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.

S M L XL

The ULA Catalyst remains the tried and true workhorse of the ULA pack line. No matter where the adventure takes you, the Catalyst will be there - ready to carry loads of up to 18kg. If you are looking for a pack that will haul a bear canister, or carry your fishing, climbing or photo gear with ease, the Catalyst is an excellent choice. Not only will it carry a good sized load, but it can also be checked as baggage on a plane! The Catalyst has consistently been among the top 5 most popular packs on the Pacific Crest Trails and the Appalachian Trail.

Internal frame with a twin stay framesheet, comfy padded hipbelt, and contoured shoulder straps make for all day comfort even when you're loaded down. Front mesh pocket, dual hipbelt pockets, and Robic adjustable side pockets make it easy to stay organized whether you're on a thru, or just out for the weekend. Weighing only 50 oz – including all the extras! – this pack will lighten you up but still handle the toughest duties.

ULA has replaced the regular mesh front pocket with an UltraStretch™ mesh for added abrasion resistance and durability. Combination ice axe/trekking pole loops are now a standard feature; the weather is unpredictable, and we believe your pack should be able to adapt as fast as you can. We've also added low-profile loops to the top and bottom of these packs to accommodate removable top Y-strap and/or bottom straps.

Bottom Line? The Catalyst is a tough and light pack built for traditional backpackers.
