All the Support you Need

Training hard looks different for everyone. For some, it means setting an easy pace that allows you to go farther than you could have thought possible, while for others, it’s putting in shorter intervals while your heart hammers in your chest. As our perspective may differ from one runner to the next, our gear must adapt, support, and empower us to train with every ounce of effort. The Allston Adjustable Bra features a convertible design, adjustable straps, and our most supportive fabric yet so that as you push yourself, you’re thinking about the sweat you’re putting in, not your bodywear giving out.

Up to You

The straps can easily convert from over the shoulder to a racerback fit using the ergonomically placed clip at the back. Without being clipped, the bra allows for a relaxed lift, but when clasped, it touts the additional support needed for harder efforts.

Adjust and Adapt

The bottom band is finished with hooks that allow for further adjustability throughout the circumference of your body, and the straps are also modifiable, with the ability to lengthen or shorten depending on the size of your bust and your preference of support.

Stability and Support

As the most supportive bra in the Tracksmith wardrobe, the straps utilize a layer of internal stabilization so as to not stretch out over time. In addition, the silhouette is lined with a power mesh to maximize the fit and support from all directions so that you feel secured and not just compressed.

Change is Good

The bra was designed with the goal to embrace our bodies’ differences. The convertible straps allow for either a relaxed fit or a comfortable lift made possible with a clip at the back. Other than modifying the silhouette from a classic style to a racerback, the straps also adjust in length to hone in on the customization needed to support and stabilize each and every runner. Finally, the band accommodates the chest with three sets of hooks to maximize comfort.

A Harder Effort

There’s an uncelebrated triumph that comes with the sweat burning in your eyes, the uncomfortable tension in your muscles, and the aches and pains that build after you put in your hardest effort. When you’re too exhausted to celebrate your ability to conquer a workout that’s set your body on fire, you may not be jumping for joy as you stop your watch, but internally, you are resplendent with accomplishment. You hold your head high, in awe of your body’s ability to support the movement that just unfolded, equipped in the Allston Adjustable Bra to hold you up time and time again. And with that, you look forward to the next time you get to feel that spark of achievement.
