Built with the same top of the line materials as our award winning Helix wetsuit the core short is designed to simulate the lift of a wetsuit resulting in a seamless adjustment to swimming on race day. It will improve your distance per stroke, speed and boyd position all without the bulk and drag of a pull buoy. No longer are you limited in the strokes you can do. It provides improved swimming in all four strokes while allowing natural kick, hip rotation and turning. The core short is positioned to become a staple training tool for swimmers and triathletes of all abilities. 


Super buoyant Aerodome rubber in front, premium Yamamoto neoprene in the back and thinner side panels to promote rotation.


Bright orange graphics on the hips provide immediate feedback to the swimmer and coach on the pool deck of proper hip rotation.


High quality jersey liner including our signature orange jersey makes taking the core short on and off a breeze.


SCS coating makes the core short durable and hydrophobic

    Updated review: Works well if...

    Posted by John on 14th Apr 2015 are comfortable with the low riding fit. I wrote the "Short Waisted fit" review below. I've stopped fighting the fit (2 swims), let the shorts ride low where they want to be, then cinch the waist tie down. Before, I was hitching them up, then tightening the waist cord, so when they slid down, they were too loose and ballooned open during push-offs. Now the fit is much more secure feeling and there is only a small amount of water flowing into the shorts along the small of my back during turns. The buoyance is great, and they allow me to work my kick, unlike a pull buoy. Also, overall my body position in the water feels much more like I'm wearing a wetsuit, than it does when I use the pull buoy. So, go with the fit and enjoy.

    Short waisted fit

    Posted by John on 13th Apr 2015

    I'm training for 70.3s and wanted an alternative to a pull buoy that would help me work on my kick. These float my hips well (about the same as a pull buoy), and free my legs up, so work pretty well in that department. But, the fit is dicey. I have a 34" waist, and based on reviews elsewhere, bought he XL. They are still very tight, and despite sizing up, ride extremely low - I can't pull them up anywhere near as high as my jammers. In addition, the waist is rolled over neoprene, so is fairly thick and slick, making it hard to cinch the waist down tight enough to keep them from gapping in my lower back during push-off and scooping in water while simultaneously sliding down my waist. These things need a wider, thinner waist band and silicone or similar gripper to keep them in place. Great idea, but mediocre execution.
