ULA Equipment ULTRA Ohm 63L Backpack
S Straps vs J Straps? Torso size? Follow this helpful guide to get the best fit.
1. TORSO FIT
- Standing upright, tilt your chin to your chest.
- Locate your C7 Vertebra - the large lump at the base of your neck.
- With flexible tape, measure down the length and natural curvature of your spine to your iliac crest/the top of your hipbone.
- This measurement in inches is your torso length.
TIP: If you're between 2 sizes, order the smaller size.
2. TORSO CHART
| Pack Size | Torso Size | Hiker's Height |
|---|---|---|
| Small | 15-18in | Under 5'6" |
| Medium | 18-21in | 5'6"-6'0" |
| Large | 21-24in | 5'10"-6'4" |
| X-Large | +24in | Over 6'4" |
| Kid's | 12-18in | Kid [Under 5'4"] |
We've found most people in these height ranges fall into these torso/pack sizes. That being said, it is always best to measure your torso using the guide above.
3. HIPBELT FIT
Use the following method to determine your hipbelt inches, then head to Step 4 to see the hipbelt size you need.
MEN
Pant Waist Size + 2".
WOMEN
CURVY HIPS: Smallest part of your waist + 5".
STRAIGHT HIPS: Smallest part of your waist + 3".
KIDS
Smallest Part of waist + 2".
4. HIPBELT SIZE CHART
| Hipbelt Size | Measurements |
|---|---|
| XX-Small | 18-26in |
| X-Small | 26-30in |
| Small | 30-34in |
| Medium | 34-38in |
| Large | 38-42in |
| X-Large | 42-47in |
| XX-Large | +47in |
Find the hipbelt measurement you calculated in Step 3 on the chart. That will be your hipbelt size.
TIP: If you are on the outer edge of a size, order the larger size. [ Ex: If you are 38", you will notice 38" is the last number of the Medium Hipbelt and the first number of the Large Hipbelt. You would want to order a Large.]
5. SHOULDER STRAPS
The downward slope of your shoulder profile usually determines strap preference. You can assess your shoulder slope profile by looking in a mirror or having a friend look at the angle of your shoulder from the base of your neck to your shoulder point.
If there is relatively little or no downward slope, you have what is referred to as flat or squared shoulders.
If there is a noticeable downward slope, you have what is referred to as standard or sloping shoulders.
J STRAPS
J-straps are the traditional straight straps. They are best suited for people with flat or square shoulders, as their flat shape provides better surface contact and less rub.
S STRAPS
S-straps contour body curves. They are best suited for people with standard or sloping shoulders, as their contoured shape better hugs your shoulder slope.
TIP: If you have a short torso but a larger upper body, you may need a slightly longer strap. If you are very large in the upper body, you might need XL shoulder straps. Contact us, and we would be happy to make these customisations so your pack is comfortable and fits well.
The ULA Equipment ULTRA Ohm 63L is the same Ohm you know and love, only stronger and lighter than ever. Purposefully constructed of Ultra 400X in high abrasion areas and Ultra 200X in low abrasion areas, ULA have selected a fabric matrix that maximizes durability while keeping the pack ultralight at just 887g.
In their commitment to making quality, durable backpacks that last a lifetime, they've been hesitant to build packs out of many popular ultralight fabrics. Why Ultra? 15x stronger than steel by weight, twice as abrasion resistant as standard 420D nylon, and waterproof to 200 psi, they've finally found an ultralight fabric that matches ULA's high standards. Front pocket is ULTRA StretchMesh for added abrasion resistance. Note that to maximize water resistance of the ULTRA Ohm, these packs do not have bladder hose ports.
The Ultra Ohm was built for the fast hikers who travel light but still take a prudent amount of gear to be safe and comfortable. Combining a 1.2 oz Carbon Fiber/Delrin active suspension hoop and near full-body compression, the Ohm maximizes load control, weight transfer, compression, and overall pack rigidity in an ultralight package. This pack uses the same belt and shoulder strap system as our larger packs, so comfort and weight transfer are optimal. Like their larger packs, the hipbelt can move up or down in its sleeve, allowing you to fine-tune the torso length. This pack comes standard with a roll-top closure.
The Ultra Ohm is a full-featured, active full-suspension, ultralight pack that offers exceptional load control, on-trail functionality, and full-body compression.
