover and the camo color. Really love the look of the pack as well. People were giving me compliments.

    I seldom write reviews, but I have to say I’m so impressed with my CDT, I felt the need to share my opinion. I’ve traveled to Sri Lanka, Africa, and Patagonia using this as my carry on and day pack on shorter hikes. I’m kind of a back pack hoarder , and this by far is my favorite. Still looks new after several years of heavy use. Build quality is awesome.

    Another top notch piece of gear by ULA!

    This is my second ULA pack (Catalyst is other) and I just received it 2 days ago. I got the CDT to replace my old Lowe Alpine Contour 40, mainly for use as a larger, day backcountry ski pack with extra room for bivy stuff and/or Ham radio gear. Another great pack from ULA, I love it, it carried great with about 16lbs today on a short ski trip and feels like I could easily load it up more if need be. More than enough room. So far the back pad that comes with it works fine, just pack your stuff with care. Plenty of front and side pocket space. I had them add the roll top and a bungee. Thanks again ULA!

    Great Pack!

    Just received the pack in time for her maiden voyage in the woods of Michigan with my winter gear. Pack this thing right and it will wrap you in its loving embrace and float along the trail with you like it’s not even there. The craftsmanship on this beaut is top notch and seems amazingly durable for its weight. I swapped out the 1/4 inch back pad for a 1/2 inch piece of blue foam pad which gave it even more structure. Buy this glorious pack. Now.
