The Mobius Tri Short is compressive without excess tightness. We have taken the pattern of the Forza Trishort with 4 pockets, put in a fleece (minimalist) pad, then replaced the Forza Fabric with Mobius™ Comfort Compression fabric. The result is a high performance compression tri short that is comfortable, not tight.

Great shorts but the drawstring-waist cord length is so unnecessary

Excellent size guide on the website. I went with a Medium and it fit perfect. However the drawstring waist cord is so long. Even when tied there’s over a foot of extra length. It would be a bad idea to cut it off because the plastic trim pieces would make the laces fal inside the short... thus you wouldn’t be able to thread it back through the waist band

Hi Christian, Thanks for the feedback. Glad to hear our sizing guide worked and you love the shorts. Please feel free to remove the draw cord. If you need it again we have a helpful video on how to put it back. You can find it here ~

loooooooooooove the mobius

the mobius material is the perfect thickness and stretchness. it is a little longer than i like but the cuffs are easy to flip up. and I looooove the low-cut waist

As a longtime and loyal DeSoto customer, I can vouch that these shorts have gotten even better with the latest version. The material is excellent. The pockets are perfect. The quality is top-notch. I use them for all my workouts: running, cycling and yoga.

Mobius Tri Short 4-Pocket: Simply the best.

Excellent. Great shorts. Most Tri shorts have too much excess padding for me and I get chaffed. I'm 5'10" 150 lbs. I bought the medium and they are the perfect size. The DeSoto shorts have the fleece (minimalist) pad Very comfortable. Just enough padding to be useful and no chaffing at all. The shorts fit firmly on my legs. I've used these for my long rides (100+ miles). Running is great with them too. Equivalent to a track short. I'm looking forward to the races to start back up so that I can use them in Ironman races.

Great shorts for riding and running

I love my deSoto shorts. I often have to have my phone or keys on me for my rides and runs. The pockets are great for this and the shorts are very comfortable.

The size chart above should serve as a general guide. If you would like assistance in determining the proper size, please send the following information to

WEIGHT - Accuracy helps us provide a more accurate size for you.
CHEST - Fullest part of breast, measured as the largest part of circumference right over the pectoral muscle.
WAIST -  Circumference measured at the belly-button line - this is NOT the same as your pants waist size.
HIPS - Circumference measured at the widest point, NOT at your hips where your belt may go. Typically this will measure just a few inches below your hip bones and around the largest part of the glutes.

If you do not have a tape measure and you need something to measure with, use a belt, or smart phone power cord, and a ruler.
