Our backpacks no longer include hydration sleeve, internal stash pocket, hand loops or water bungie bottle holders. They are available as add-on items going forward, and can easily be added from the cart, or from the Accessories.

The Photon is the little brother of the CDT, our most basic backpack. With nearly 35 liters of available space, it's suitable for dayhikes and any distance backcountry forays. This is the medium size of our three frameless packs. It is ideal for travel or lightweight hiking.

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 Photon is no exception. At these loads, the contoured shoulder straps and hip-belt result in a comfortable carry.

The Photon 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. Roll tops will add about 4 oz to the pack weight. Stretch mesh front and side pockets, along with two hipbelt pockets help to keep you organized on the trail.

Now Available in Xpac! Read the "Customization" section below to learn more.

Bottom Line? The Photon is a comfortable, durable, highly functional ruck.

PACK WEIGHT

Listed weight is for a size medium torso with size medium hip belt. Our weights are as shipped including all the removable items. Packs with roll tops will be about 4 oz heavier.

CAPACITY

REC’D MAX LOAD: 18 LBS OR LESS
REC’D BASE WEIGHT: 12 LBS OR LESS
 
“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.

HIPBELT SIZING MADE SIMPLE

 
MEN & WOMEN

For the Photon, use your actual waist measurement to determine the hipbelt size you need. If your measurement falls between our size ranges, go up a size.
 

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″

Have any questions or don’t quite fall in the normal range? Give us a call or send us an email!

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 a 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.

Q: HOW DO I USE MY SLEEPING PAD IN CONJUNCTION WITH THE PHOTON? 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 ordered it without a hip belt for a daypack and it is so comfy loaded up that I am going to take it for some overnighters (or more) this summer. I love it. It’s incredibly well made, as is everything by ULA.

  2. Rog Wilmers (verified owner)

    Just received my custom Photon. CDT pockets and a one inch webbing belt make this the perfect small pack. I like it so much I see a CDT with the simple belt and roll-top closure in my near future. Thanks Chris for taking custom orders. I couldn’t be happier!

  3. Julia Young (verified owner)

    I ordered a pack on March 13, 2019 and express that I needed the package by Friday I was amazed that when I went to check the mail this morning, the package was there. top-notch customer service top-notch quality packs

  4. S Hill (verified owner)

    Walked the Camino de Santiago for 500 miles. Great everyday pack for everything I needed and was still able to take as a “carry on bag” on airplane. Would definitely recommend.

  5. K Bizzle (verified owner)

    This pack replaced an Osprey hydration pack that was beyond uncomfortable. This pack is my Jam. I take it on day hikes. I have been using it for over a year and it is still going strong. Holds everything I need it to for a family of five and still has plenty of space for more. Would definitely recommend.
