Whether you’re chasing your PR or sweating it out at the gym, the Pinnacle Performance Short is as strong and sexy as you are. The soft-knit shell and bikini-brief liner keep you cool and feeling fresh. A contoured band hugs at the natural waist for a slim silhouette.
Why We Love It:
Tested, Tried & True: Independently lab-tested free from BPA and PFAS. Most brands won’t claim this — because they can’t.
Biodegradable Innovation: We use CiCLO®-enabled yarns—certified by ECO PASSPORT by OEKO-TEX®—that allow yarns like nylon and polyester to biodegrade like natural fibers. Instead of persisting for centuries, these yarns break down in a matter of years when exposed to landfill or ocean conditions.
Outer Shell: 92% CICLO Nylon, 8% Spandex
Liner: 88% CICLO Nylon, 5% Nylon, 7% Spandex

"Love these shorts, they are so lightweight and comfortable. The color is fun and bright. They run a little loose but that’s okay. They do not ride up at all. Pocket is a little tricky if you want to put your phone cause it’s a little too heavy and sags the shorts down. Overall great shorts just wish they weren’t so expensive I would buy more."
"I love these shorts! I have all three colors and wish there were even more because these are the ones I want to wear in every workout. The length is perfect and the liner is barely noticeable at all. I like the thick waistband- it gives a nice flattering shape and holds you in without cutting you off at the waist. I love that the material is stretchy but always maintains its shape. It is high quality, washes well, and holds up to intense workouts. I am 5'6" 150 lbs with an athletic shape and the medium fits me perfectly."
"Bought these in the citrine color and l love them! If my size in the other colors would have been in stock I would have bought one of every color. They are very comfortable! Will buy them in blue and black when they restock!"
"Nice fit and comfortable running short. I’ve switched to this for the clean fabric. Really happy with them"
"I love these shorts, they are so comfortable and do not ride up at all. Love that there is a brand that I can feel good about wearing and not worry about chemicals leaching into me. I wish they had more colors. They are very lightweight and soft material. Love them! If they weren’t so expensive I would replace all my shorts with these."
"I love the feel. These shorts are now my go to for running."
"TTS and super comfortable. Have gotten multiple compliments on the fun color!"
"I love these shorts, I just wish they were a little shorter. I love the material and how soft they feel!"
"In love with these shorts!! They are crazy comfortable, the high waistband is absolutely perfect, and they are so soft! I will be living in these this summer! You can tell the quality just to touch them."
"I have used these shorts for several months. They work well during running (interval and distance), CrossFit, strength session, sailing, and indoor rowing. These are very comfortable shorts and the color is vibrant. The wide waistband stays put. The material feels sturdy but cool and it moves well. My one issue is the liner fits a little more on the baggy side than I like."
